No computer, workstation or server can work without a smartly chosen PSU. This humble component is more important than you think. Aside from powering the PC, it also affects the service life of other components and the overall power consumption. The 550W COUGAR GX-F550 ensures protected transfer of power from the mains to singular circuits, which subsequently power the used parts. The ATX PSU with a 550 W performance is designed for decently powerful gaming and professional mid-range computers. The Cougar PSU is equipped with a 135mm fan, which minimalises the temperature and positively affects its service life. You can cut the power supply using a power switch. Every PC PSU on the market has a label that tells you how effective it is at using the power from the mains. The 80 PLUS Gold tag means its effectiveness reaches 91 %. Removable cables ensure they don't get tangled into one huge mess.
