Looks like they're saying it will pull 363w under full load. Sounds very right to me.
363+363 is seven hundred... on the graphics cards alone.
Each pin on the PCIe x6 and x8 that is yellow will carry six amps. 18 amps per connector, 36 amps per card max draw. 430watts or so. This is the 400 watt cap that the industry banks on.
So, assuming you're gonna overclock and have more than one hard drive and maybe four sticks ram and push your CPU and have fans... you're looking at 1000 watts with at least 850 solid on the 12v rail(s) in order to meet/exceed the stock rated consumption.
To meet the absolute top rating you're looking at 400+400+200 of 12v sustained.
I will tell you once... NEVER SKIMP ON POWER SUPPLY. Having to tell you twice will cost you too much money.
They're not that much more expensive if you can afford two cards you can afford a huge supply.Edited by prjindigo - 4/7/11 at 5:07pm
