What PSU for 6990?

[cesium666]

Thinking about going from my 5850 to a 6990. Rig is in sig, but will recap below:

Intel Core i7 920 @ 3.8GHz
Gigabyte GA-EX58-UD4P
6GB Corsair PC3-12800
640GB+2x1TB+2x2TB HDDs
120GB G.Skill SSD
XFX 5850 @ 975/1200
Four 120mm fans

Right now I have a corsair HX620. I'm assuming that it won't be enough to run the 6990, so I'm looking for the next logical step up.

I'd much rather not dish out for a 1000W PSU, so would something like the HX750W work fine? At $130 it doesn't break the bank, and the 80% Silver cert is always nice.

HX750 is fine for your system with the 6990 overclocked to its limits. I would look at the XFX power supplies, as they tend to be cheaper than the Corsair HX series while being as good.

If you don't intend to overclock too much, the HX620 should handle it fine. If you do want to overclock, the HX750 would be a good choice. The XFX equivalent is this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817207016
