I'm having a problem finding a lower wattage (300-400) psu that still has active PFC, dual 12v rails (if not 3 or 4), and is SLI supportive. Although my build is on a budget now, I want to have opportunity to expand later. If I want to SLI two GPUs, won't I need to find an SLI supportive PSU?
Also, is having a psu that is modular worth it? I read on a site I can't remember where now, that modular creates greater resistance which reduces power supplied and can cause a system to be more unstable. Is there any truth to this?
