Premium components for great performance with very low noise

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 Link Digital 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.

The power of Corsair Link Digital

Our advanced desktop application lets you monitor and log fan speed, voltages and power consumption, as well as control fan speed and configure +12V rail operation.
