Everyone is quick to shit on Rosewill, but I doubt many have even used them lately.
I have a 450w that ran a 9600GSO and E2200, which was later upped to a E5200 that ran 24/7 Folding and Crunching no issues. Its still going to this day and before I had it Mike047 had it crunching 24/7 in his farm of 939 X2s.
The 600w model I have now runs my Phenom 965 9600GSO folding and crunching 24/7 as well, no issues. Used to power my main rig in specs (WCG0) 24/7 as well, and before that Mike had it in his farm too.
These newer ones are built very well and if they are surviving Folding and Crunching 24/7 (and numerous power outages too) they will surely survive any round of Crisis, CS:S, or whatever game everyone is playing now.
