850 W ATX 3.1 PSU for modern builds

The COUGAR GR 850 is a fully modular power supply rated at 850 W and built to the ATX 3.1 standard. It includes a native 12+4-pin PCIe 5.1 connector that can handle 200 % power excursions. The unit targets builders who need dependable delivery for current multi-core platforms and next-generation graphics cards. It fits compact cases with a 140 mm depth.

Gold efficiency and quiet operation at 40 °C

80 PLUS Gold certification confirms up to 91 % efficiency during typical loads, reducing waste heat and electricity draw. A 120 mm rifle-bearing fan with grooved blades runs at an A- Cybenetics noise rating, keeping acoustics low even under sustained demand. The main capacitor is rated for 105 °C, and the unit maintains full output at 40 °C ambient temperature. Platinum Cybenetics efficiency rating applies to this 850 W model.

Fully modular cables simplify cable management

Every cable detaches from the unit, so only the required leads stay inside the chassis. The single 12+4-pin cable connects directly to PCIe 5.1 graphics cards without adapters, eliminating extra junctions that can affect signal quality. Japanese 105 °C main capacitors improve long-term reliability under high thermal stress. No additional software or accessories are bundled.

Questions sur cet article

How do I connect the native 12V-2X6 cable to my PCIe 5.1 graphics card without using an adapter?

Plug the single 12+4-pin cable directly into the card's 12V-2X6 socket; the connector is keyed so it only fits one way, and the PSU side uses the dedicated PCIe 5.1 port on the modular panel.

What component inside the GR 850 is rated for 105 °C and may need replacement after years of heavy load?

The main Japanese capacitor carries a 105 °C rating; under sustained high temperatures it will age faster and is the part most likely to require replacement first.

At what ambient temperature does the 850 W unit still deliver its full rated output without derating?

The power supply is specified to provide the full 850 W continuously at up to 40 °C ambient temperature.
