Under full stress in a stress testing program, a top end Intel processor (130W TDP) & 2x 270X (355W) system would use something like 500-550W's. So you'd be pushing 100W or more due to your CPU, 600-650W.

Of course under normal gaming situations this will be lower, and 750W will be fine. if you plan on overclocking though, you may be okay, but Perhaps consider upgrading the PSU for peace of mind (850W-1000W).
