Maitinimo blokas Cougar GR 850 PSU 80 plus Gold Fully Modular

The Cougar GR 850W is an ATX3.1-compatible, modular power supply rated at 850 W with 80 PLUS Gold efficiency (up to 91%). It supports PCIe 5.1 GPUs through a native 12V-2X6 (12+4 pin) connector and is designed to deliver stable power even at 40°C ambient temperature. The unit uses a 120 mm rifle-bearing fan, Japanese 105°C main capacitors and a compact 140 mm length to fit most PC cases. Certifications include FCC, CE, EAC, UK CA and RoHS.

Advantages

The GR series provides high conversion efficiency to reduce energy consumption and lower operating costs while maintaining stable voltage regulation within ±5%. Its native PCIe 12V-2X6 connector meets ATX 3.1 and PCIe 5.1 standards, enabling reliable power delivery for next-generation graphics cards without adaptors. Fully modular embossed black cables reduce clutter and improve airflow, and the 120 mm grooved-blade rifle-bearing fan balances effective cooling with low noise.

Suitable for

• Gaming and high-performance desktop PCs with PCIe 5.1 graphics cards
• Workstations using multi-core CPUs and demanding GPU workloads

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.

Usage 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.
