The COUGAR PowerX 550W PSU

As it befits COUGAR's focus on aesthetics, their PowerX 550W power supply was designed to look good. The PSU has a two-colour scheme - bright red all around, with the back and underside powder-coated matte black.The powder coat is a nice touch - imparting a nice look and texture, while making those surfaces fingerprint- and scratch-resistant.

One side of the PSU has a very nice embossed COUGAR logo on the outer side (when installed), and a label on the inner side. Of course, you can install it with the fan facing upwards. If so, the label will appear on the outer side instead, but don't worry - they made sure it will appear aligned correctly.
