One of the worse questions any builder can ask is: "How small a PSU can I use". Personally, I never load a PSU past 50%.

That high quality PSU would even handle a rig with two 780Ti in SLI.

 

[STACKS ON DECK]

this PSU is perfect . . why too much confused . . this psu can handle a little more then that

 

[earruiz]

Ram1009 I think you're mistaken I wasn't asking for a minimum I was asking if my current was enough if it wasn't or if you recommend higher than I would like to hear suggestions and product recommendations

The AX 760 is enough for the 780 ti and probably for 780 ti SLI. You should have no problems with the upgrade power supply wise.

Your Current PSU is a fine choice for Single, For SLI probably a 850 would be a better choice..
