STRENGTH IN ELEGANCE
Cooler Master presents the GX III Gold featuring exceptional efficiency, low noise output, and superb reliability.
Innovative, streamlined design
The innovative design streamlines the overall aesthetic of the unit and greatly improves airflow.
ATX 3.0 support & a durable 90-degree 12VHPWR cable
Includes ATX 3.0 support and a 90-degree 12+4pin (12VHPWR) PCIe 5.0 connector featuring higher electrical durability, improved safety, and capable of bringing up to 450W to your GPU.
Optimized thermal performance
An anodic-coated heat sink keeps average temperatures 5℃ lower than a traditional heat sink for enhanced durability and a prolonged life span.
CERTIFIED EFFICIENCY
80 Plus Gold and Cybenetics Platinum certifications indicate achievement of more than 90% efficiency at typical loads. This Gold certified unit can also achieve Titanium level efficiency under general light load usage in a 115V test.
SILENT FAN PERFORMANCE WITH A ZERO-RPM MODE
This unit has received a Cybenetics A- noise level certification and includes a smart thermal control mode that defaults to zero spin.
Fully modular cabling
Modular cabling reduces clutter, increases airflow, and improves overall thermal performance.
