    • Test: Samsung 250GB SSD 840 EVO

      Tags: Dell Latitude E6220, E6320 Battery , Latitude E6420 


      The efforts to make Samsung SSDs in more frequentable TLC are not in vain . These SSD 840 EVO show that with a little common sense , you can design good products with this type of chips. What tickle the top names on the Dell Studio 1558 market, and the best perf / price ratio?

      Our first test of an SSD based on memory chips TLC ( Samsung 840 ) was not conclusive. Indeed , the performance was not at the top, the life of cells inevitably called into question, and in return, the selling price at launch was not as interesting as that. Our verdict was then logic at this price, you turn in a heartbeat to the models using MLC memory chips . A few weeks ago , Samsung launched an evolution of its SSD 840 with the 840 EVO . The Dell Inspiron 1545 program always TLC memory, but many optimizations firmware and some advanced mechanisms for circumventing these defects memory chips that store three bits per cell , and are therefore slower and less enduring .

      Art around the limitations of TLC ( and small counterparts ... )

      In 2.5 '' 7 mm thick, the Samsung SSD 840 EVO is available in capacities of 120 , 250, 500 , 750 and 1000 GB , while the classic 840 is happy with the first three sizes. On their PCB , the Dell E4300 Battery controller used is changing. Instead of MDX which couples three ARM Cortex -R4 @ 300 MHz, the MEX used on EVO sees its operating frequency increase to 400 MHz. Also , TLC used is denser , and passes an engraving 21 nm to 19 nm. And since these chips have their doubled ( from 64 to 128 Gbps ) capacity , it says that Samsung can now climb in total storage capacity . Nothing to spoil the 3 year warranty is confirmed, and the claimed performance of the sheets have been revised up from 840. In short, you 'll understand that Samsung has put the dishes in the main to try to impose the SSD based on TLC with the 840 EVO .

      If we passed the  XPS M1330test bench models 250 and 500 GB, and the performance of the latter also have their place in our ongoing comparison , we chose to focus our analysis on the 250 GB ( even if it is worse . .. ), for the simple reason that the vast majority of SSD we tested so far are of equivalent capacity. Exactly, that give the results of these tests, do you ask ? And just imagine , although they are not bad , although a relative softness in writing under the Crystal Disk Mark is a little dip in the main ranking. It is clear that the optimization of the firmware, the boost given to the controller and the XPS 1340 batteries mechanisms by Samsung are compelling, but the negative effect is felt in some tests, such as Crystal Disk Mark Specifically , we are working on blocks with 4 GB Explanations .

      The brand chose to use some memory chips of 840 EVO as the SLC , and therefore are storing one bit per cell in a memory "buffer" . The amount of cells and TLC NAND flash used varies depending on the storage capacity of the 840 EVO model , and our model of 250 GB, for example, are 9GB TLC chips that are used as 3 GB of SLC chips (18 GB TLC used on the 500GB model , the 27 GB and 36 GB 750 GB 1 TB). This has the advantage of faster data writing , which first passed the SLC before then to be duplicated to the TLC . A system already seen on the SanDisk Ultra Plus as the nCache ( but MLC chips ) , which here takes the nickname TurboWrite . The results obtained by caching data on this pseudo SLC memory are obviously very good and can circumvent the shortcomings of the Dell E4310 Battery performance side TLC .

      However, be aware that if - our SSD - we had to write a file larger than 3GB (which of course we tried to do ), the first 3GB of TurboWrite have well and it jumps to about 490 MB / s sequential write , then once past this stage, the write speed falls at around 250 MB / s. 's why scores reassembled in Crystal Disk Mark writing are bad enough , while on blocks of smaller size, the results are much better. At this level , our protocol clearly hampers the 840 EVO 250 GB, which does not feel the 500GB model , and for good reason , it has 6 GB TurboWrite ... Result , it appears much higher in our charts , and our protocol proves to be a much better option. Still, the 3 GB files and are rare in the daily use of a computer, so it is fashionable to take advantage of increased  HP G32 Battery performance under this limit . It's pretty weird to write, but this point of view , it would almost succeed to ignore write performance of 840 EVO 250GB under our protocol , which eventually distort things a bit . But hey, we would not repeat our protocol so as to put forward specific product from Samsung ...

      Samsung plays the magicians

      The other big flaw chips TLC NAND flash is of course their life . We will not repeat here you hit the lecture , but rather direct you to our review of the Samsung 840 to understand why and to what extent the TLC cells wear out faster . In this context, and as is the case on many SSD , Samsung has introduced its 840 EVO what is called the Over Provisioning . That is an area of ​​memory kept virgin, so that these cells may be sought in time to replace any dead cells , extend the  HP G4 Battery life of the SSD and keep the storage capacity initially proposed . A quick tour of the excellent management software (SSD Samsung Magician ) shows that the user retains control over this data . Base , the amount of memory reserved for the Over Provisioning is 10% , while most hard opt for 7%. But what is interesting is to choose how much memory you want to allocate for this function. Those who want to get some useful GB on their SSD can lower this value, on the contrary, those who do not want to take any chances , and do not fulfill their record, can increase the amount of Over Provisioning (which justifies all the more on an SSD -based TLC) .

      Since we are in the app Samsung Magician ( version 4.2) , note that this is a small software that very well done many SSD manufacturers should follow . Very clearly, it allows a few clicks to optimize its operating system for using an SSD to check whether an update of the CD is available online to perform a secure erase its data and even start a small built-in benchmark ( which of course we prefer our usual third-party solutions ) . In addition, we note the presence of a RAPID mode function compatible with Pro 840 for example, but functional with EVO . Strange, the G6 Battery active recovery on some tests , and we realize that we have improved in performance ( even more so with the built- in benchmark Magician ) . But then , how does something akin to a " potato" mode?

      After information, it appears that Samsung has developed the RAPID mode based on the available memory on the user's system . If all do not benefit to the same extent (since better to have his elbow a PC powerful enough to maximize its effects) , the RAPID mode enhances the perception of SSD performance , which will be doubled up . This mode uses 25% of available RAM and up to 1GB of RAM. Too bad, this parameter is impossible to manually edit , and holders of 16 or 32 GB of DDR3 might have liked to allocate more resources to the mechanism . That said , use the RAM as a cache to speed up some data processing is not silly and others have done this journey recently. Only real constraint , which must be borne in mind, activate the RAPID mode passes data in RAM and in case of power failure , the Pavilion G7 data will not have time to travel to the NAND flash SSD will be lost. A risk not to underestimate .

      About price

      Still, on the whole, Samsung book with 840 EVO SSD based TLC finally frequentable . We must now see if their prices are attractive enough to warrant our attention. They were officially launched at prices slightly lower than 840 " tout court " on the market, 840 EVO 250GB is finally around € 160 , while 840 of the same capacity is today around 145 € . It is clear that between these two models, the price difference is justified by the

      HP Envy 17Tperformance and the latest firmware. But what is it facing a good MLC SSD ? A Pro 840 256GB buys new € 200 , a Corsair Neutron GTX € 210 and € 225 OCZ Vector . So, the 840 EVO TLC ultimately a good deal? Well, not necessarily if one chooses to oppose the MLC drives a less efficient but less expensive hair like Crucial M500 (140 € to 240 GB) SanDisk Ultra Plus (140 € to 256 GB ) , both based on of MLC NAND flash . And the situation is unfortunately the same for those seeking very large Latitude E5520  capacity , since the Crucial M500 960GB is around 500 € (0.52 € per GB) , while the 840 EVO 1TB is available at around 555 € (0.56 € per GB). We therefore conclude by saying that the 840 EVO is an amazing SSD in many ways that Samsung shows with him that we can offer good SSD TLC memory requirement of maximizing its firmware and develop adequate tools, but that ' choosing this type of memory , we expect the Korean manufacturer to do a little better on the price ...

    • Test: Samsung Galaxy S4 mini

      You have probably figured out by reading this test: the S4 Galaxy mini is halfway between the middle and high-end, opting for dimensions collected, but flawless ergonomics, performance and much more in line with a price that we can nevertheless help to find a high hair. At 100 euros less, the new XPS M1330 smartphone from Samsung was a case not to be missed. But, with between 400 and 450 €, the user is faced with a dilemma as price, for the same price or cheaper, it can also provide a Nexus 4 or Galaxy S3 which is still largely the cover. That said, if you appreciate the design of the Galaxy S4 but you want however acquire a little more compact smartphone without you focus on raw performance, S4 mini might be the one you want.


      Next one now as precise as a Swiss watch schedule, Samsung is not his last new Galaxy S in various formats for different uses. Last year, the S3 was entitled to an unconvincing "mini" version, as too limited by its performance at a high price. This year's mini S4 is always sold as expensive, but seems much more solid hardware side.

      Before confirming or not the HP G42  performance of the device, let us for a moment on its form, which will not surprise many people. If two weeks ago, we compared the Galaxy Mega a giant S4, mini, he is a S4 ... compact (what a surprise). More seriously, maintaining the same reference design and the same materials, Samsung once again takes little risk, but the result is ultra efficient. Mini S4 is indeed a model of ergonomics and fits perfectly in your hands.

      Its small size helps to give him a round and smooth, roller limit, which makes it very pleasant to the touch, while being a very safe grip. The Latitude E6400 screen edges are also very thin, but prior to a little less than the S4, and the thickness is in turn slightly larger than 1mm. For the rest, everything is exactly the same, whether the connection, location (perfect) of the ignition button and volume, the rear plastic shell, aluminum edges .... If you already enjoy the design of the S4, it will be hard to fault anything in its mini version. But the reverse is also true and allergic to the aspect of "all plastic" again sulk unit.

      The display, meanwhile, is largely worthy of what is expected of a smartphone Galaxy range. Eternal Super AMOLED meets once more present, and adapts well to the 4.3'' diagonal and the definition of 540 x 960 pixels. The HP G6 Battery colors and contrast are good, faultless vision angles, deep blacks and sufficient maximum brightness for comfortable use in direct sunlight. In short, a real highlight, which allows (only partially) justify the relatively high price of the device.

      Another pleasant surprise: the camera. If we do not reach the level of excellence S4 (clearly the better camera market with the Lumia 925), the 8 megapixel sensor with a LED flash is doing very well, especially on pictures taken indoors and low light. Outside, the Dell Inspiron 1525 result is a bit more mixed, with colors not always true and a slight overexposure. Anyway, for this format smarpthone, we are dealing with a camera with a very good level.

      A performance / price criticism?

      Autonomy is also one of its strengths and the unit can even be found on our podium duration of video playback (720p, wifi on, brightness at max), just behind the Galaxy S4 and Galaxy Note II. Constant at Samsung, which is long past master in the art of managing the HP Pavilion dv6000 battery(which is here 8800mAh). On a daily basis, so you can count on almost two days of traditional use, or a full day if you play the game and consume a lot of data. In short, this aspect of the smartphone is, again, blameless.

      Let us recall now the most critical of the Galaxy S4 mini aspect, namely its power / money. Last year, we were treated to a mini S3 with performance at a discount, which allowed even less swift than Galaxy S2, for a selling price around 400 €. A few months later, Samsung he made the same mistake? The first observation is the most obvious: yes, the S4 mini is expensive for a smartphone running Android 4.3''. At almost € 450 the

      Latitude E6420 machine, so we would expect such a perfect and versatile user experience.

      Do not worry: although contrast, the balance is very positive. Our benchmarks show indeed very respectable scores, not far from that offer smarpthone more upscale, located in the range of € 500-600. Only the result in 3D Mark is a little frown, which is also felt in the practice of recent 3D games, regular victims of nasty jerks. The rest is very fluid against: videos in HD and Full HD reads carefree (oddly, using MX Player lets appear a little lag while BS Player works perfectly) and navigating within the TouchWiz interface is impeccable. The consultation Inspiron 1545 web page does not pose a problem, except that related to the relatively small size of the screen, which means that we are often forced to move his thumb to read correctly.

    • Test: Asus FonePad

      TAGS: Dell XPS M1530PA3534U-1BAS, CQ62 Battery

      Unveiled in February at the Mobile World Congress in Barcelona, ​​the FonePad Asus was a product that was expected with curiosity, even a certain impatience. Indeed, despite its low-cost tariff, it seems very attractive on paper, is paying the luxury to offer an unexpected phone function. Remains to be seen what role it can have in our daily lives ...

      Let it be said: 2013 is the year of phablette,Dell Inspiron 1545  this new kind of mobile devices halfway between the smartphone and the tablet with a comfortable screen size. And if the Samsung Galaxy Note has pioneered a moment ago, many manufacturers have since stepped into the breach, pushing a little more reasonable limits on size. Huawei introduced at the beginning of the year of 6.1'' smartphone, Samsung offers Galaxy Mega 6.3'', but it is Asus, which wins the prize with this FonePad 7''. The same format as a Dell E4300 Battery , so, so much so that one wonders if it is reasonable to continue to be considered a phablette. Moreover, the editorial 'of PCworld, the debate rages: is a tablet that is also a phone, or a smartphone that can be used as a tablet? Both say that the disagreement was settled in sweat and blood, finally settled on this conclusion: the Asus FonePad is primarily a tablet which may serve as a phone, and that's a good thing because you will see, this aspect is not really his forte.

      But proceed by step and start with scanning the device in all its glory. By far the FonePad largely resembles a Nexus 7 and, more generally, to most tablet 7'' that have flooded the  XPS M1330 market in recent months rather broad black stripes on the sides, no physical button on the front, and only the presence of a microphone on the top of its role betrayed phone. At the back, however, it is further away from the Google tablet (also manufactured by Asus, do not forget), with an aluminum shell and a fairly smooth rubber cover housing slots for SIM cards and microSD. Despite appearances, it is also easily removed, since just drag two inches above to pop out of its notches.

      Unlike the Nexus 7, also the volume buttons and plugs are keyed to the left of the device, which is much more easily accessible. The E4310 Battery connection is meanwhile in minimalism, with a micro-USB port for charging and a jack, both located in the lower part of the device, which, for the use of a helmet is enough impractical. In this regard, the FonePad comes with in-ear headphones good surprise for rendering the music and hands-free kit simple and effective function. Side finish and build quality, nothing to complain, everything is impeccably assembled and exudes strength. However, the very 'slippery' of the casing prevents perfect grip and it was always a little afraid to let go when the catch with one hand.

      Better than Nexus 7?

      Call to screen this FonePad which, unsurprisingly again, quality is quite similar to that found on the Nexus 7. Based on an IPS LCD capacitive, the HP G32  manufacturer chooses the same definition (1280x800) and a pixel density equivalent (216ppi). In practice, visual comfort is ok but not great: viewing angles are good, but not exceptional, and the maximum brightness setting is a little low, unless you turn the "outdoor" mode in the settings. By screen tablets side by side two, however, we see white yellow pulling on FonePad and more generally, a little duller colors. It says nothing insurmountable, and it remains in the top quality average in this price category.

      Side autonomy, FonePad also pleasantly surprised: the Pavilion G4  battery offers ten hours of use with WiFi on, and reaches nearly 8 hours of video playback, which places it directly in the first place our comparison in the category of tablets 7 and 8 inches.

      Now let us get to the heart of the FonePad: its performance and everyday use. Next benchmark, it is, again, a good average, given its size and price, and shows consistent results with the hardware it offers. In use, the Intel Atom Z2420 1.2 Ghz processor, Pavilion G7 PowerVR SGX540 GPU and do the job in most cases and can benefit from a fast and fluid navigation within the interface, and an honorable comfort on 3D games. Again, you can expect something similar to that offered a Nexus 7 and Tegra 3 SoC, even if, on paper, our benchmarks show a net benefit to the machine stamped Google.

      Especially as the Jelly Bean Android 4.1.2 version used here is very customized and just allow some proprietary applications without interest (taking notes, slideshow creation ...), or the ability to superimpose a widget (calculator, calendar, stopwatch ...) transparency of any screen. Functionally equivalent to that found on the LG Optimus G. Briefly, the OS appears light and pleasant to use.

      Conclude with what remains the most subjective to assess point but we will still try to judge: the phone part. Much to say right now, the format 7'' seems to us clearly too large to be effective through use of conventional telephony, that is to say, the HP Envy 17T device glued to his ear. Too large in the hand and in the pocket, it may eventually find its way into a bag or briefcase, but quickly sentenced to be used with a handsfree. To summarize: it can act as a secondary phone perfect for the home, on a table, but certainly not the main smartphone, unless you are ready to use it only with a headset.

      The Asus FonePad is therefore not a revolutionary Latitude E5520  product and is positioned primarily as a good tablet 7'', which may serve as a phone in a particular context. However, it keeps the price argument, since it can be found for less than € 229. For this price, so you are entitled to a good clone of the Nexus 7 3G version, which also offers a microSD slot and a longer battery life, which is already very good.

    • Test: Galaxy Note 8.0

      Tags: Dell studio 1558 ,  E6500 Battery , Dell XPS M1330

      Announced at the last Mobile World Congress, Note 8.0 is the new version of the Samsung range stylus. Really a smartphone, this large-format Note further attack 8'' tablet market with line of sight one competitor in particular: the iPad Mini.

      In addition to its unique size in Samsung - who typed so far in the 7 or 10'' - Note 8 was at the time of its announcement, makes sense, thanks to the  PA3258U-1BAS possibility to use it as a phone. However, if you paste the idea of ​​such a device to the ear you bristling hair, do not worry: the only version currently available is equipped with WiFi only, and it is also one that makes the The purpose of this test. First observation, when captured for the first time the Galaxy Note 8.0: it is pure Samsung in design. Kinship with the Note II or the Galaxy S III is obvious here, even if the screen edges are wider than usual ...

      The whole is always cast in a smooth, glossy plastic shell, which seems quite slippery at first, but that it has an impact on the grip in practice. Close to the mini iPad in its format, Note 8.0 is slightly larger, thicker and heavier. However, it is the VGP-BPS12 impression of lightness and solidity which predominate, confirming that the size 8'' seems to be an ideal compromise between appearance "16: 9" with a 7'' and the larger size of 10''.

      Problematic stylus?

      The connectivity and the location of the buttons are for their impeccable. It has quick access to micro-SD slot, volume buttons fall well under the fingers and the case to store the stylus / S-Pen (in the lower right corner as shown in the Note II) is both discreet and easy access. On this last point, however, we found a rather annoying problem: the  Battery  VGP-BPS9 extreme sensitivity of the recognition of the "withdrawal" of the S-Pen. Simply, most of the time, seize the tablet for it erroneously detects an output of the stylus from its location, automatically causing the output unit to standby. The screen changes suddenly its time to turn without being asked anything. Unclear whether this defect is specific to the SONY VGP-BPS8 device that was provided to us or if it is a simple software bug that will be a future update .... In contrast, the S-Pen itself is very pleasant to use, accurate and ergonomic. The comfort provided by the screen 8'' is not a stranger, and taking notes "in pencil" takes on a whole new dimension.

      To screen its first tablet 8 ", Samsung has chosen a TFT capacitive display offering a resolution of 1280x800 pixels and a density of 189 ppi. Keeping with its policy, the Korean manufacturer and foremost on brightness and color and a very marked contrast, even lose a little fidelity. If Pavilion DV6 more demanding in terms of rendering will be always a little disappointed, hard to complain against the clarity and accuracy of the the Samsung screens have not much to prove this point.

      Autonomy, in turn, is somewhat disappointing, especially compared to the excellent performance of the iPad mini. But not catastrophic, the quality of the DV5 Battery (5200mAh, yet) allow you to use it from one day to a day and a half. This result largely down during video playback (WiFi on, maximum brightness) as our test shows a shy 5:30, barely more than a Nexus Nexus 7 and less than 10, which were already quite down our comparison chart. However, the management of standby looks good, the battery level dropping to only a few% in 24h.

      At the top of the podium performance

      Although this is not the first argument of a tablet, the quality of the  HP Pavilion DV4  is always more important. Here, the surprise is quite good, since the 5-megapixel sensor offers outdoor photos pretty successful, offering accurate colors and satisfactory accuracy. No flash on the other hand, which immediately eliminates any possibility to take pictures in low light, the sensor is not big enough to support a context too shaded.

      With a score of 17093 in AnTuTu Benchmark and 46.4 fps sources Epic Citadel, the Galaxy Note 8 is placed directly on the podium of the best performing market shelves, even monopolizing the top spot on AnTuTu. The four heart Exynos processor clocked at 1.6 Ghz worked wonders, as the Mali 400MP GPU. The user experience is all the better, the fluidity of the interface is rarely faulted, and playing flawless multimedia files. It's simple, in terms of HP 484170-001 raw performance, Note 8 seems to be what is currently the best in the segment of tablets 7-8 inches. Also nothing to complain about his part: the speakers are in the average and offer proper sound power (even if it still should not expect miracles on a tablet of this size). As for the sound output from the headphones, it is true, and no pronounced deformation.

      Ideal for taking notes

      One of the main arguments of the range rating is of course the famous S-Pen, which is accompanied by a battery of applications dedicated to note-taking, drawing and other scribblings. On this point, fans will be so filled with sketches, the unit covering almost all needs in this area. You can create a travel via "Journal", lay out a personalized magazine with "Magazine", create greeting cards, take "raw" notes, etc.. Handwriting is nice, and the stylus to draw quite accurately, the pressure on the screen is taken into account. If we are still far from the quality of a professional pen (as found in Wacom, for example), we can only applaud the compaq presario cq60 quality level offered by Samsung for a consumer product.

      But the penguins pen reassure the Galaxy Note 8 may well be used "finger" and echo the principles of TouchWiz, found especially on the Galaxy SIII or Note II interface. No big surprises on this, so this fit perfectly overlay format 8''. If you are used laptop  XPS M1210 products, so you do not risk being homesick. Note that the windowing, function already present on the Note II (which allows you to view two applications at the same time, one on each side of the screen) wins again here in interest and comfort.

      Finally, and not surprisingly, the Galaxy Note 8.0 proves a very good tablet 8'': powerful, comfortable to use and ideal when it comes to taking notes or view content. Slight defects mentioned above are not disadvantageous, however, hoping that the bug recognition pen is only very temporary. Dell Inspiron 1300 remains to address the issue of price: € 399 in the WiFi version, it clearly is at a rate that could put off those who want to acquire a "small" tablet to a consistent price. A little more expensive than the iPad Mini and more than the Nexus 7, the Galaxy Note 8, despite these undeniable qualities could be difficult to justify the pricing of these few hardware improvements. A reflection will however not unduly started our overall opinion: we stayed in love with this new Samsung tablet.

    • Test: OCZ Vertex 3.20

      Tags:  HP G6 Battery,  G7 Battery, HP Envy 17T

      OCZ now offers shops stamped his latest SSD Vertex 3.20. Beyond simple index change, what are the changes from the model 3.0? Is it as Dell Studio 1558 effective? And at what price?

      Since he decided in 2011 to invest the SSD market, OCZ multiplies the good things, like recently with the very grand entrance of his latest disc called NAND Flash Vector (see our test here ). However, on the sidelines of the launch of new products, the American company has not forgotten its ancient references provided, it continues to improve in small steps. This is now the case of Vertex 3, which is adorned with a new 3.20 index winner in passing some interesting Dell Inspiron 1545 fonctionnnalités.

      And contrary to what is usually done, this renumbering owes nothing to chance. The number "20" in fact refers to the fineness of engraving that characterizes the new NAND Flash chips (Intel MLC) required for data storage. For the record, these are the same chips found in the Intel 335 Series products, and we had the opportunity to evaluate in a previous test. And as things are done well, the Intel and OCZ SSDs have the same controller, namely a LSI SandForce SF-2281.

      However, let's be clear: if the  Dell E4300 Battery internal specifications leave hope for the best performance side, the packaging is meanwhile more minimalist, comprising only the disk without cables or hardware.

      A renewal is good?

      The side of the storage size, there is no particular distinguish change from version 3.0 of the range. OCZ still has two disks, one 120GB and the other 240GB, with, as you can see in the table below, the  XPS M1330 performance in sequential mode are identical. However, in random disk access is a bit different, for writing 4K block. Of course, these results provided by OCZ are shown on compressible data, on which the SF-2281 controller excels.

      Not surprisingly, these are the numbers we decided to check first. Crystal Disk Mark with software that generates incompressible data, obtained some much the same IOPS performance. On the one hand, the

       Dell E4310 Battery test back 35,087 IOPS random 4K block read and 64,575 IOPS for writing the same data type.

      On the ATTO test, which in turn generates highly compressible data, the speed is a little slower than expected, but it still remains on good performance with 539 MB / s sequential read and 514 MB / s sequential write. With the  HP G42 Battery test suite from Futuremark PCMark 7, the Vertex 3.20 offers the luxury of dropping directly in 6th place in the standings with 5278 points. Stronger yet, it moves just one point and even Samsung 830 passes over the last Sandisk SSD, the Ultra Plus 256 GB

      As for pricing chosen, the gain is significant compared to the previous generation. Compare our price, OCZ Vertex 3.20 shows a price of € 0.69 per GB. A comparison with the same SSD in the Intel HP G4 Battery  brand that appears to € 0.76 GB, OCZ drive is cheaper. In so doing, our performance index / price, it takes the fifth place on the all SSD passed through our hands. Undeniably, the consumer has won everything in this update, even if the software side still deserves some optimizations, Intel seems to have been carried out on its own SSD.

      HP SpectreXT TouchSmart: a large touch ultrabook for home
      This laptop PC ultrabook-screen 15.6 tactile inches is one of the flagships of the new HP range. Well finished and solidly equipped however, it is a little imposing and lack of endurance for you accompany everywhere.

      the promise

      HP unveils a new ultrabook, the SpectreXT TouchSmart 15-4000fr. Only available on the online shop of the

      HP Pavilion DV6  manufacturer, to nearly 1400 euros, this machine equipped a touch screen of 15.6 inches is clearly positioned in upscale and equipped accordingly. Move to test.


      Le Spectre XT TouchSmart is beautiful and well equipped. The first contact with this Pavilion DV5 Notebook PC, which mixes brushed on top and magnesium silvery on the underside alu, is pleasant. Ranked in the family of ultrabooks, this Spectre XT is equipped with a screen 15.6 inch diagonal (39.62 cm). It displays beautiful images in high definition (1920 by 1080 pixels) and integrates a slab touchscreen that, associated with the very good keyboard backlit (without numeric keypad) and the general touchpad, facilitates the piloting of Windows 8.

      A little heavy (2.2 kg) and thick (2.5 cm), this DV4 laptop PC HP did "of ultrabook» that its components. They consume and heat little but are powerful enough to rotate all applications, games set apart. However the machine sinneth by a too short autonomy: only 3 hours in video playback. His endurance and its format therefore do not make of SpectreXT TouchSmart a large nomadic but rather an occasional traveler, which finds more its place in the office than in the backpack.

      Software and sound

      HP 484170-001  preinstalls good software in full version on this ultrabook imposing. Norton Internet Security 2013 with two years update for security, Adobe Photoshop Elements and Premiere Elements 10 for photo and video works or yet CyberLink PowerDVD 10 the reading of films. For the audio portion, HP always setting on pregnant and the signed audio Beats by Dr. Dre software, rendering correct.

      Good components and of Thunderbolt

      So that the SpectreXT TouchSmart meets the finger and the eye under Windows 8, HP retains an Intel (Intel Core i5-3317U, double heart clocked at 1,7 Ghz) processor latest generation supported by 4 GB memory and a module SSD of 256 GB of the machine. No engraver DVD, by against, and no way to enjoy the last 3D games. The video circuit of SpectreXT,  compaq presario cq60 integrated at Intel processor, is not powerful enough for that. To complete the equipment, HP garnishes the flanks of the machine a game of complete taken composed of taken USB 2, USB 3, of a network jack and HDMI and miniDisplayPort video outputs. This last is combined with of Thunderbolt. Finally, the wireless is of the part with Wi-Fi n and Bluetooth 4.0.

      the verdict

      The SpectreXT TouchSmart 15-4000ef of HP is a ultrabook imposing but well finished. One appreciates all installed software full version on delivery and quality of the touchscreen. Its price we seems globally justified if it is only the Dell XPS M1210 device sinneth by its autonomy a fair bit.

    • MSI Z77A-G45 GAMING


      MSI is trying to compete with high-end motherboards "ROG" from Asus and "FTW" EVGA presenting the Z77A-G45 Gaming. The Z77A-G45 GAMING allows MSI to redo makeover on a platform based on Intel compatible socket 1155 processors. This time, Inspiron 1526 swapped the black and blue to follow the trend: black and red.

      To give them a little "pep", the "Gaming" versions borrow the virtues of dragon decorating so the chipset heatsink and borrowing aesthetics scales of the beast for those power levels.


      The chipset used is the Intel Z77 perpetual support for SATA 6Gbps storage devices and USB 3.0 natively.

      To complete this offer, the Z77A-G45 GAMING favors multi GPU solutions with Lucid Virtu MVP and CrossfireX or SLI. Sound like the Pavilion DV4 network are key elements for gamers and that is why we find the "Killer Ethernet" feature to limit the effects of downturns but also "Sound Blaster Cinema" to provide a more realistic sound.

      To ensure a long and infallible reliability, MSI has once again components "Military Class III".


      Finally OC Genie II overclocking significantly simplifies the procedures and "Total Fan Control" allows precise control of fans dedicated to the cooling components. If offered such a comprehensive and attractive map as it is an excellent initiative that we welcome, she remains a good choice for players knowing that the release of the next generation of Compaq Presario CQ60 processors "Haswell" is imminent?



      MSI was able to offer many motherboards for Intel platforms with a very good value for money. For example, the Z77IA E53 mini-ITX had shown itself particularly convincing. Although Intel is expected soon to announce the availability of its new generation of processors "Haswell", MSI takes the risk of proposing yet another collection dedicated to families "Sandy Bridge" and "Ivy Bridge." The Latitude E6500 manufacturer was indeed slightly behind the high-end segment usually reserved for overclockers as well as the only players represented by the "Power" collection. It therefore welcomes the efforts made by the manufacturer hoping that the result is convincing.

      Thus the new motherboards "Gaming" MSI differ primarily on an aesthetic level, but also on-board equipment. It consists of four models, including three equipped with Intel Z77 chipset. Only B75A-G43 Gaming stands with B75 release. The Toshiba PA3465U-1BRS nuances between the various references are minimal.


      They focus on cooling the floors of food, the type of components, the multi GPU and SATA interfaces support. It thus replaces the blue card by red more in tune with current trends and new features are introduced. But first the main features of the Z77A-G45 GAMING. We discover a map to shipping size ATX socket 1155 ccompanied by a famous last Z77.Ce chipset Intel warrants the media to the fastest SATA 6Gbps standard, USB 3.0 and various features such as Intel Smart Response Inspiron 1300 Technology, Rapid Start and Rapid Connect.


      We also have 24 PCI Express lanes allowing the accumulation of several unlimited bandwidth with support for PCI Express 3.0 graphics cards. Getting closer now embedded on the Z77A-G45 GAMING it will stand out from the competition equipment. First Killer E2200 Ethernet Controller will reduce latency occurring in online games. A particularly complete application is proposed to make the most out of this tool. The audio is also another major concern of the players, the DV5 Battery  GAMING enjoys "Sound Blaster Cinema", an application enhancing the sound carries in games.


      Finally always to achieve the best scores, two USB ports are switchable in 500 or 1000Hz to increase the reactivity of mice and keyboards. The Z77A-G45 GAMING is compatible with CrossFire and SLI. We can therefore combine the graphics card and MSI adds Lucid Virtu MVP, well known to increase framerates for example by adding computing power of the VGP-BPS8 processor IGP integrated 3D graphics application. Last trump the Z77A-G45 GAMING which has certified "Military Class III" with better overclocking potential, an advanced level of reliability as well as improved stability selected components.



      Purified, it evokes the Z77A-G45 GAMING at first contact. Its classic black PCB seems stripped of components as they seem few. It is clear qu'MSI employs more integrated circuits leading to such results altogether convincing. Failing foolishly copy its close competitors, the Inspiron 1525 manufacturer drops the bright red for a little more Asian and therefore closer to the purple alternative. These are the radiators chipset and the power stages involved. The first features a dragon that is largely prefer to rounds of ammunition have met on other competing models.


      The second radiators have the right to a perfect finish and design evoke the scales of the animal. They are divided into two blocks and are responsible for six VRM cooling. The Z77A-G45 GAMING 1155 features a socket permanently placed in the first half while the four ports will DIMM RAM. Let's get right to the bottom half of the Z77A-G45 GAMING on which there are three PCI Express x16 and four PCI Express x1 ports.


      Below still on the edge, the deportees connectors show no originality like 99% of motherboards on the market.

      Inspect the mismatched six SATA connectors. We would have preferred that those compatible with the third revision of the Pavilion DV6 standard differ only in color rather than their appearance. By cons MSI is well opting for remote USB 3.0 finally bent. Above the voltage measurement points are used to place a voltmeter. A mother "Overclocking" card is necessary, but on a "Gaming", the choice is debatable. Finally on the rear panel, the offer is complete with a PS / 2, four USB 2.0, two switchable in 500 or 1000Hz, a Clear CMOS switch, an obsolete digital coaxial output, S / PDIF, two USB 3.0, ethernet three video outputs VGA, DVI and HDMI, and finally six mini audio jack.


      On the bundle, if efforts are made on those graphics cards with many games, some brands of motherboards MSI which part should shake a little more to offer than two SATA cables, a rear panel, a CD-ROM and various paper documents. When will real useful software (antivirus, ect) and not mere trial versions, groundwater quality and in sufficient numbers and adapters? Although the Dell Inspiron 6000  is not the more upscale but greatly help users to finalize their choice. In all cases, the Z77A-G45 GAMING offers an original and compelling successful aesthetic. It will delight those for whom the look is important.



      The BIOS of the Z77A-G45 GAMING being at exactly the same features than the Z77A-G45, we adapt dedicated to this new revision because only aesthetic change section. Evolved through backup features on USB key, it uses colors pleasing to the eye even if you wonder why the six menus arranged around the main window are also great. It would have been interesting to optimize the E6410 battery display by minimizing these huge buttons clickable. Moreover, if all the ingredients for a current BIOS options are present, we can hardly say that it is convenient to use and ergonomic.

      Six sections therefore call on the Z77A-GD65 GAMING:


      You should know that to use the alternative OS MSI, it is necessary first to make a removable storage medium that shipping system. The  HP 484170-001 Settings menu contains the basic options such as embedded devices but also the unique technologies of the Intel Z77 chipset and Z77A-GD65 GAMING as LucidVirtu. The options are clear and legible and UEFI BIOS of the motherboard supports multi language. The integrated help supposed to explain the different options could be more comprehensive and clear.


      Overclocking the menu will push its processor in the last corner because all parameters are present: adjustment ratio of PLL voltages, the BCLK and many others. The RAM can also benefit from custom parameters such as voltage, frequency or CAS. Each specific processor features are grouped into a second menu and caters to the most strenuous overclockers. They allow the intervention parameters of the more sharp the CPU power. Finally, the Latitude E6510  possibilities for updating are simple, practical and effective. It only takes a few seconds to receive the latest UEFI BIOS of the Z77A-GD65 GAMING.



      In recent months, MSI has undertaken a real effort to provide modern applications facilitating the setting and monitoring of its products. On the Z77A-G45 GAMING three major software package stand included with the card: Control Center II, Click BIOS II and Killer Network Manager. Start with Control Center II has a makeover in good and due form for this specific range. We thus find the colors now associated with this category.

      The HP Pavilion DV2000 options remain faithful to the "Performance" series from MSI. Menu are essential tools related to overclocking, the ventilation management or control via mobile device.


      The "Overclocking" tab includes all the necessary options to increase the frequency of the CPU and RAM as even the IGP. Tensions and other factors can be adjusted without the need to use the BIOS. The second menu will be responsible for automating overclocking the Dell Latitude e6400 processor as quickly as possible. This will prevent such beginners to have absorb technology but also terms may be too technical. The biggest advantage of this solution is especially not to take any risk to the health of the equipment where every wrong setting can be fatal if not properly characterized. The third tab is dedicated to the management of the fans. The Z77A-G45 GAMING manage up to three profiles including that of the processor. We especially appreciate this tool as the beaches of thermoregulation are important.


      Can benefit from a silent operation at rest but also to enjoy a cooling more efficient in operation. Of course it is imperative to use appropriate fans and assemble the PC correctly to exploit its full potential. The last tab to activate need map control via smartphone or tablet. An option beyond the scope of this test. Active LED tab or off at will the LED on the power stage. These are at the top of the Dell Vostro 1510  and this option will allow purists precisely control the lighting of their machine.


      Click BIOS II is a very interesting application conceptually speaking, as it allows changing the BIOS settings directly from the operating system. But in practice, Click BIOS II is largely improvable for two reasons:

      Click BIOS II suffers from a painfully slow and a discouraging response. Furthermore any changes will restart the Sony VGP-BPS12 machine. Last detail of lesser importance, MSI has not seen fit to harmonize aesthetically Click BIOS II with Control Center II. This leaves an impression of oddity marketing rushed. Unsurprisingly, Killer Network Manager is a simplified application management QoS (Quality of Service). It would merely eg prioritization between voice and data.


      We also emphasize responsible for MSI Live Update automatically download and install the BIOS, drivers and applications automatically. Failing to integrate the latest drivers, it keeps the advantage of simplifying and accelerating this daunting task.


      Performance games

       3DMark Cloud Gate

      Futuremark, the famous editor of the benchmark benchmark dedicated graphics cards: 3DMark 2011 offers a new version that includes three sets of tests: Ice Storm, Cloud Gate and Fire Strike. The first is reserved for DirectX 9, we do not include in our test. Cloud Gate is designed for platforms "performance" focusing on Post Processing effects and particle effects. A second sequence is for volumetric lighting but using a low level of geometry. The Dell Studio 1558 test of Cloud Gate simulates physical effects of rigid and deformable objects.

      Virtu MVP saves a few hundred points with Lucid Virtu.


       3DMark Fire Strike

      Second test includes the new 3DMark Firestrike addresses the most powerful configurations. It offers too heavy tessellation effects and complex smoke effects. We execute Fire Strike in extreme version.

      Same conclusion with Cloud Gate but with a much smaller gap. Far mode, we find the behavior of 3DMark 11 where the VGP-BPS14  boost is much more comfortable when testing heavy computing power. After his release, Metro 2033 has put many graphics cards on the knees partly due to effects requiring significant computing resources. We use the DirectX 11 API to benefit from the latest innovations in visual effects.

      For each resolution used, we always use three distinct levels of details:

      Low: quality "Low" anti aliasing "NOAA" and texture filtering to 4.
      Intermediate: quality "Medium" anti aliasing "AAx4" and texture filtering to 4.
      High: quality "Very High" anti aliasing "AAX8" and texture filtering on 16.

      Under Metro, the Dell Studio 1555 motherboard fully exploit our graphics card.



      Do we have to face facts, the motherboard MSI Z77A-G45 GAMING Z77A-G45 is a slightly improved. Besides aesthetic tidy, there are adding new features like Killer E2200 Ethernet for network and Sound Blaster Cinema for audio. But these few upgrades are far from essential and will be rare to find an uncompromising real Latitude d830 performance gain or comfort game players


      While the MSI Z77A-G45 GAMING has undeniable quality finish and will be quick and powerful center of a PC. Even if the BIOS limits the maximum CPU voltage to 1.52V which thwart the fierce overclockers, it remains more than enough to make the most of the installed processor.

      The graphical overhaul BIOS as the Control Center II in line with the design of the card brings a welcome revival. Click BIOS II damage that does not benefit. These Latitude d630 applications are still compelling, practical and effective. We also liked the strategy that MSI Gaming developing its collection enriches its product in a clear and relevant.


      If the choice of the additional equipment used is still debatable, we remain positive because it is the first generation that has to mature to compete with the ASUS ROG series or Asrock Fatality. Ultimately, it is mainly the price of the MSI Z77A-G45 GAMING tainting its release. Proposed for about 150 euros, it will be a lot of trouble convincing facing the Dell Vostro 1520 gaming version not available for only one hundred dollars. In other words, Killer Ethernet, Sound Blaster Cinema and Lucid Virtu MVP increase the rate of one-third or more than 30%. The bill is so salty for even a dragon growth phase and we hope that the MSI Z77A-G65 GAMING more upscale will show a much better value for money.

    • Test: LG Optimus G

      Tags: studio 1555, Latitude E6500, XPS M1330

      After Sony and HTC, it was the turn of LG released in France's new high-end smartphone. An efficient and well finished XPS M1210 product, but apparently sharing many similarities with the Nexus 4, for a higher price.

      Output outside Europe in November, and at the same time as the Nexus 4, the LG Optimus G is only available from us since March in an oscillating between 500 and 550 € price. This price puts it directly into the "low" high-end smartphone range, where he met the Sony Xperia Z, HTC One and of course the Galaxy S4. At the reading of his characteristics, however, does not fail to note a number of commonalities rather disturbing with the Nexus 4: same size and resolution screen, same processor, same GPU, same amount of RAM ... Until his shell glass, which immediately recalls the takeover of the smartphone Google. Nothing too surprising, however, since the Nexus 4 was also designed by LG. We can then ask the question of what really differentiates the two devices to share the prize.

      First observation: the Optimus G is beautiful, just as it is simple and classic in design. We said, it shares the same back cover glass as the Nexus 4, but adopts a slightly more straight edges, for a result that is more reminiscent of the  HP 484170-001. However, if the grip is very nice, it is a bit slippery due to the corners a little more rounded. That being said, and more generally, the finish of the Optimus G exudes quality and high-end: the buttons are perfectly placed, the metal strapping around the screen adds a touch of extra shine and only two screws visible in the lower part with a little swear all.

      A perfect screen, a range in the average

      The front screen of 4.7'' inch True HD IPS provides a definition of 1280x768, is reinforced by a Gorilla Glass 2, and seems excellent craftsmanship. In addition, it displays a very satisfactory brightness, accurate color (not too saturated or too dull) and a fine flawless display. Coupled with the Pavilion DV4 excellent responsiveness of the OS (we will), we obtain here a view of a very convincing quality.

      Autonomy, meanwhile, is in the middle, slightly higher than what is usually found in this class of devices. The

      DV5 Battery will probably not reach the peaks, but its life varies greatly depending on the use you make of the smartphone. Video playback, for example, the Optimus G is on a par with the Lumia 920, but is a notch below a Xperia Z. As part of a more conventional use (call, email, sms, surfing), can however count on a lifetime approaching the big day, plus night. A rather positive finding, then. A strange thing is however to note: sometimes the brightness crashes, especially when the unit heats up too much, and it is necessary to wait a few minutes before being again able to change this setting .

      Correct APN, without

      No real fault for the moment, the LG Optimus G manage to be as convincing as regards his camera? Equipped with a 13 megapixel sensor (a value that becomes the norm on smartphones in this category), the AFN has pictures of good quality, without reaching qualitative heights. Compared to the Nexus 4, the

      HP Pavilion DV6 performance is more or less the same, despite the 8 megapixel camera of the latter. Outside, the record is pretty good, but with a little overexposure and this rendering sometimes dull colors.

      In low light, the pictures are pretty convincing, despite a flash that tends to make the picture quite cold. Side finally capture video (up to 1080p), the camera betrays an update moderately responsive autofocus. Note the addition of a few widgets friendly (but already seen) as the SONY VGP-BPS8 deformation of real-time face or adding a decoration around a topic. Often unnecessary, but fun all the time ...

      Responsive and pleasant Android

      Let us recall now the overall performance of this phone, and the quality of the proposed everyday experience. If you followed, you already understand that the technical specifications stick very closely to those of the Nexus 4 ... Not surprisingly, therefore, the VGP-BPS9 performance is very good and the benchmark results are very close to those the Google phone, except on 3D Mark where Optimus is actually behind. All this leads to a reactivity without Android (version 4.1 here) fault, and impeccable fluidity, both when navigating the menus on the web.

      Side overlay, customization, called Optimus UI 3.0 is generally good taste, with some cosmetic in here and there effects: zoom effect when you unlock the  Toshiba PA3258U-1BAS screen is very successful, as the QSlide function which brings up an app 'overlay another. Rather well thought out, this system allows for example to receive an SMS and then answer that one is on a web page or a video. Fortunately Tie (window size, transparency, etc..), However, shows QSLIDE is sometimes a little too invasive and some may prefer to quickly return to the  Inspiron 1300 traditional system of notification in the top of the screen, clean Jelly Bean.

      Anyway, the overlay Optimus UI 3.0 is a very good surprise, since it embodies good taste not to slow down the OS while providing a interface finally close enough to the original Android Jelly Bean. Overall, it is also all of this LG smartphone that is a nice surprise with a high-end hardware, excellent performance, flawless finish and a 4G compatibility, it is difficult to find fault.

      Finally, the Dell studio 1558 biggest complaint that could oppose him would be his too much resemblance to the Nexus 4, for a higher price (April 16 GB Nexus is trading at € 349, the Optimus G 32 GB to 499 €) . The question is whether you prefer to wager on storage space (which is not expandable on both devices) and future 4G coverage in France (which is not forthcoming). Anyway, the LG Optimus G is undeniably one of high-end smartphones to be considered in a purchase decision.

    • Test: Fractal Design Newton 600W R3

      Tags: Dell Studio 1555, Latitude E6510,  E6420 batteries


      Fractal Design is not only Dell XPS M1530 PC cases. The Swedish company also provides power to put into it. With its new Newton R3 and 80Plus certification range, she hopes to make an impression. But these models are they really a good deal?

      After Tesla Integra R2 and R2, Fractal Design is now offering a new range of power supplies called Newton R3. We were able to spend a few days with the 600W model, which, like its peers, has an 80Plus Platinum certification, the highest award in this power category. Around this block we begin with the  PA3534U-1BAS cooling system of which 13,5 cm fan may operate in a semi-passive mode. More specifically, it does not take effect until the moment when the load exceeds 50%, or about 300W. Once started, it will continue to regulate its rotation in order to provide the minimum of noise, while meeting energy needs. A system that generally works wonders, since this block Newton R3 will be shown in an exemplary discretion, even more than 600W load.

      Side wiring, Fractal  CQ62 Battery Design offers everything you need in a bag that does not disown the hero of the series Dexter ... Inside, a PCI-Express cable doubled with two 6 +2 pin connectors, three SATA cables to cover a total of 9 HDD cable for Molex devices and Floppy Molex adapter. Note that all this a platform. The missing? Yes! This Newton R3 is semi-modular effect and offers cables ATX 20 +4 pin, the EPS ATX PCI-Express socket for the CPU 4 +4 pin, and a second cable doubled 6 +2 pin directly. The  Dell D630 Battery offer is so bloated, but not enough to hide a defect, however: some cables are too short, especially those intended for food or the graphics card. In fact, if you do not encounter problems on a small box, with a medium or large tower case, the case will be complicated, and the links will then be live, which singularly fail to aesthetics.

      Since we are talking about dimensions, it should be noted that this block Fractal Design has not done in the standard. If the Inspiron 1525 height and width are fixed and data to 8.6 cm and 15 cm respectively, the length by 16.5 cm. These dimensions are all the more strange that the modular connectors on the block does not seem to require much space. In addition, the interior block provided by the Taiwanese company ATNG is not particularly greedy on this aspect. We can therefore assume that Fractal Design has simply erred on the side of the 600W model. Always side connector block, modular cables have a little trouble returning. At least, once you have a little forced on the holding mechanism, the HP Pavilion DV6 cable will not risk moving.

      SLI and Crossfire

      Like its sister version 800 and 1000 W, 600 W R3 that Newton will dsponible in black or white, and benefit from an 80Plus Platinum certification. A certification that will not fly, because the official figures place it in the top of the basket over the E5500 batteries competition. At 20% load, it gets 91.41% yield while at 50% load, it goes up to 92.37%. The value drops to 89.45% to 100% load.

      And good news: these numbers are found on our test bench (see protocol). As expected, a little more than the 300W ventilation starts. But the cooling cycle under Fractal Design allows it to also turn off depending on the temperature inside the block. Another good point between each cycle, the Dell Vostro 1520 fan does not cause unpleasant noise as was the case on our Corsair GS800 power.

      Good but could do better ...

      Fractal Design HP Pavilion DV7 signs here a new range of high potential. With the help of circuits ATNG, this Newton R3 delivers easily the power you need, even for a dual GPU configuration. However, we must not forget to check the size of your case before you buy! Issue price, if you look over our competition on price comparison, this block Newton R3 600W is 10 € cheaper than the equivalent of 660W Seasonic. In all cases, Fractal Design comes in a good position on this power range. I bet that the Swedish firm quickly fix this glitch cable length.

    • Test: PC Power & Cooling Silencer Mk III

      Tags: Dell Inspiron 1525, Toshiba PA3465U-1BRS, DV4 Battery

      OCZ under the dell  PC Power & Cooling brand, has recently launched on the market a 750W 80Plus Gold power. If the brand is not really known yet, it could quickly surprise a ...

      Our test bench power is left in the depression after separating from his excellent Corsair AX760i, we had today offer a new product to be evaluated at least as attractive, just give him some colors. And this PC Power & Cooling Silencer Mk III Power 750W, 80Plus Gold certified, seemed quite up to the task. As we noted in the introduction, this Dell XPS M2010 brand is in fact a special branch from OCZ, and even going a bit further, we find that the components of this model numbered PPCMK3S750 are made from at Seasonic. Moreover, the presence of this control system home temperature with a hybrid mode, and a switch on the back, is the proof: this is a typical element of the Taiwanese brand .

      With this system, the power will go a Classic mode to silent mode, the latter allowing it to continue to operate with a minimum of noise, and up to 50% load (about 375W). After which the 14-cm fan will start up. Overall, we note that all offers Latitude d630 performance rather neat. Even at full speed, the fan remains discreet in not exceeding 36 dBA. To connect the components of our test configuration (see protocol), the Silencer Mk III has atypical connectors. After being inserted into the block, then it will tighten the connector with a thumbscrew to secure the wiring.

      Still on the connection, it should be noted that the small bag provided contains all necessary cables for a robust configuration with two graphics cards. Semi-modular fashion, this power supply offers more cable ATX motherboard 20 +4 pin ATX and EPS cables two 4 +4 pins, four PCI-Express 6 +2 pin, three cables with four SATA taken each cable Polex taken four and a Molex to Floppy adapter to finish. It added that all cables are supplied with a flat round base to start to get into the Sony VGP-BPS12 connectors on the power supply.

      However, these connectors are quite impressive in the diet, the dimensions of the block itself are all the more significant result compared to the competition. In fact, it measures 15 cm by 18 cm 8.6 cm, 2 cm or more. However, this system of fixing cables seems particularly robust and detail that does not spoil anything, it returns the feeling of a clean and tidy once finished editing box.

      Seasonic Inside ...

      Since the block is now installed and ready to deliver its full power, it's time to see what the active circuit Seasonic has signed in the stomach.

      On the one hand, the figures 80Plus body that issued the 80Plus Gold certification for this PPCMK3S750 with 89.04% at 20% load and 91.3% at 50% load and finally 89.08% 100 % filler with still a consumer level detected at 863.3 W to 769W to the Dell Vostro 1510 configuration taken EDF. From our side with two graphics cards running at full speed, the power consumed 671W on tap. A figure slightly above the Corsair AX760i that can be qualified by the actual performance between these two models.

      A good price / quality ratio

      What should we learn from this power end? First, the wiring system is interesting and gives a certain cachet to the configuration once installed. Then, ventilation is silent in 80% of the time. With a single graphics during game play card, it can even happen that the HP 484170-001  fan does not start-up. If the game engine is a little greedy, the fan blowing on the components of the diet will still remain discreet.

      With an entry ticket of around € 130, one might wonder if PPC does not ask too much. However, looking at the other items available on the market today, it is positioned well enough with a Seasonic circuit board. Moreover, if we look at the side of this Pavilion DV6  brand, it is around € 160 equivalent power. The PC Power & Cooling Silencer Mk III 750W is a good diet if you are close to putting a little money.
