I power 16 overclocked Ant S3's with 8 EVGA SuperNova G1's. They are gold rated, modular, come with enough cables to power all 8 ports on two S3's, and come with their own plug that snaps on to the motherboard cable so you don't have to shove paperclips in the holes to run it without a motherboard. One of the best you can buy IMO. Had them running for 5 or 6 months straight now with not one issue.
