Expert Features

  • 850W High-End Gaming Power : The COUGAR GEX X2 850 delivers a full 850W on the +12V rail, giving powerful gaming CPUs and GPUs a proper high-performance power foundation.
  • 80 PLUS Gold Efficiency : Up to 91% power-conversion efficiency cuts wasted energy and heat while keeping a serious gaming system fed efficiently.
  • Native 12+4-Pin GPU Power : A dedicated 12VHPWR 12+4-pin cable powers compatible PCIe 5.0-class graphics cards directly without relying on a 6+2-pin adapter.
  • ATX 3.0 Power-Excursion Capability : COUGAR states that the GEX X2 passes the ATX 3.0 guide’s transient-power tests, including handling 200% rated-power excursion for 100μs—exactly the kind of behavior modern high-end GPUs can demand.
  • Fully Modular Cable System : Connect only the cables your build needs, reducing cable clutter, improving airflow, and making clean glass-panel gaming builds much easier to execute.
  • Smart Zero-Fan Operation : The 120mm fan remains stopped at lighter loads and activates once PSU load rises above 30%, helping keep idle and low-load operation quieter.
  • 120mm HDB Cooling Fan : COUGAR’s Hydro Dynamic Bearing fan is designed for longer service life, controlled airflow, and lower vibration and noise.
  • 100% Refined Japanese Capacitors : Premium capacitor selection, 100,000-hour MTBF, and tight 2% voltage regulation target stable long-term operation instead of cheap PSU roulette.
  • Compact 140mm Chassis : At only 140mm long, this fully modular 850W unit leaves more room for cable management, drive cages, and airflow in a wide variety of PC cases.
  • Six-Layer Electrical Protection : Built-in UVP, OCP, SCP, OVP, OTP, and OPP protection guards against undervoltage, overcurrent, short circuit, overvoltage, overheating, and excessive load.
