Keep cable clutter down by connecting only the cables your system needs and nothing else. Five universal 8-pin connectors can be used with any 8-pin cable, satisfying all the power needs of modern motherboards and GPUs.


A 120mm rifle bearing fan with a specially calculated fan curve keeps fan noise down, even when operating at full load.
With Zero RPM Fan Mode for near-silent operation at lower loads.


For consistent, reliable power and superb electrical performance, each RMe Series power supply features a robust resonant LLC topology with DC-DC conversion and 105° rated industrial-grade capacitors.

With precise timings, RMe supports Modern Standby, ensuring extremely fast wake-from-sleep times and better low-load efficiency.


Steady power output at up to 90% efficiency, and Cybenetics Platinum certified for lower power consumption, less noise, and cooler temperatures.
