PSU for this system

post #1 of 8
Thread Starter 
New system. Here are the specs:

CPU - i7 2600k

GPU - (2x) MSI GTX580 OC

MB - ASUS Maximus IV Extreme

RAM - 4x 4GB G.Skill RipjawX

HDDs - 1x OCZ Vertex3 + 1x WD VelociRaptor


+ Watercooling pump


I'm going for either the Corsair AX1200, AX850 or AX750. I need room for some serious overclocking and maybe to add a 3rd GTX580 in the future.


Thanks a lot
Normandy

Corsair AX850... AX1200 if you're really going to add another 580

XFX 750w or 850 PSU will handle that with an extra 580 + OCing. Corsair is overpriced SOOO MUHC (like intel)

850W is fine for two GTX 580 overclocked with a i7-2600k, but you want more than that for a third.

For three GTX 580 with reasonable overclocks, a great value would be the OCZ ZX1000:

If you're really going to push three GTX 580 to the limit, try the 1250W variant:
http://www.newegg.com/Product/Produc...82E16817341046

They're going for $190 and $240 respectively, each before 10% instant promo off and $30 MIR. The AX1200 is better for sure, but these are plenty good already.

I think 850W is only fine with dual 480's? I would look into a 950 Unit.

A good 850W such as the aforementioned AX850 would be perfect here.

Well if you want to add a 3rd GTX 580 then just get an AX1200. Your spending this much already why not go the little extra and make sure.

GTX580s pull less than GTX480s, and SLI 580s can be run on a 750W.
