• Full Electrical Protection: SCP, OCP, OVP, UVP, OPP and OTP.

Fully Modular Cable Design

Unlike the ATLAS models we've just added, the GR 750 is fully modular.

Only the cables required for your particular build need to be connected to the PSU, helping reduce unnecessary cable clutter and making cable routing easier.

That's especially useful in builds where clean cable management and unobstructed airflow are priorities.

Ready for Modern Graphics Cards

The GR 750 conforms to ATX 3.1 and supports the PCIe 5.1 specification.

A native 12V-2X6 (12+4-pin) connector provides direct power connectivity for compatible graphics cards without requiring a traditional 6+2-pin adapter.

COUGAR specifies a 600mm 12V-2X6 cable, providing additional routing flexibility during installation.

Always check the GPU manufacturer's recommended PSU wattage before selecting a power supply.

80 PLUS Gold Efficiency

The GR 750 carries an 80 PLUS Gold certification and is rated for up to 91% power conversion efficiency.

This positions it above the 80 PLUS Bronze ATLAS series for customers looking for a more efficient power supply.

Compact 140mm Design

Despite its 750W output and fully modular construction, the GR 750 measures just 140 × 150 × 86mm.

The compact 140mm length helps make installation and cable management easier across a wide range of compatible PC cases.

120mm Rifle-Bearing Fan

The GR series uses COUGAR's 120mm rifle-bearing fan with grooved blades and an integrated stabilizing ring.

The fan design is intended to minimize blade flex and turbulence while balancing effective cooling with lower operating noise.

Built-In Protection

The GR 750 includes:

• SCP – Short-Circuit Protection
• OCP – Overcurrent Protection
• OVP – Over Voltage Protection
• UVP – Under Voltage Protection
• OPP – Over Power Protection
• OTP – Over Temperature Protection
