is 550w enough?

[Spectator]

Considering upgrading my gpu to a 980ti , I already have an i7 4790k. Pc part picker is estimating 486 watts power draw. My questions in would a 550w evga g2 be enough? 

[WoodenMarker]

Yes, it would be plenty.

i recommend 650 just because 980 ti, if you want some headroom, but it should be okay

A PSU is an important part. I wouldn't skimp on it. And you're pushing it, if you ever want to upgrade, you'll have to buy a whole new psu. So an extra $50 tops now, or another $100+ later.

Your choice.

But a PSU is a pretty 'future proof' piece of hardware if you get extra wattage you don't need. Hence my 750w for 4690k and 750ti I have.

Are you overclocking either the 980ti or the 4790k?

 

I'd go a bit bigger.

Very good points about over clocking. I will definitely go for the 650 watt. or even the 750 watt.

Huh? For a single 980Ti, a 550G2 will easily handle your system, even with overclocking.

well yes you are right but it will be pushing 550 watts, leaves no room for upgrades

It would only push 550w with extreme oc'ing and a similarly power hungry cpu. 

I don't see a single gpu pulling more power than a 980 Ti any time soon. 

If you plan to add another card for sli, that would be a good reason to get a bigger psu. Otherwise, 550w is already more than enough for any single gpu.
