Power supplies have really advanced in the last 2 years. Some of the advancement is from innovation, the other is from the necessity for more strict power guidelines. With power hungry processors and video cards on the market, older PSUs are becoming obsolete because they can not handle the load todays PC parts require. With this in mind, we are going to retire a Thermaltake 360W Purepower PSU and replace it with a new Thermaltake 520W Purepower Power Station that is ATX 12V 2.0 compliant. This upgrade should show most of the reasons one would want to upgrade their PSU.
