## Long description

The COUGAR GEX PRO 650W is a compact, fully modular ATX3.1 power supply delivering up to 650 W of continuous power with 80 PLUS Gold efficiency. Designed to support modern desktop systems and next-generation GPUs, it features a native PCIe 12V-2X6 (12+4 pin) connector for compliant PCIe 5.1 power delivery, a 120 mm Hydro Dynamic Bearing (HDB) fan for quiet cooling, and stable voltage regulation suitable for operation in 40°C ambient conditions. The unit includes fully modular cables in a black embossed finish, a 20+4 pin ATX motherboard connector and operates from 100–240 V, 50/60 Hz input.
Advantages
The GEX PRO 650W combines high conversion efficiency (up to 91%) with compact dimensions and fully modular cabling to reduce clutter and improve airflow in PC builds. Its native 12+4 pin PCIe connector supports modern graphics cards without adaptors, while the HDB 120 mm fan and optimized blade design balance cooling performance and low noise. Tight voltage regulation and high-temperature components contribute to reliable, stable power delivery under sustained loads.
Suitable for
 Gaming desktop systems with mid- to high-range GPUs that require PCIe 12+4 pin power
 Workstations and content-creation PCs needing stable continuous power up to 650 W
 System upgrades where ATX3.1 compatibility and modern connector support are required
 Compact PC builds where a shorter, 140 mm PSU simplifies installation

How to use
Install the PSU into a compatible ATX case with standard mounting points and connect the 20+4 pin cable to the motherboard. Use only the modular cables you need to reduce clutter; attach the native 12+4 PCIe cable directly to supported graphics cards following the card manufacturer's power recommendations. Ensure mains input is within 100–240 V and that the system has adequate case airflow to benefit from the 120 mm fan cooling. Verify all connections before powering on and observe proper grounding and anti-static precautions during installation.
Usage recommendations
Before connecting the PCIe 12+4 pin cable, consult your graphics card documentation for recommended wattage and connector requirements. For quieter operation, maintain case airflow and position intake/exhaust fans to complement the PSU's 120 mm HDB fan. Avoid overloading the PSU beyond its rated continuous power and allow adequate ventilation when operating under sustained high load or elevated ambient temperatures.
