<p><span style="font-size: small;">Although many users are currently looking for smaller power supplies below 500W, there still is a demand for stronger ones, particularly if you are a gamer with Triple-SLI or Quad-Crossfire systems. Those planning on running NVIDIA's next generation &quot;Fermi&quot; will want a fairly beefy PSU, and the same goes for Folding@Home farms where you'd want a lot of stable power. For the upper end PSUs there are a wide range of models, which doesn&rsquo;t make the purchase decision easy. In addition, these power supplies are usually expensive so you'll want to get the best features and a reliable power supply that can operate even under maximum load and summer temperatures.</span></p> <p><span style="font-size: small;"> We received a TruePower Quattro 1200W from Antec and as usually we're looking to see if it provides a good overall package. We'll check out the safety features, voltage stability, and the available connectors. Efficiency is also an important issue and affects the energy consumption as well as the internal temperature. We also got a special OC version from Antec. It has two big regulators for the internal fan and +12V voltages. You can easily adjust the rail when the voltage drops down too much. In all other areas the OC version has the same features as the standard model.</span></p> <p><span style="font-size: small;"> The TruePower Quattro 1200W is a PSU that polarizes because of its 80mm fan. Usually a bigger fan also has a bigger cooling area, but lot of it depends on the fan-quality and cooling topology. With a 120-140mm fan mounted on the bottom, you have a curve in the airflow, but with 80mm the airflow is more direct. So temperatures should not be a problem. But will the fan be silent enough for most discerning buyers? </span></p> <p><span style="font-size: small;"><a target="_blank" href="http://www.anandtech.com/show/3807/antec-truepower-quattro-1200w">Read more...</a><br /> </span></p>

Round one of the high-priced enthusiast end of X58 went to EVGA last year, who set the pace with their Classified line of motherboards. While not perfect in every regard, the E759 and E760 broke and set more overclocking records than any other product, elevating the Classified series to must have status in the eyes of overclocking and gaming enthusiasts.

In light of this success, it was clear that ASUS, Gigabyte and MSI would have to go back to the drawing board and come up with new designs to captivate the audience. The launch of Intel’s i7-980X Gulftown together with the availability of SATA 6G and USB 3 controllers from Marvell and NEC provided the excuse for a revamp and here we are a couple of months down the road with everyone vying to capitalize on sales thanks to the longevity of the X58 platform. That’s where we pick up today, we’ve got the very best ASUS, Gigabyte, EVGA and MSI have to offer and have lined up a compare taking a look at basic functionality, overclocking and overall stability.

Today is what OCZ calls the ‘unveiling’ of their new 4GB DDR3-2133 MHz memory modules, running at 1.65V.  Along with the unveiling, OCZ are extending the modules into 8GB dual channel kits and 12GB triple channel kits, up to 2133 MHz.  The Platinum Series will aim to cater gamers and high density users, whereas overclockers and enthusiasts may plump for the faster and more expensive Flex EX and Reaper HPC kits.

In 2007 we reviewed NVIDIA’s GeForce 8800 GT. At the time we didn’t know it would be the last NVIDIA GPU we would outright recommend at launch. Roughly two and a half years have elapsed since then and in that time AMD went from competitive to dominant in the marketplace. The RV670, RV770 and RV870 trilogy were all very well executed. The latter two came at a time when NVIDIA’s pricing and execution strategies took a major tumble.

Given how well AMD has executed since 2007, no one expected anything competitive from NVIDIA throughout the entire Fermi/GF100 family. Cutting down a very large, power hungry architecture wouldn’t magically produce efficient GPUs. Had NVIDIA done that, the tone of today’s GeForce GTX 460 review would’ve been very different.

Instead, NVIDIA did the unexpected. It delivered a GF100 targeted at serving the needs of the high end gamer and GPU compute user, and a reworked GF104 aimed at being a pure gaming chip for the performance mainstream segment. By pulling out ECC support entirely and significantly dropping FP64 compute power, NVIDIA freed up enough die area to add more issue and math hardware to the GF104’s SMs. The end result is a $200 - $230 part that’s better than anything else at those prices on the market today.

Yields and manufacturability, while still not great at 40nm are much better than when GF100 first launched. That combined with NVIDIA disabling some hardware on the first incarnation of the GF104 makes the GeForce GTX 460’s birth a good ol’ hard launch (at least for the 768MB version). Newegg had cards for sale several hours before the midnight NDA lift, and we had no less than 6 cards in house before our review went live.

We have two reference cards from NVIDIA (a 768MB and 1GB version), two 768MB cards from EVGA for SLI testing, a card from Zotac, and finally a card from ASUS. The EVGA GeForce GTX 460 SuperClocked is a reference design but factory overclocked. Zotac’s GeForce GTX 460 ships at stock frequencies but comes with a custom cooler. And finally ASUS’ ENGTX460 TOP 768MB is an entirely custom design running at a slight overclock with voltage controls and custom cooling.

NVIDIA is emphasizing overclocking potential of the GTX 460, which is why we see so many different versions of the card on day one of availability. The focus on factory overclocked cards, custom cooling and custom PCBs is not a coincidence. In our testing we found a least 20% headroom left on the GTX 460s we received.

<p><span style="font-size: small;"> At the very end of May we saw NVIDIA&rsquo;s first effort to expand Fermi beyond the $300 space with the </span><span style="font-size: small;">GeForce GTX 465</span><span style="font-size: small;">, a further cut-down </span><span style="font-size: small;">GF100</span><span style="font-size: small;"> core priced at launch at $279. Unfortunately for NVIDIA, it wasn&rsquo;t even a lackluster launch &ndash; while GF100 performs quite well with most of its functional units enabled (i.e. GTX 480), disabling additional units isn&rsquo;t doing the GPU any favors. Furthermore disabling those units does little to temper the chip&rsquo;s high power draw &ndash; something that&rsquo;s only reasonable on the higher-end cards &ndash; resulting in a card that ate a lot of power while losing to AMD&rsquo;s Radeon HD 5850.</span></p> <p><span style="font-size: small;"> In short, the GTX 465 is a lesson of how you can only cut down GPU so far. NVIDIA went too far, and ended up with a part that had GTX 285 performance and GTX 470 power consumption.</span></p> <p><span style="font-size: small;"> Today NVIDIA is back in the saddle with something entirely new: GF104 and the GTX 460. The second member of the Fermi family is ready for its day in the sun, and in many ways it&rsquo;s nothing like we expected. Designed from the start as a smaller chip than GF100, GF104 is the basis of the GTX 460 line of products which fix the GTX 465&rsquo;s ills while delivering the GTX 465&rsquo;s performance. It&rsquo;s what the GTX 465 should have been, and it&rsquo;s priced as low as $199. And as we&rsquo;ll see, it&rsquo;s the first NVIDIA card in a long time that we can give a glowing review for.</span></p> <p><span style="font-size: small;"><a target="_blank" href="http://www.anandtech.com/show/3809/nvidias-geforce-gtx-460-the-200-king">Read more...</a><br /> </span></p>
