PSU for Crossfire 6970

post #1 of 16
Thread Starter 
What would be a good PSU for a crossfire 6970 setup? I will also have a 2500k, overclocked to maybe around 4.5GHz, and I plan on overclocking the two gfx cards as well. I was going to go with this
http://www.newegg.com/Product/Product.aspx?Item=N82E16817171056

But is it overkill? What are you guys' thoughts? (Look at sig rig to see parts that will be in this new rig I am building)

1000 watts for that rig is way more then needed. A good quality 750w would get the job done just fine.

way too much, get yourself an ax or hx 750-850 corsair and you will be loving life, unless you plan to go tri-fire.

I'm running crossfire 6970's on my SeaSonic 750w just fine.. I even tested my friends GTX480's SLI w/ furmark & it ran just fine.. SeaSonic is the way to go!

(I probably shouldn't be stress testing my PSU, but.. I was kinda curious if it could handle 2 480's @ full load tongue.gif)

A good 750W PSU will be more than enough for your rig.
