I was wondering if the Corsair AX 850 would be enough to power 2 EVGA GTX 680 4gb cards. I know that PSU puts out up to 70A rail. So will 850 watts be enough??
One GTX680 pulls 195 W @ stock according to official specs, and since Nvidia are very
restrictive when it comes to overvolting their current cards, I doubt you can go much
higher than that.
So yes, the AX850 has plenty of power for 2 x 680.
