About a year ago I was looking for a new power supply for my new PC, which is quiet, offers sufficient power and lasts a long time. All this has fulfilled it. It's pretty much the quietest component in the whole computer. In addition, the performance of my computer ranges (AMD Radeon HD 6950, i5 2500K @ 4.2 GHz) from perfect. And so far it works still as good as the first day. (If this changes once, I'll resent here). LG
