Overclocking PSU requirement

I need help knowing if my Rosewill 750W 80 plus gold will be enough power to overclock both gtx780 ti Superclocked and the new i7 4790k that is coming out. Also, does it mean they are overclocking the hardware when they say, "full load"? Here are some sites I found with wattage use:

and

I would say no.

The 12 volt rail on your psu is 62 amps.

One evga gtx780 ti requires 42 amps on the 12 volt rail.

Full load means the gpu is at maximum usage without overclock.

Hello, nice to meet you!
I would say yes easily, because I think you're saying that you have one (1) GTX 780Ti plus your CPU.
But even SLI will be okay if you don't overvolt.

+1 to what hellokitty posted above.

Single gpu is fine. Sli may be just enough.

Misread sorry.

Just to clarify for the OP, his 750W PSU will be enough for his setup. You will not need to upgrade to the 1000w PSU.
