Fermi - GTX 480 / GTX 470 PSU

[mauricio]

Today here I am going to provide you the most suitable power supply for GTX 480 and 470 card. So if you are going to buy a Fermi or GF100 series card to build up your own processor then you must also need to concentrate on the power supply you are using. Work is not finished just by adding the faster cpu and high rams. The fuel of the system also plays a major role for proper functioning of the entire system. A low or average can create serious overheating issue on your system destroying your hardware on Overclocking or SLI mode.

The GF100, the first incarnation of the architecture Fermi, has already been the subject of much discussion. We had already proposed two items that are returned in details in this architecture. Manufactured at TSMC in 40 nanometers, the GF100 includes over 3 billion transistors, NVIDIA is not more specific on this figure. With an area of 529 mm ² of the photos published a few days ago that (it is protected by a heat spreader), the GF100 would be a little smaller than the GT200, which was 576 mm ². This is still huge compared to 334 mm ² Cypress AMD and directly influences the production costs for Nvidia. Certainly, it fortunately did not directly affect the final price, but it is clear that commercially, Nvidia will be less comfortable AMD, if he wants to make money with this GPU, or at least not losing too much because the segment of ultra high-end graphics cards to play is primarily intended to promote the brand. Nvidia has also profitable course architecture on other segments with Quadro cards and cards Tesla.

Nvidia announced two versions of GF100. In addition to the GeForce GTX 480 and the GeForce GTX 470, which will be tested shortly, makes its appearance. It uses a GF100 neutered a little more, with 14 SMs and 16 functional memory bus reduced to 320 bits instead of 384 bits. AMD has a large advantage in terms of computing power, but based on the behavior of vector units, less effective. The Radeon HD 5800 also dominate at the fill rate, texturing etc. Note about fill rate that the GeForce GTX 480 and 470 are limited to the level of RIP to 32 pixels per cycle, despite the presence of 48 and 40 ROPs. Finally you will notice the relatively low frequency memories of GDDR5.

GTX 480

The GeForce GTX 480 uses slightly different design from what we saw in the past with Nvidia. Thus an opening in the hull causes the top of the radiator to the air. This upper part is closed, however, so that the hot air passing through it is properly ejected outside the system. The basic system allows for five heat pipes in direct contact with the GPU, rather to his heat spreader.The format of the PCB is identical to that of the GeForce GTX 285 and Radeon HD 5870 reference is 27cm. These however have a somewhat longer view of their hull protruding from the PCB. The card occupies two slots and of course takes a little extra space on its top for heat pipes that stick out. They do, however, no more space than the 8-pin power connectors and 6-pin required.

The card offers two dual-link DVI outputs and a mini HDMI output, which saves a little space to allow the full width of the grid to evacuate hot air. Note that only two of these outputs can be used simultaneously. Although clocked at 924 MHz only (1848 MHz for sending data), the GDDR5 memory, Samsung signed, here is certified to 1250 MHz. While Overclocking this card can earn 15-20% more performance and is very feasible using Afterburner.

The default clock speed for the GeForce GTX 480 is 700 MHz for the GPU , 1400 MHz shader and 3700 MHz memory. With additional tension, it is able to grow to 850 MHz GPU and 1700 MHz shader. The price for this result is not absurd, because the card goes up to 90 C °, the fan is 100% and power consumption to 300 watts.

Geforce GTX 470

Compared to the GeForce GTX 480, the design of the GeForce GTX 470 is more traditional and does not show the top of the radiator. However, it has also two small perforations in the PCB that allow the turbine to be supplied with air by the two sides of the card. Its PCB is also shorter with a length identical to that of the Radeon HD 4800 reference, or about 24.5 cm. It provides a connection similar to that of the GeForce GTX 480: two dual-link DVI outputs and an HDMI 1.3a. Two 6-pin power connectors are required.

The GeForce GTX 470 Super Overclock Edition is a reworked on several points of the GeForce GTX 470. We are entitled to an architecture of power twice as large as the reference model with 12-phase power supply for the GPU and the VRAM 2 and using high quality components (Ultra Durable + VGA). As for technical features, the GTX 470 aboard SOC 448 stream processors, 1280 MB of GDDR5 memory and a 320-bit bus. The operating frequency is 700 MHz for the GPU, 1400 MHz for the shaders and 837 MHz for memory. So we overclock the GPU and original shaders (607 MHz and 1215 MHz for GeForce GTX 470 Classic).

SLI

The SLI system is hot, very hot. At 110 ° C for the GPU hotter, it is even dangerous, yet this time, Nvidia significantly lower frequencies. When we first load test, we are to finish at 1,500 fps to 800 fps! Note that the system was, moreover, not stable. Clearly a case such as the Antec Sonata 3 is not suitable to receive two monsters too greedy. To use the GeForce GTX 480 in SLI will require a more spacious and take care of feeding them specifically with fresh air, or use the water-cooling. Such a system is to be reserved for advanced users. The texturing units of GF100 show here the same performance as the GT200, with the exception of textures that contain the data depth (D32F) whose access gains in performance. You will notice that the GeForce are not able to handle RGB9E5 textures at full speed, unlike the Radeon.

The GeForce GTX 480 and 470 are awesome and here the Radeon level of effectiveness against the rising level of ant aliasing. Despite its 48 ROPs, the GeForce GTX 480 is limited to 32 pixels per cycle or less. With a higher frequency, it is usually a bit strangely behind the GeForce GTX 285, 2 exceptions. The first is a surface with single-channel 32-bit where GF100 more effective. The second concerns the blending of 128 bits, very heavy in memory bandwidth, which is also more efficient.

Recommended Range - 700-775W

• XFX Black Edition 750W
• Seasonic X-750
• Thermaltake Toughpower XT 775W
• Enermax INFINITI 720W
• Corsair HX750W

XFX Black Edition 750W

After successfully flooded the market for graphics cards, the manufacturer XFX today tackles the wonderful world of power, and as many say he does not want to do it discreetly! Also amazing for its design as for its performance, the Black Edition is a powerful entrance into the big league. Tranchant radically with the simplicity of current power supplies, the Black Edition immediately attracts the eye. A huge fan overlooks the block, dressed in a green foil and enclosed behind a protective grid size spider. All power seems dressed in armor ultra-modern sharp lines, giving the whole look really unusual.

History of making everyone agrees from the outset, XFX has offered the services of Mr. Seasonic in person. The interior of the block is filled with high-quality components, heat sinks and equips even the mighty modern circuit DC-to-DC which is a top quality at 12V drained. The latter is sent on a single rail of 62A monstrous, a maximum total power of 744W just for the +12 V! What largely fueling the most demanding configurations. Listed connectors, XFX chose the modular hybrid: the main cables are fixed and you add the rest depending on your needs. You will find among other 4 PCI-E (6 +2) and 11 S-ATA connectors.

Seasonic X-750

In many power supplies circuit boards manufacturer Seasonic are installed. Under his own name but only a few power supplies are available. Now, however, Seasonic far and, with the X-750 to one of the first certified gold 80Plus power supplies. But not only the power of this certificate makes it interesting. It also wants a completely new layout. Now, the X-750 by now a successful Seasonic power supply? This response can be clearly yes answer. In addition to better efficiency with a peak of 92% of us could convince the stable voltage with increasing load. But the cooling principle, which has devised Seasonic is effective and mostly inaudible.

Only with an average load switches to the built-in fans and provides fresh air. By then the power supply is almost inaudible. However, drawing attention to our power supply a faint whimpering on the working electronics. Next to it is only in comparison low PFC (peak: 0.978) is a small drawback. Overall, to say that the X-750 power supply with a new and thoughtful layout. The use of SMD electronics a lot of space is saved. This step in the future could perhaps be made more compact and efficient power supplies. The X-750 before making any case that it works.

Thermaltake Toughpower XT 775W

The range of Thermaltake ToughPower our foam boxes for several years now, proving its reliability with each new version. The variation in this XT, the latest, pushing the yield up a nice block certification Bronze (82% efficiency) but also adds some advanced features that greatly lengthen the life of your equipment.

• FanDelayCool: A clever feature that allows the 140mm fan continue to run a few seconds after shutting down your PC, thereby cooling the components inside the unit and maintaining a stop too abrupt breakdown.
• SPT Indicator: the flank of Toughpower XT is equipped with three multicolored LEDs that tell you in real time the status of your diet. Temperature, good resistance +5 V and electrical failure are well monitored, allowing you to react quickly when problems arise.

Enermax INFINITI 720W

The new range of modular power supplies from Enermax. As a reminder, Enermax Technology is simply one of the leaders in the highly competitive power supply units and, increasingly, is the most closed circle of power supply manufacturers. A new modular block this brand needs to be reviewed so we will do this exercise in style in its 720W.

All 12V rails are individually protected against overload, as the corresponding test will tell. Also the power supply would turn off if the output would rise dangerously high or the input voltage is too low. Especially noteworthy nor No load operation: can the power supply is through bridging start even without a connected computer, it needed but during exercise a minimum load on at least one 12V rail, which is guaranteed by modern computers ever (supply the CPU with 12V). Consequently, only one 24-pin and not a 20-pin ATX power connector has been removed. The power supply corresponds to the latest ATX 2.2 specifications and is backward compatible to 2.0 but not more to the very old 1.3 specification.

The power supply has two additional special features: Power Guard 'is a monitoring function in the operating conditions. A tri-color LED and a built-in beeper can signal together five different operating conditions, such as the address of a protection circuit due to overload, over voltage or too low load or a malfunction of the power supply fan. CooGuard is something more than a normal follow-up control: After the shutdown of the system remain all voltages yet received for ten seconds to two minutes so that all the fans (not just the power adapter) continue to turn until the body temperature is cooled below 45 degrees Celsius.

Corsair HX750W

The Corsair HX750W 850W and are available in stores recently, and are highly acclaimed by the first buyers. That will certainly unleash more passion, because then that Corsair had relied on a certification 80Plus Silver for his two newcomers, the 80Plus Group has just delivered its verdict: it will be Gold at last! Remember that it takes to get this label to get at least 87% efficiency at 20% load, 90% to 50% load, and finally 87% to 100% load. The HX750W is finally obtained respectively 88.04%, 90.02% and 87.04%, thus securing gold for a hair, while HX850W is a bit more comfortable with 89.14%, 90.38% and 87.06% (very fair anyway 100% load).

It is therefore closer to the image you can dream of power, with the scalability, performance 80Plus However, a single +12 V rail and ultra powerful (62A and 70A on the HX750W HX850W), a security 7 years and finally: prices far from being unreasonable: 139 € on average for the 750W and 159 € for the 850W, prices should fall more quickly once the power available from a little all the signs of SVC so that the price war does its work. It remains now to rival brands the difficult task of showing us they can compete with Corsair.

Corsair Professional Series power supply units have been designed by Corsair and engineered to the highest quality standards to meet the demands of enthusiasts that expect the very best. The Corsair Professional Series HX750W PSU utilizes advanced DC-to-DC circuitry and meets 80 PLUS SILVER certification standards for up to 90% energy-efficiency, reducing wasted energy and lowering the amount of excess heat generated. Corsair Professional Series power supplies are built using industrial grade electrical components, ensuring the stable, clean and reliable voltages that are essential for high-end gaming PCs and workstations.

Last Words

The GeForce GTX 480 does not shine by its consumption at rest. It is therefore a greedier Radeon HD 5970 dual GPU. It's the same video playback. The Radeon HD 5870 is much better at this level. But Nvidia strongly lowers the frequencies of the card to rest which is 50 MHz for the GPU and 67.5 for the memory. The GeForce GTX 470 also sees his move to 50/67.5 MHz frequencies and is much more efficient, staying at the GeForce GTX 285 at rest and at the Radeon HD 5850 for video playback. The Radeon HD 5870 2GB shows a slight increase in consumption compared to the classic version, which brings it closer to a GeForce GTX 285 for example.

If consumption of the GeForce GTX 470 is more reasonable, it remains very high. Depending on load, it is below or above that of the GeForce GTX 285. The Radeon HD 5870 2GB consumes 30 watts more care than the 1GB version and displays a consumption similar to the GeForce GTX 470. The GeForce GTX 480 and noisier than the dual GPU cards and also the recent Radeon HD 4870 X2. The GeForce GTX 470 is fortunately more reasonable load, but remains very much noisier than the Radeon HD 5870 and 5850, with a similar level to that of the GeForce GTX 295.

AMD had done a great job in significantly reducing the temperature of its latest high-end GPU, the opposite side of Nvidia. It is no secret, the Watts are dissipated definitely there and even using a cooling system swifter, the temperature rises. If the GeForce GTX 470 display temperatures similar to that of the GeForce GTX 285, it is different from the GeForce GTX 480.
