650 watt by seasonic

Depends on your budget but a seasonic x850 should work nicely http://www.newegg.com/Product/Product.aspx?Item=N82E16817151102

850w is WAY overkill on that system

 

[bignastyid]

A good 550w would work fine. 750w- 850w if you want to sli.

his motherboard doesnt support sli

As BigNastyID suggested, a good 550W PSU (e.g. Seasonic, Rosewill Capstone) would be sufficient.
