80 PLUS GOLD Efficiency and extremely tight voltage regulation, now with a new look.

CORSAIR RMx White Series power supplies give you extremely tight voltage control, quiet operation, 80 PLUS® Gold-certified efficiency and all new white casing and fully modular cabling.

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, while Zero RPM fan mode ensures virtual silence at low and medium loads. With a new clean white exterior and white fully modular individually sleeved cables, it's now easy to match your system's style and use only the cables you need with clean, great-looking results.

We're so confident in the RMx family, we give it a 10 year warranty. Plug it in, turn it on, and game on.

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.

Ten year warranty

Your guarantee of reliable operation that will last across several system builds.

Fully modular cable set

The included CORSAIR Premium Individually Sleeved cable kit features paracord sleeves on every cable, as well as in-line capacitors on the ATX 24-pin, EPS12V/ATX12V, and PCIe cables that reduce ripple and noise, ensuring clean voltage. A set of cable combs for the 24-pin, EPS12V/ATX12V, and PCIe are also included.

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