Cougar`s new PowerX 550 Watt PSU uses an edgy black and metallic orange exterior treatment to make an immediate sensory impact. The Cougar PowerX 550 Watt PSU obviously brings more to the table than good looks, with an 80+ Bronze certification, dual 12V rails and some of the most advanced protection circuitry we have seen to date. In addition to the more typical protections included (OCP, SCP, OVP, UVP, OPP, OTP), the PowerX 550W adds OVP to the 5VSB to protect any devices plugged into the USB. To insure clean accurate power, the Cougar PowerX uses top quality Japanese capacitors, as well as an Active PFC circuit with PF up to 99% to make sure your equipment is getting the clean power it needs. The PowerX 550W is rated for continuous operation at 40 degrees Celsius, and an active 120mm fan keeps the PSU cool with a minimum of noise. The PowerX 550W conforms to all of the latest ATX specifications, and is ErP Lot6 2013 ready for minimal power draws."
