Fully Modular Cable Design

The GR 850 is fully modular, allowing you to connect only the power cables required for your particular PC.

Fewer unused cables inside the case can simplify installation and make it easier to achieve clean cable management.

Ready for Modern Graphics Cards

The GR 850 supports ATX 3.1 and PCIe 5.1 and includes a native 12V-2X6 (12+4-pin) connector for compatible graphics cards.

COUGAR specifies a 600mm 12V-2X6 cable, providing additional routing flexibility when connecting compatible GPUs.

80 PLUS Gold + Cybenetics Platinum

The GR 850 carries 80 PLUS Gold certification and is rated for up to 91% power conversion efficiency.

The 850W model additionally earns a Cybenetics Platinum efficiency rating, providing another independent efficiency certification beyond 80 PLUS.

Cybenetics A- Noise Rating

The GR 850 also carries a Cybenetics A- noise rating.

Cooling is handled by COUGAR's 120mm rifle-bearing fan, featuring grooved fan blades and an integrated stabilizing ring designed to reduce blade flex and turbulence during operation.

Stable Power Delivery

The GR 850's single +12V rail provides up to 70.8A / 849.6W, supporting the demanding power requirements of compatible modern hardware.

A 105°C Japanese main capacitor is used to support reliable and durable power delivery.

Built-In Protection

The GR 850 includes:

• SCP – Short-Circuit Protection
• OCP – Overcurrent Protection
• OVP – Over Voltage Protection
• UVP – Under Voltage Protection
• OPP – Over Power Protection
• OTP – Over Temperature Protection
