Totally depends on the rest of your components.

Best way to figure out: Put your PC under full load, get a device between your PC and your power plug to measure the watts. Look at wikipedia how much the 980ti will need and do the math.



I use a 3 gpus. And my system (3770k, 1ssd, nothing else) rarely goes beyong 800 watts when maxing out everything.

Also a good tool for doing the calculation is this one:

I've found it useful

it should work OK I'm using 980ti, 590gtx, and 580gtx .. on 950W PSU .. no probs there 590 uses more power than 980ti

Keep in mind that if you plan to use the 780 for octane in conjunction with the 980 ti you are limited to the 780's 3 gig ram, unless you have the 6 gb version.

Finally yanked my two old ghetto water-cooled 580 3GBs and slapped a couple EVGA 980Ti Hybrids in... Wow! Just did some test renders at full blast and neither one ever got above 49°! Might have to pull the 780Ti and get another or two of these bad-boys. Practically dead silent too.. even with the stock fans. I could have put my Corsair SP120 Quiets on the rads, but see no need, yet.

And FYI guys, the new EVGA Hybrids apparently now all ship with the kick-ass silver shroud -- like their face off program version -- where you could get this sweet shroud shipped to you for replacement. These pups are sexy! I was totally expecting those fugly shrouds, as shown in Amazon images... what a wonderful surprise! Not that I have a side window, or look inside workstation much, but still real nice.

Gonna go fire up a game and test further!
