Corsair, a worldwide leader in high-performance computer and flash memory products, today announced that it has been voted “Best Power Supply Manufacturer” by the readers of Custom PC Magazine for the second year running. Corsair was chosen above all other brands by Custom PC’s audience of true technology enthusiasts and overclockers in the magazine’s annual awards survey. Over 4000 votes were cast and Corsair emerged as the clear winner in the Power Supply category with high scores in all areas, including ratings of 9.5 out of 10 for Performance, Reliability and Build Quality.

Antec knocked the ball out of the park with the SG-850, and repeated the feat with the SG-650. I simply haven’t met a unit that can outperform these units, and my challenge from last time seems to have gone unanswered so far. There are only three ways I can think of to improve the Signature line: release a 1kW version, bring up efficiency enough to get gold or silver from 80 Plus, and drop the price just a hair more. Otherwise, the SG-650 is a wolf in sheep’s clothes – go buy one. You know you want to. Antec Signature 650W @ JonnyGuru

The OCZ ModXStream 600 is a lot of power supply in a relatively small package. Boasting 25A on each of its dual +12v rails, plus an additional 25A each for the +3.3v and +5v, the ModXStream 600 seems at least as capable if not more so than many power supplies with higher wattage ratings. It had no problems handling an overclocked quad-core processor and a single high-end video card under load. Although it touts being able to power both NVIDIA SLI and ATI CrossFire modes, with only a single 6-pin and one additional 6+2-pin PCIe cable, it is not going to handle two high-end cards, most of which require multiple power connections to work.

Marketing the UCP-700 as the Ultimate 700 Watt power supply is a bold claim.  I am happy to say the power supply was rock solid during testing with only a very slight change in voltage during stress testing.  These days I tent to favor modular power supplies but for many builds the extra cost is not a good tradeoff for a modular design.  The unique finish looks pretty sharp and gives the appearance of a coating more durable than the glossy paints so common in high end power supplies today.  Love it or hate it, it definitely stands out in a windowed install.  During testing the UCP-700 was slightly louder than our previous 1000W unit with exhaust temperatures stayed at around 95 Degrees F but never a distraction while working on the PC.

Not much more can be said that the meter couldn’t. It’s a strong PSU to say the least and can afford a bit more wattage over the top which I suspect was intentional on Antec’s part. The Antec Signature 850 Watt Power Supply is a stronger and more stable PSU than previous generations. The improved circuitry tightened up every feature of the PSU. Features like the voltage, power efficiency, and fluctuation levels where we most need them. Of course, we can attribute them to the Dual Layer PCB and Voltage Regulation Modules. Any time a bit of extra engineering can be applied to improve the performance of a PSU, it’s a great benefit and welcomed improvement. This is an Antec attribute. About the only thing that could use a touch up or two would be the PSU chassis. Another model with a polished paint job and/or LED or two that keeps in line with the Gamer series enclosures.
