Magnetic levitation cooling meets high efficiency
CORSAIR RMx Series fully modular power supplies are built with the highest quality components to deliver 80 PLUS Gold efficient power to your PC with the cooling power of potent Magnetic Levitation fans.
135mm magnetic levitation fan
Utilizes a magnetic levitation bearing and custom engineered rotors for high performance, low bearing noise, and superior reliability.
With upwards of 90% peak efficiency, RMx produces less noise and less heat, which means less time worrying and more time gaming.
Zero RPM fan mode
At low and medium loads the cooling fan switches off entirely for near-silent operation, but once the action picks up, the fan activates, ensuring critical component temps stay in check.

For consistent, reliable power and superb electrical performance, each RMx Series power supply features a robust resonant LLC topology with DC-DC conversion, and 105°C rated 100% Japanese electrolytic capacitors. With precise timings, RMx supports Microsoft Modern Standby, ensuring extremely fast wake-from-sleep times and better low-load efficiency.
