Re: Do I need this much power?
I would not consider Ultra trusted still. In the past few years they had some bad models and they were off the list for while to most people. It was the same deal with Antec for Ultra. ...both are slowly starting to win some of their rep back with the enthusiasts for now. Coolermaster is also certainly not "trusted" by any means except for a few higher end models.
the most trusted are
However FSP, OCZ, Antec, Ultra, Xclio and a few more are all very good brands for the money.
The enermax you have said quite possibly could be the bad model that I had heard they made...I believe it was the Liberty..
