Today we take a look at the Cougar PowerX 550W power supply. Never heard of Cougar? well they are a retail subset of parent company HEC. The PowerX 550W is a 80 Plus Bronze certified, compact, non modular design built into a brightly coloured chassis. We last looked at their CS 800W unit in January this year and while it didn’t earn a really high award from us, it was a capable all round unit.
