780 TI SLI could be run from an AX 750 with overclocked gear. 770's will be fine.

Yeah but I'd refrain from touching any voltages. And MAYBE lower the gpu boost power target a little.

A 750 watt 80+ Platinum PSU is more than enough even when going balls to the wall on the OC.

...wait

 

do you actually have a Xeon running at 5.2 and near 1.6vcore?

 

It will run it fine regardless, 770 have been seen to approach 250W with GPU boost under grueling work loads, doing something intensive your PSU might run a bit warm and the fan might ramp up, but it's perfectly capable.

Oops got it confused for a sec with the AX 760 which is Platinum but still two 770s can only pull a max of 460 watts which is plenty left over.
