COUGAR Power Supply GEX 850W ATX3.0 / 80 Plus Gold / Modular

The COUGAR Gaming GEX850 850 W power supply unit delivers 850 W of continuous power with 80 PLUS Gold-level efficiency, helping reduce energy consumption. It is designed for desktop PCs and includes a 20+4 pin ATX motherboard connector, multiple SATA power cable lengths (450, 570, 690, 810 mm), and a 60 cm PCI Express power cable. The PSU accepts AC input 100–240 V at 50–60 Hz, uses an active 120 mm cooling fan and measures 160 x 150 x 86 mm.

Advantages

The GEX850 exceeds the 80 PLUS Gold standard with up to 91% efficiency, lowering electricity costs during typical loads. An exclusive 120 mm silent fan and a refined fan frame provide concentrated airflow and reduced vibration for quieter operation. Components are selected for durability: 105°C Japanese capacitors and design validation for operation at 40°C ambient temperature ensure stable long-term performance. The power stage uses LLC, DC-DC conversion and Tri-Sense regulation for tight voltage control within ±3%.

Suitable for

• Gaming desktop PCs requiring an 850 W power supply
• High-performance builds with multiple SATA devices and PCIe cards
