Upgrade help

You obviously need a quality ps in order to power just the video card much less the rest of the system. Also you need to plug the 6 pin sli power connector into the video card. You should be looking for an atx 2.x compliant ps with at least 450w with at least 30+ amps on the 12v rail. I would recommend enermax but any "quality" ps will do the job.

a 350watt psu would be about the lowest he can go. if its a true 350...

Good brands are Antec, Enermax, Fortron, Tagan, XClio...

1. Make sure it's ATX12V 2.01, so it has dual 12V rails, SATA connectors, PCIe 6-pin connector, 24-pin or 20+4-pin main connector...
2. The combined Amps on the 12V rails should be more than 26A (preferably 30+A)...
3. Don't shoot for anything lower than 350W, 400W or more is advisable...
4. If possible, look for a PSU that sports PFC, it will be more efficient with the power it gets and needs...

BTW Have fun gaming...
