Corsair RMi series power supplies are 80 PLUS Gold certified and give you extremely tight voltage regulation, virtually silent operation, and a fully modular cable set. With all Japanese 105°C capacitors, they’re a great choice for high-performance PCs where reliability is essential. Corsair iCUE makes it easy to monitor power supply performance, toggle single rail or multi-rail mode, and control fan speed directly from your desktop.
80 PLUS Gold certified
Gold certification ensures high-efficiency operation for less excess heat and lower operating costs.

100% Japanese 105°C capacitors
Premium internal components ensure solid power delivery and long term reliability.
Zero RPM Fan Mode
The superior energy efficiency of the RMi Series allows for the fan to remain off at low to medium loads for virtually silent operation. And when you’re pushing it hard, the thermally controlled fan adjusts its speed to provide optimal cooling with minimal noise.
Configurable +12V rail
It’s your choice – run it in the default multi-rail +12V mode, or toggle single-rail operation.
