Hey, over the summer I tried to oc my cpu and it seemed to go strong. I had it oc'd to 2.2 from the 2.0 stock speed. I just had the stock cooling on it but it didn't seem to get more than a couple degrees hotter. it ran Prime95 without a hitch overnight and seemed to be running stable as a rock. But after a couple days I started getting voltage warnings when I would boot my system. I returned my system back to stock speeds and haven't messed with them since. I would however, like to try to oc again. I think it might be a psu problem that I faced before... can anyone shed some light on this? currently I just have the psu that came with my case (Aspire 500w) here are the specs: AC INPUT 115V/230V - 60/50Hz DC OUTPUT +3.3V +5V +12V -12V -5V +5VSB 500W Max Combined Watts 28A 30A 34A 0.3A 0.8A 2.0A 500W If I need a new psu what would anyone recommend? I was wondering if oxz was any good... maybe the OCZ520ADJ? I was also looking at the Enermax EG701AX-VEW or possibly the Silverstone ST65ZF... but this one is a little more pricey. Before I spend all this money on a new psu can anyone shed light on if I really need one? My specs are below. I was also thinking about getting a better cpu cooler.... would like to go w/ water but I can prob only afford the tt big water se... any advice?
