Product information

Description

COUGAR GST 750W ATX3.1 is a non-modular desktop power supply delivering 750 W of continuous power with 80 PLUS Gold efficiency (approximately 91%). Designed to meet Intel ATX 3.1 and PCIe 5.1 requirements, this PSU includes a native PCIe 12V-2X6 (12+4 pin) connector for modern graphics cards, a 20+4 pin ATX motherboard connector, and an active 120 mm HDB cooling fan. The unit is engineered to perform reliably in up to 40°C ambient temperature and uses high-quality 105°C Japanese capacitors and a combination of LLC, DC-DC and Tri-Sense regulation to keep voltage within a tight 3% tolerance.

Advantages

The GST 750W provides efficient power conversion with 80 PLUS Gold certification, reducing energy losses and lowering operating costs. Its native ATX 3.1 / PCIe 5.1 connector design supplies stable and direct power to next-generation GPUs without adapters, while passing stringent ATX 3.1 power excursion tests for transient loads. The 120 mm HDB fan and grooved blade design balance airflow and noise, and the use of 105°C Japanese capacitors enhances long-term stability under sustained workloads.

Suitable for

  • Gaming PCs with next-generation graphics cards that require a 12+4 pin power connection
  • Workstations and content-creation systems needing stable 12V delivery under load
  • Compact ATX builds where a non-modular, reliable PSU with ample cable length is acceptable
  • Systems operating in warmer environments (up to 40°C) demanding continuous 750 W output

Key specifications

  • Total power: 750 W continuous output
  • Efficiency: approximately 91% (80 PLUS Gold)
  • Motherboard connector: 20+4 pin ATX
  • Native GPU connector: PCIe 12V-2X6 (12+4 pin) compatible with PCIe 5.1
  • Fan: 120 mm Hydro Dynamic Bearing (HDB), temperature-controlled
  • Operating temperature: designed performance up to 40°C ambient
  • Voltage regulation: LLC + DC-DC + Tri-Sense architecture with ±3% regulation
  • Capacitors: 105°C Japanese capacitors for standby and stability
  • Input voltage: 100–240 V AC, 50/60 Hz
  • Color and finish: black embossed design
  • Weight: approximately 2.01 kg

How to use

Install the COUGAR GST 750W ATX3.1 in a compatible ATX case following standard safety precautions: disconnect power, ground yourself, and mount the PSU securely. Connect the 20+4 pin ATX cable to the motherboard, plug the native 12+4 GPU cable to the graphics card power inlet if required by the GPU, and attach SATA and peripheral connectors to drives and accessories. Ensure cable routing allows sufficient airflow around the 120 mm fan and does not obstruct case ventilation. After connections are verified, power on the system and observe normal POST and stable operation.

Usage recommendations

For reliable performance, use the native 12+4 GPU connector provided and avoid passive adapters. Maintain adequate case airflow and periodic dust cleaning of the 120 mm HDB fan. Use this PSU in systems that require up to 750 W continuous power and operate within the specified ambient temperature range to preserve component lifespan and stability.
