PSU requirement

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.
 
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.
