If I have a PSI that is powerfull enough to run SLI, but it desnt have the extra PCI-E conector, is there anyway I can run SLI without buying a new PSU? Can I add another cable if its mudular?
do you mean the power connector for your video card? if so, then no, i wouldnt risk damaging the card or mobo. Why would u possible need 2x 7800gtx's anyway?
