Well I'm going to try to overclock my s3 with just one 500w evga 80 plus.. Hopefully it works out!
Should be ok, quote from the EVGA page -
"Supporting 40A on a single +12V rail"
As far as I understand the S3's use about 28-30A at stock, so there's some headroom. I'd start at 225 and check the cables to see if they're getting toasty
Rinse and repeat
