I bought this power supply in sept 2011, it's a gold rated 850 that just doesn't quit. it's quiet, even under load, it's very efficient, gives good clean power. if you are lucky enough to pick one of these up, go for it, i got mine for 130, with a 50$ MIR, making it 80 bucks, just a steal. It's been in my rig on 24/7 since september, never given me any semblance of an issue. A+ on this guy.
