i7 930 Intel Processors
ProWater 850i Liquid Cooling System

A pair of 5850's needs about 20 amps (well, 18 amps to 24 amps peak). The CPU needs about 10 amps. Overclocking will add up to 20% to that figure.

A good 650 watt PSU will work, but I think it would be kind of close. A good (Seasonic, Corsair, Antec, or XFX) 750 watt PSU would be better.

since you're going to get 5850's, go with this combo & save $35.00, also, it's an 850-watt Corsair PSU so you have a lot more room for future upgrades.
