Cougar aren’t exactly the first brand name you think of when we mention power supplies. Cougar have made a name for themselves with some uniquely styled cases and fans at affordable price points but their involvement in the power supply market is certainly something relatively new. Cougar’s Power X 550W power supply that we have with us today is one of these brand new power supplies from Cougar. Like a lot of companies selling power supplies Cougar are not actively involved in producing these power supplies as they are produced by HEC/Compucase. That said Cougar are one of the few brands that I know of who actually bring HEC/Compucase OEM power supplies to market (most use Seasonic, FSP, etc) so I am very interested to have a look at this power supply, so without any further ado let us do exactly that!
