I would be somewhat concerned as the card uses up to 420W according to this http://www.tomshardware.c...gtx-980-ti,4164-7.html

But I would be skeptical of that and would advise you to just try it out because assuming that that number is wrong, then you would only use about 85-90% of your PSU's power rating which is fairly high as its reccomended to only use 80%. So using 90% could cause the PSU to fail within 6-24months at which point you can replace it.

Get the evga platinum plus 1k watt psu.

You could power that system with a solid 650w PSU. The GTX 980Ti doesn't use up that much power.

The 850w is almost enough for tri SLI GTX 980Ti's.

um that is for the cards only in that chart. you would be a damn fool trying to run 980 TI sli with a 650 watt psu. two oced 980 Ti cards alone can pull over 550 watts. throw in an oced cpu and the rest of components and even a 750 watt psu would get close to tapped out.

That 420w, is how much is needed not how much it uses. for instance I work with equipment that requires 30Kw, however the systems actual usage is only about 21Kw.

You can talk about theory's all day. If you want to recommend people get a 1600w PSU to be ready for overclocking and having 20 hard drives, go ahead. But it's ridiculous, that reviewer uses a i7 5960X which uses 1.375v-1.425v to get his operating speed. That's twice the amount of power of a i7 4770K. He could easily get away with a gold/platinum certified 650w PSU on a GTX 980Ti set-up.

perhaps you should learn how to read a little closer. the cpu used in that review is irrelevant and had nothing to do with what I said. that chart is only showing power consumption for the cards.
 
its a FACT that an oced 980 ti can use 275 watts so its simple math to say 550 watts is very possible for two of them if under full load. an oced 4770k can easily use 100 watts or more. that is potentially 650 REAL watts or more right there for oced 980 ti SLI and oced 4770k and I did not even factor in the rest of the components. so NO, a 650 watt psu is NOT enough for an oced 980 ti SLI system.

If it helps I ran 780 sli with oc 3770k with 2 externals and 4 internals along with all other normal accessories without issue for theast two years.

Only reason I updated psu was because I'm now running a 5930k oc which can draw about 400 watts on its own.

Lol! You don't know much about ssd life span do ya? Btw my build is for games. Nothing that matters. I do real work on my iMac/MacBook Pro.

Thanks for your concern.

O and also my wattage was monitored by corsair link. Never went over the 500 or so mark on previous setup I mentioned.

Talking about reading a little closer. I never said anything about overclocking in my original post. Yeah... 650w is enough unless you want to overclock.

nice try but you are the one that quoted and replied to me when I have said overclocking right from the beginning. and even at stock speeds a 650 watt PSU is going to be pushed to over 90-95% at times. in fact is someone was silly enough to do a full system bench it would easily exceed 650 watts.  

Hmm... post #8 is my OP that you quoted. You took my post out of context, started speaking about overclocking and saying I needed to learn how to read. I mentioned your theorizing as a point of taking my post out of context.
