Expert Features

  • Next-Generation ATX 3.1 Power: Built for modern high-performance systems, with the transient-load resilience required to handle demanding GPUs and multi-core processors without flinching.
  • Native PCIe 5.1 GPU Support: The dedicated 12V-2X6 connector powers compatible next-generation graphics cards through one direct 12+4-pin cable—no 6+2-pin adapter circus required.
  • ATX 3.1 Power Excursion Testing: Passes the four ATX 3.1 dynamic-load tests; COUGAR publishes 850W-model results of 1,500W for 100μs, 1,350W for 1ms, 1,200W for 10ms, and 900W for 100ms.
  • 80 PLUS Gold Efficiency: Reaches up to 91% conversion efficiency, reducing wasted energy, heat generation, and electricity costs while maintaining stable power delivery.
  • Cybenetics-Certified Performance: The 850W model earns a Platinum Cybenetics efficiency rating and an A- noise rating for independently evaluated power efficiency and acoustics.
  • Fully Modular Cabling: Connect only what your build needs, eliminate cable spaghetti, improve airflow, and make installation or upgrades dramatically cleaner.
  • Quiet 120mm Cooling: COUGAR’s rifle-bearing fan uses grooved blades and an integrated stabilizing ring to reduce flex, turbulence, and unwanted noise.
  • Japanese Main Capacitor: A durable 105°C Japanese main capacitor strengthens reliability under sustained gaming and workstation loads.
  • Tightly Regulated Output: LLC, DC-to-DC, and Tri-Sense regulation across the 3.3V, 5V, and 12V rails maintains voltage regulation within 5% for stable operation.
  • Full Electrical Protection: SCP, OCP, OVP, UVP, OPP, and OTP protection automatically respond to short circuits, excess current, voltage irregularities, overloads, and overheating.
  • 40°C Continuous Performance: Designed to deliver dependable output in ambient operating temperatures reaching 40°C—because serious builds do not live inside laboratory conditions.
  • Compact 140mm Chassis: The short 140mm PSU body fits most ATX cases more easily and leaves valuable room for cables, cooling hardware, and cleaner routing.
  • Embossed Black Finish: Sleek black housing and embossed black cables keep the power section of your build sharp, controlled, and zero-nonsense.
