Cougar's GF-X Series: Powerful & Affordable Power Supplies

The GX-F Series from Cougar

The GX-F Series from Cougar combines high performance, durability and low noise into a compact as well an affordable package. Their impressive efficiency can be seen in the 80Plus Gold certification they were awarded, something that was also achieved thanks to the high-quality components and technology built into GX-F power supplies. At just 15 cm thick, GX-F power supplies are capable of fitting into nearly any case. The GX-F Series from Cougar also utilises fully modular cable management to make installation significantly easier.

80 Plus Gold Efficiency Power Supplies with Powerful Single Rails

With a thickness of just 15 cm the highly compact design includes Cougar's modern DC-DC down-conversion for the +5- and +3.3 Volt rail. Thanks to this type of voltage conversion, GX-F Series power supplies are extremely versatile: Almost the entire rated performance can be delivered to the +12 Volt rail - all while in environmental temperatures of up to 50 degrees.

The GX-F Series from Cougar

Cougar takes the noise produced by mid- and top-end products seriously. To that end the power supply uses a 135 mm fan with quiet hydrodynamic bearings which are then controlled using advanced fan control technology. At low loads the fan spins down to below 550 RPM and in doing so becomes virtually inaudible. The airflow-optimised fan grills also reduce the potential for air turbulence, helping to ensure the highest possible performance. Thanks to Cougar's choice of premium components and built-in electrical fail-safes, Cougar offers the best of both worlds in terms of performance and long-term reliability.

In addition to more precise voltage regulation and lower residual ripple, these protective circuits are also vital for preserving both the power supply as well as other components even in critical situations. With Over- and Undervoltage Protection (OVP, UVP) as well as Overload- (OPP), Overcurrent (OCP) and Short-Circuit (SCP) protection, power supplies in this range are equipped to deal with any eventuality. All in all, the Cougar GX-F represents the gold standard in terms of recommendations for 80 Plus Gold-certified power supplies!
