Is my PSU enough for GTX 980 SLI?

[Qgon]

Hello!

My System:

i7-4790k (4,4GHz)
16GB RAM 1600 MHz
250GB SSD Samsung EVO
GPU: 2x MSI GTX 980 Gaming 4GB SLI (OC 10%)
PSU: Thermaltake 630W Berlin 80+

My Question is. Is this PSU enough for my Setup or should i go for a better PSU?

Thanks for your help

You want at least a 850W psu for GTX 980 SLI.

A top tier 630w should be enough, but 850 would be nice for long term.

980 = 165w x2 = 330w
System ~= 250w
Total 580w
Ideally run at 80% max of PSU = 725w
Also nice to have some headroom for an OC.

Thanks for the answers. I will go for a little higher PSU i guess.

I think i will go for a 1000W or 1050W PSU since i don't want to upgrade it in 2 years again. Which one would you prefer?

I thought about:

what do you think?

Not sure if those are any good TBO.
Somewhere on Toms is a PSU Tier list.

Currently, I like Seasonic and their hybrid fan. It doesn't spin below a certain temp, keeps things quiet.
1000w is plenty overkill. The current trend for chips is power reduction, so the days of 1000w PSU's are limited.

Expensive, but something like this is all you'll ever need for an SLI setup, unless you're going 980Ti SLI level... or AMD.
