PSU for GTX 580 SLI

post #1 of 3
Thread Starter 
Would a 850W PSU like this:

http://www.newegg.com/Product/Produc...82E16817207001

Be sufficient, or should I go with a 1,000W PSU like this:

http://www.newegg.com/Product/Produc...82E16817256057

(This would be with an overclocked 2500K)

PS: Are open box deals / used ebay purchases a bad idea generally?

The XFX 850W is more than enough - and it's a great power supply too.

If you can find a cheap used part and the warranty can be transferred - I don't see why not. As long as it's in good shape you should have no problems with it.

That XFX 850w would be an excellent choice.
