Highlights

BUILT TO LAST
The GX II Gold brings a new standard of durability and efficiency to Cooler Master’s lineup of power supply units combined with ATX 3.0 support.

ATX 3.0 support & a durable 12VHPWR cable
Includes ATX 3.0 support and a 90-degree 12+4pin (12VHPWR) PCIe 5.0 connector featuring higher electrical durability, lower temperatures, and improved safety.

CERTIFIED EFFICIENCY
The GX II Gold is certified to achieve more than 90% efficiency at typical loads.

SILENT FAN PERFORMANCE
WITH A ZERO-RPM MODE
A zero-RPM default mode automatically turns the fan on when your PC reaches a specific temperature.

Separated thermal technologies
Separated thermal technologies provide improved thermal performance and a large, high-quality Japanese capacitor features reduced ripple noise and enhanced reliability.​

Fully modular cabling
Modular cabling reduces clutter, increases airflow, and improves overall thermal performance.
