Cougar GX-F PSU – Top Quality and High Performance

COUGAR GX-F is a high-quality 80 PLUS Gold certified PSU with flawless power delivery in 50°C environments. Compact, efficient, silent and durable, GX-F is the best answer for those looking for the best value in PSUs.


Efficient: A True Money-Saver

To help you save money on your electricity bill, GX-F features a highly efficient design that surpasses the 80 PLUS standard’s requirements.



To protect your investment, two key features have been included in GX-F.

First, GX-F’s LLC, DC-DC and Tri-Sense(3.3V, 5V, and 12V) design has been created to provide high-quality outputs, with an extremely tight 3% voltage regulation to deliver a stabler operation.

Second, it includes 105ºC Japanese main and standby capacitors to ensure that it will keep providing your computer with stable electrical supply for a long time.

GX-F has been designed and thoroughly tested to perform optimally in 50ºC working temperature environments.


135mm HDB Fan

A key component of GX-F is its 135mm HDB fan. Using COUGAR’s patented groove design, this advanced fan’s blade curvature has been fine-tuned to reduce vibration, helping you enjoy a quieter gaming experience.

The HDB technology further extends the fan’s lifespan and reduces acoustic output from the PSU.

COUGAR 135mm Hydro-Dynamic-Bearing Fan

The internal 135mm HDB fan optimizes the balance between RPM and noise.


COUGAR Xformer + Refined Quality

COUGAR Xformer: This high-frequency transformer reduces copper loss and adapts to rising temperatures, while its PQ-Type core further increases efficiency and reliability while keeping the temperature under control.
Streamlined PCB wave soldering: A precise board-to-board connection improves the GX-F’s internal structure, eliminating intermediate cables that produce electrical losses and further enhancing its efficiency.

  • UVP (Under Voltage Protection)If the voltages fall below a certain tolerance value on the single lines, the PSU automatically switches off.
  • OCP (Overcurrent Protection)If the current on a single line is higher than indicated, the PSU automatically switches off.
  • SCP (Short-Circuit Protection)In the case of a short-circuit, this feature prevents damage to the core components of the PSU and its System components.
  • OVP (Over Voltage Protection)If the voltages increase above a certain tolerance value on the single lines, the PSU automatically switches off.
  • OTP (Over Temperature Protection)If the temperature gets too high, the PSU automatically switches off.
  • OPP (Over Power Protection)If the system is oversized and requires more power from the PSU than it can provide, this protection function is activated.
