850W ATX 3.1 power supply

The Cooler Master MPM-85F4-AFG-C3B0CUS delivers 850 W of continuous power through a fully modular design. It targets builders who need reliable energy for high-performance graphics cards and multi-core processors. The unit carries 80 PLUS Gold certification and Cybenetics Platinum plus Noise A- ratings. Japanese capacitors and a digital control IC help maintain efficiency above 90% at typical 115V loads.

Check ATX 3.1 compatibility

Verify that your motherboard and chassis support the ATX 3.1 form factor and the 140 x 150 x 86 mm footprint. Ensure the native 12V-2x6 connector reaches your GPU without sharp bends. Confirm that your system’s total power draw stays within the 850 W limit. The fully modular cables let you connect only what the build requires.

Hydrodynamic bearing fan with zero-RPM mode

A hydrodynamic bearing fan runs quietly and stops completely under low load thanks to Smart Thermal Control Mode. The Wave heatsink design directs internal airflow to improve heat dissipation. GPU Shield intelligent current management monitors for abnormal power behaviour and signals issues via LED alerts. These features combine to keep thermals, noise and power draw stable in normal use.
