Cooler Master GX II Gold 750W ATX 3.0 Power Supply

The GX II Gold 750W power supply delivers ATX 3.0 compatibility with 80+ Gold certified efficiency for modern gaming and workstation builds. This fully modular PSU features a 12VHPWR PCIe 5.0 connector capable of delivering up to 600W directly to high-performance GPUs, ensuring compatibility with the latest graphics cards.

ATX 3.0 Ready with 12VHPWR Connector

Built for next-generation hardware, this PSU includes a 90-degree 12+4pin (12VHPWR) PCIe 5.0 connector with enhanced electrical durability and improved safety features. The angled design facilitates cleaner cable management in compact cases while supporting up to 600W power delivery to demanding graphics cards.

80+ Gold Efficiency Certification

Achieving over 90% efficiency at typical loads, the GX II Gold reduces energy waste and heat generation. The active PFC design ensures stable power delivery across the 100-240V AC input range, making it suitable for global use.

Silent Operation with Zero-RPM Mode

The 120mm hydro dynamic bearing fan operates in zero-RPM mode during low system loads, eliminating noise during light usage. The fan automatically engages when temperatures rise, balancing thermal performance with acoustic comfort.

Fully Modular Cable Design

All cables are detachable, allowing you to connect only what your system requires. This modular approach reduces cable clutter, improves airflow within the chassis, and simplifies installation. The PSU provides comprehensive connectivity including ATX 24-pin, dual EPS (4+4 and 8-pin), four PCIe 6+2 pin connectors, six SATA, and two peripheral 4-pin connectors.

Advanced Thermal Management

Separated thermal technologies optimize heat dissipation across critical components. A large Japanese capacitor reduces ripple noise while enhancing long-term reliability. The compact 160 x 150 x 86mm form factor fits standard ATX cases.

Comprehensive Protection Features

Multiple protection circuits safeguard your components: over-power protection (OPP), over-voltage protection (OVP), over-temperature protection (OTP), over-current protection (OCP), short-circuit protection (SCP), under-voltage protection (UVP), plus surge and inrush protection.

10-Year Warranty Coverage

Backed by a 10-year manufacturer warranty, the GX II Gold demonstrates Cooler Master's confidence in build quality and long-term performance reliability.
