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.
  • Patented groove design
  • Centralized oil pressure
  • No oil leakage
  • Improved stability
  • Less friction and noise
  • Extended lifespan
  • 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.
