Gold-certified efficiency with extremely tight voltage regulation to deliver superior performance.

Corsair RMx series power supplies give you extremely tight voltage control, quiet operation, Gold-certified efficiency, and a fully modular cable set. Built with all Japanese 105°C capacitors, they’re a great choice for high performance PCs where reliability is essential. 80 PLUS Gold efficiency reduces operating cost and excess heat, and Zero RPM fan mode ensures virtual silence at low and medium loads. And, the fully modular DC cables make builds and upgrades easy, with clean, great-looking results.

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

Since the fan doesn’t turn on until it’s needed, you’ll enjoy virtually silent operation at low and medium loads.

Fully modular cable set

Installation is faster, since you can mount the power supply in the case first, and then attach only the cables you need.
