several psu manufacturers make a decent psu.however only a few really hold up well to critics.but even stil, some top name brands have had their run of bad luck with psu.antec for example has had a rash of bad psu just recently.this in no way means that antec psu are no good,it just means that even the big names have their problems sometimes.i currently have an ace 520watt psu and as you see by my machine specs at the bottom,i in no way am having any difficulty with it.so i guess the best thing to do really,is talk to some one you trust and go with their recommendation.
