I have a HX1000, that has 2 rails of 500W.
One of the rails is used for the system itself, cpu, mobo, hd's, fans... the cpu is a i7 920 clocked to 4.5Ghz.
I'm thinking about using the 2 rail of 500W for both 6970's. Do you think it will be enough?
HX1000 power is known as being under-spec'ed. Some sources say this is a 1500W PSU but spec'ed at 1000W for 80 plus requirements.
Although i don't know if the 500W would be enough for powering 2 6970's ... what do you think? ( btw... would be great to know if you think that this amount of power would be enough for OC too ) ...
I failed to find a review where they show gpu power consumption, only, instead of the full system consumption.
x2 HD6970 -> 400W with furmark or FOlding
However, I can tell you, that while playing BFBC2 without vsync on my system, I never see any wattage above 400W including ALL my rig.
I think you'll be fine as long as you don't play Furmark all day long
