## Long description

The Cougar GR 750W power supply is an ATX 3.1-compatible unit certified to 80 PLUS Gold, designed for desktop PCs and next-generation graphics cards. It delivers up to 750 W of continuous power with up to 91% efficiency, supports PCIe 5.1 GPUs via a native 12V-2X6 (12+4 pin) connector, and provides stable operation at ambient temperatures up to 40°C. The fully modular design and compact 140 mm length simplify PC builds while reducing cable clutter.
Advantages
The GR series combines ATX 3.1 compliance and native PCIe 12V-2X6 support to meet Intel and PCIe standards for modern GPUs, including handling power excursion spikes specified by the ATX 3.1 guide. Its 80 PLUS Gold efficiency lowers energy consumption, while a 120 mm rifle-bearing fan with grooved blades balances cooling performance and low noise. Japanese 105°C main capacitors and an LLC + DC-DC + Tri-Sense regulation design provide tight voltage regulation (within 5%) and reliable output under load.
Suitable for
Gaming PCs with PCIe 5.1 graphics cards
Workstations using current and next-generation multi-core CPUs
Compact ATX builds where a 140 mm PSU is preferred
Systems requiring modular cabling to improve airflow and cable management

Use the native 12V-2X6 (12+4 pin) PCIe connector to power PCIe 5.1 graphics cards without adapters; the modular cable design lets you attach only the cables needed for your build. Ensure AC input matches 100–240 V and verify all connections before powering on the system.
Usage recommendations
For reliable operation, use the PSU in well-ventilated cases and maintain ambient temperatures at or below 40°C. Connect only required modular cables to improve airflow, and allow sufficient slack on the 600 mm PCIe cable to avoid strain on connectors during installation.
