Expert Features
- ATX 3.1 Power Architecture : Built for current and next-generation systems, with the transient-load resilience required by demanding GPUs and multi-core processors.
- Native PCIe 5.1 GPU Power : A dedicated 12V-2X6 connector feeds compatible next-generation graphics cards through one direct 12+4-pin cable without requiring a 6+2-pin adapter.
- Published Power-Excursion Performance : COUGAR lists 850W-model test results of 1,500W for 100μs, 1,350W for 1ms, 1,200W for 10ms, and 900W for 100ms under ATX 3.1 dynamic-load criteria.
- 80 PLUS Gold Efficiency : Reaches up to 91% conversion efficiency, reducing wasted electricity and heat while delivering stable power—yalla, more energy for the build and less for the bill.
- Cybenetics Gold and A+ Ratings : The 850W model carries a Cybenetics Gold efficiency rating and A+ noise rating for independently evaluated electrical and acoustic performance.
- 120mm Hydro-Dynamic-Bearing Fan : COUGAR’s HDB design reduces friction and vibration for greater durability, quieter operation, and efficient cooling.
- Grooved Stabilized Fan Blades : An integrated stabilizing ring minimizes blade flex and turbulence, improving airflow smoothness without unnecessary noise drama.
- Fully Modular Cable System : Install only the cables your build needs to reduce clutter, improve airflow, and make installation or future upgrades cleaner.
- Compact 140mm Chassis : One of COUGAR’s most compact fully modular PSU designs, fitting a wide range of cases while leaving more space for routing and components.
- Tight 2% Voltage Regulation : Refined regulation keeps output exceptionally stable for sensitive, high-performance PC hardware.
- 105°C Japanese Standby Capacitors : Durable Japanese capacitors support stable standby power delivery and long-term electrical reliability.
- 100,000-Hour MTBF : Engineered for extended service life in gaming, workstation, and performance-focused systems.
- Reliable Operation at 40°C : Designed to maintain dependable output at ambient operating temperatures reaching 40°C.
- Complete Electrical Protection : UVP, OCP, SCP, OVP, OTP, and OPP respond automatically to voltage faults, excess current, short circuits, overheating, and overloads.
- Embossed Black Styling : A black enclosure and embossed black modular cables keep the power section controlled, tidy, and visually locked into serious builds.
