TUF Gaming Series Power Supplies bring together military grade components and a robust cooling solution to create a power platform you can trust. High-quality capacitors and chokes undergo a wide variety of tests, including extreme temperatures and vibration tests, to ensure they meet rigorous military specifications. An Axial-tech fan with a double ball bearing design offers more longevity than other types of fans, increasing the life of the product. It is the perfect PSU to fit into a TUF Gaming rig or any design build to run AAA games for years to come.


  • Military Grade Certification: All critical chokes and capacitors in TUF Gaming power supplies are certified to military grade specifications, ensuring reliability over a wide range of temperatures.
  • 2 Times Longer Life: Exemplary cooling is provided by a 135mm fan rotating in a double ball bearing configuration that will last up to twice as long as a conventional bearing design.
  • Protective PCB Coating: A conformal protective coating wraps around the PCB to protect it from short circuits caused by moisture, dust, and debris.
  • 80 Plus Bronze Certification: The high-quality components used in TUF Gaming power supplies ensure efficient and reliable operation worthy of an 80 PLUS Bronze certification. The efficiency also leads to low temperatures within the power source, facilitating an even quieter acoustic profile for Axial-tech's 135mm fan.
  • Axial-tech Fan Design: Originally developed for high-end ROG graphics cards, the Axial-tech fan design features a smaller fan cage that facilitates longer blades and a barrier that increases downward air pressure. For the TUF Gaming series PSUs, we've scaled that layout to 135mm so it keeps things cool at low RPM and produces less noise.
  • 0dB Technology: An integrated driver stops the 135mm fan when the Thermal Design Power (TDP) is below 30%, allowing you to enjoy light gaming in relative silence. Above 30% TDP, the fans turn back on automatically.
  • 6 Year Warranty: We are so confident in the reliability of the TUF Gaming series power supplies that we back them with a 6 year worldwide warranty.
  • Braided Cables: Cables wrapped in black braided sleeves leave your rig looking tactically clean.
