Without any fanfare or ballyhooing, XFX this week expanded its power supply lineup with its new Pro Series with "EasyRail Technology." What exactly is EasyRail Technology, you ask?
From what we gather, it's XFX's fancy way of saying the Pro Series utilizes a single, beefy +12V rail rather than spreading the available amperage out across multiple +12V rails.
The Pro Series is available in 650W, 750W, and 850W models, each of which is 80 PLUS Bronze certified, which means they run at 85 percent efficiency with a 50 percent load. They also look to be CrossFire and SLI certified with support for up to 3-way multi-GPU configurations, depending on the videocard, and sport fixed cables.
We've only spotted these in the UK for around $106 (650W), $115 (750W) and $130 (850W). No word on when these will ship Stateside.

Yes it's true that most of them test at like 25 degrees but seems XFX claim that they will support 80% efficiency even up to 50 degrees with their true wattage guarantee. Check out these reviews that said in their tested they pushed it past 50 and still got above 80% efficiency.

80 plus certification is done at a room temperature of a refrigerator, that is absolutely ridiculous, why is nobody complaining about that? my case gets about 40 degrees or more, not 25 like they use to test the power supplies.
Ecos consulting co. ( the company behind 80 plus certification ) is nothing but a scam the way I see it.
