Tags: Power Supplies Gtx Graphics Cards SLI Components Last response: June 17, 2012 9:13 PM in Components Share EmmetCBS June 17, 2012 7:57:20 PM I'm building my PC over the summer, and I'm getting a GTX 670 windforce video card. I also want to get another one next year, for sli, so i was wondering if a Cosair GS800w would run 2 gtx 670 windforce cards and an over clocked i5 3570k?
