COUGAR Power Supply GEX 1050W ATX3.0 / 80 Plus Gold / Modular

COUGAR GEX1050 is a high-efficiency 1050 W power supply unit with 80 PLUS Gold certification, designed for stable operation in demanding PC systems. It delivers reliable power at ambient temperatures up to 40°C and includes a 20+4 pin ATX connector and long cables suitable for modern motherboards and PCI Express devices. The unit features a top-mounted 135 mm HDB fan, Japanese 105°C electrolytic capacitors, and an LLC + DC-DC Tri-Sense architecture to maintain tight voltage regulation and consistent performance for high-end GPUs such as the GeForce RTX 30 series.

Advantages

The GEX1050 combines high conversion efficiency that meets and exceeds 80 PLUS Gold standards with a quiet cooling solution that includes a 0 dB mode and a noise-optimized 135 mm HDB fan. Built with 105°C Japanese electrolytic capacitors and validated for 40°C operation, the power supply offers durable components and stable outputs with an advertised ±2% voltage regulation across 3.3 V, 5 V and 12 V rails.

Suitable for

• High-end gaming PCs using GeForce RTX 30 series graphics cards
• Workstations for video editing, 3D rendering and multimedia production
• Systems requiring continuous stable power in warm environments (up to 40°C)

How to use

Install the COUGAR GEX1050 into a compatible PC case following standard ATX PSU mounting procedures and connect the 20+4 pin ATX cable to the motherboard. Attach PCIe power connectors to graphics cards as required and route cables to ensure adequate airflow. Ensure the input voltage selector (if present) and mains connection match local supply (100–240 V, 47–63 Hz). Allow space above the unit for the top-mounted fan and verify the 0 dB mode and fan operation through the system BIOS or supplied software if available.

Recommendations

To maximize lifespan and ensure stable operation, use the GEX1050 in cases with good airflow, keep ambient temperatures below 40°C where possible, and perform periodic dust cleaning of the fan and ventilation areas. Match PSU wattage to your system’s peak power draw and use proper PCIe connector combinations for high-power graphics cards.
