Product information

Description

The COUGAR Gaming GST 750 W power supply unit is a non-modular ATX 3.1 PSU with 80 PLUS Gold efficiency designed to deliver stable power for modern desktop systems and next-generation graphics cards. It features a native PCIe 12V-2X6 (12+4) connector, supports PCIe 5.1, and provides up to 91% conversion efficiency. The unit is built to operate reliably in up to 40°C ambient temperature and includes a 120 mm HDB cooling fan and high-quality components such as 105°C Japanese capacitors for stable standby and regulated outputs.

Advantages

The GST 750 W combines ATX 3.1 and PCIe 5.1 compatibility with an 80 PLUS Gold efficiency rating to offer reliable, energy-efficient power delivery. Its native 12V-2X6 connector and 600 mm cable length reduce the need for adapters and lower the risk of poor connections during installation. The 120 mm HDB fan and optimized blade design provide effective cooling with reduced noise, while LLC, DC-DC and Tri-Sense circuitry ensure tight voltage regulation (±3%). The PSU is rated to handle short power excursions defined by the ATX 3.1 guide and is optimized for stable operation in 40°C environments.

Suitable for

Gaming PCs with next-generation GPUs that require PCIe 5.1 power delivery
High-performance workstations needing stable 12V, 5V and 3.3V rails
Builds where energy efficiency and lower electricity costs are desired
Systems installed in warm environments (up to 40°C)

Key specifications

Total power: 750 W
Efficiency: 91% (80 PLUS Gold)
ATX standard: ATX 3.1
PCIe support: PCIe 5.1 with native 12V-2X6 (12+4) connector
Motherboard connector: 20+4 pin ATX
Fan diameter: 120 mm HDB
Operating temperature: up to 40°C
Weight: 2.01 kg
Color: Black

How to use

Install the GST 750 W into a compatible ATX case and connect the 20+4 pin ATX motherboard cable along with required PCIe and peripheral cables. Use the native 12+4 PCIe cable to power supported GPUs without additional adapters. Ensure proper cable routing and secure connections before powering on. The PSU’s temperature-controlled fan will adjust speed according to load and temperature to maintain cooling and noise balance.

Usage recommendations

For reliable operation, verify that your system’s peak power draw stays within the PSU’s rating and that the GPU is compatible with a single 12+4 PCIe connector. Allow adequate airflow in the case and avoid placing the system in environments exceeding 40°C. Regularly inspect cables and connections during maintenance.
