Corsair RM Series power supplies are fully modular and optimized for silence and high efficiency. Zero RPM Fan Mode means that the fan doesn't even spin until the power supply is under heavy load, and the fan is custom-designed for low noise operation even at high loads. 80 PLUS Gold rated efficiency saves you money on your power bill, and the flat black cables are fully modular, so you can enjoy fast, neat builds. And, like all Corsair power supplies, RM Series is built with high-quality components and is guaranteed to deliver clean, stable, continuous power. Connect it to your Corsair Link system and you can even monitor fan speed and +12V current directly from your desktop (additional cable required for 450W-850W units).

Optimized for Silence

The efficient design of the RM Series means minimal excess heat generation, and thanks to the Zero RPM fan mode the fan doesn't even need to spin under low to medium loads. The custom-designed fan has an optimized blade profile for low-turbulence airflow and near-silent operation even at full speed. And when you're pushing it hard, the thermal sensor controls the fan speed to ensure that it gets the cooling it needs without any extra noise.

The components used to manufacture the RM Series are manufactured specifically for excellent performance and low audible noise.

80 PLUS Gold-certified Efficiency

Highly efficient RM Series power supplies produce less heat and have lower operating costs.

Flat black, Low-Profile Modular Cables

You can use only the cables you need, and leave the rest in the box for fast, easy, and great-looking builds.

Reliable, Continuous Power Delivery

RM Series power ratings are continuous, not peak, for superior protection for your valuable PC. Corsair uses high-quality internal components, and RM Series power supplies are guaranteed to deliver clean, stable, continuous power.

Corsair Link Compatible
