Power supply Cougar GR 850W ATX3.1 PCIe 5.1 80 PLUS Gold, 850 W, 20+4 pin ATX, 120 mm fan, black

ATX 3.1 Compatible, Reliable Power
The COUGAR GR series is an 80 PLUS Gold-certified power supply, delivering reliable performance even at 40°C. Designed with a native PCIe 12V-2X6 connector, it meets Intel ATX 3.1 and PCIe 5.1 standards. As a modular PSU, it efficiently supports next-gen GPUs with a single 12+4-pin cable, reaching up to 91% efficiency. This reduces energy consumption, lowers electricity costs, and ensures stable power delivery.

ATX 3.1 Certified
Designed to support next-generation systems, the COUGAR GR series conforms to the ATX 3.1 standard. Featuring a native 12V-2X6 design, it provides power to the next-generation graphics cards through a single 12+4-pin cable. With an 80 PLUS Gold efficiency rating, it offers high-quality stability, durability, and reliability.

The COUGAR GR series passes the four strict power excursion tests from PSU ATX 3.1 Guide, in which the spike power consumption must bear up to 200% of the rated power for 100μs.

Designed for the Next Generation of GPUs
The COUGAR GR series supports the latest PCIe 5.1 specification: its powerful and stable performance meets the needs of next-generation GPUs, delivering perfect power for next-gen graphics cards.

How to use

Install the Cougar GR PSU into a compatible ATX case, connect the 20+4 pin motherboard cable and any required modular cables (CPU, PCIe, SATA) only as needed. Use the native 12V-2X6 (12+4 pin) PCIe cable to power compatible PCIe 5.1 graphics cards without additional adaptors. Ensure cables have sufficient slack for secure connections and route them to maintain clear airflow. Verify input voltage (100–240 V, 50/60 Hz) and secure all connectors before powering the system.

Recommendations

For reliable long-term operation, place the PSU in a case with adequate ventilation, avoid blocking the fan intake, and perform periodic dust cleaning. When using high-power GPUs, ensure your case and cooling provide sufficient airflow and use only certified connectors supplied with the PSU.
