Irrelevant unless you run your rig at an efficiency sweetspot 24/7.

A quality 750W power supply is still quite enough for that.

I already got the 850 lol. Guess it's better to be safe now than to feel sorry later.

Two HD 6950's and my i7 950 @ 4.2Ghz pulled 881W while furmarking + priming, so if you'll fold the 850, otherwise 750 is fine.

You would have had more power than you needed with the AX750.

Guru3D was able to get their test system to pull 578W from the wall outlet when it had two GTX 570s in SLI under full load. That means that the system pulled about 490W from the power supply. Guru3D also recommends adding about 100-150W to account for the rest of the system in order to get more of a total system power draw at full load, so that comes to about 640W. So even a top quality 650W power supply would be enough.

At least you didn't get a low quality PSU.
