This PSU has some color compared to most manufacturers on the market, they have colored the case orange and black which are the main colors of Cougar. On the top you got the sticker that tells you the rail amps, and in this case we can see that it has four 12V rails.
Instead of a simple cheap looking plastic switch like most manufacturers use Cougar have placed a nicer and higher quality switch in the back of their PSU. The bottom is equipped with a ventilation grill below the fan.
This is a modular PSU so you can hook up whatever cables your rig requires, the cables are nicely sleeved to keep the case nice and clean looking. The black and red connectors on the PSU makes it easy to hook up the right cables, the red ones use the 12V rails 3 and 4 while the black ones use the rest. In case a rail is not enough it will take power from a unusued rail to keep stability and performance.
