I've got an HX750, but I'm a little worried that it won't be enough to power the two.They are Sapphire Tri-Xs and the one I have is OCed to 1100/1400 with a VDDC offset of 80.

The HX is a great power supply and should be fine. I'd reset the first to stock settings just so they're running at equal speed.

You should be fine with that 750. If you still don't feel comfortable, you can invest in an 850W power supply and that should be more than enough.

That only used 550W for both GPUs. 750 should provide plenty of leeway.
