CORSAIR RM850X White Series 850 Watt Power Supply overview

PRISTINE WHITE CASING

Now available in an elegant white finish to make your build truly stand out.

TUNED FOR LOW NOISE OPERATION

A specially set fan curve ensures that, even at full load, fan noise is kept to a minimum.

80 PLUS GOLD CERTIFIED

The RMx White can deliver power with over 90% efficiency, lowering energy consumption, noise, temperatures, and your power bill.

100% ALL JAPANESE CAPACITORS

By using high-end electrolytic capacitors, the RM750x delivers the unwavering power and long-term reliability you’ve come to expect from a CORSAIR power supply.

ZERO RPM FAN MODE

At low and medium loads the RM750x’s cooling fan doesn’t spin until you need it, for near-silent operation.

FULLY MODULAR, FLAT CABLES

Flexible fully modular, flat white cables mean that you only connect the cables your system needs, making clean and tidy builds easier.

TEN-YEAR WARRANTY

CORSAIR offers a ten-year warranty on all RMx series power supplies, your guarantee of reliable operation that will last across several system builds. If you run into any problems during the installation or use of an RMx power supply, CORSAIR global customer support is ready to help.
