3x GTX 570's

post #1 of 8
Thread Starter 
What kind of wattage am I looking for in a PSU?

I'm building a 2600k rig and will eventually have three 570's in it. 2x 4GB DDR3 1600.

I might also have a dual pump watercooling setup, still thinking about it, but it might run off a much smaller and weaker auxiliary psu.

The 2600k will be oc'd quite a bit; the 570's as well.

I have a 1000w Kingwin Lazer that I have been pretty happy with thus far...I don't think it will be enough though.

So, will 1000 be enough, or should I jump up to 1200? Or maybe even more?

A good 850-900w unit would be more than enough. Your 1000w is overkill. So you're good to go already.

And no need for a second PSU, the one you have already is more than enough for whatever you want to throw at it, including tri SLI 580's.

You'd be able to run triple 570s on 900w. Dual 580s run on a 750, so triple 570s shouldn't be too far up on the positive side. 1000w would be plenty, keep your current PSU. Also, check this for a calculator, would give a better estimate.

I've learned through the years that overkill is better than too close to max when it comes to your PSU. You will be working your current PSU 70-80% at full load which is perfect IMO.
