Hey guys. I just got a new PSU, a Coolermaster Real Power 450W. Right now I'm on AGP, but eventually when I build a new rig with PCI-E, I will want to SLi. If possible I would like to "recycle" as many parts as possible, PSU included. Would my PSU, which has dual 12V ramps with 18A on EACH, be enough for SLi?
