Corsair today announced an update to its award-winning low-noise RMx series of power supplies with ATX 3.1 compliance, a native ATX 12V-2x6 connector, a manual fan speed control knob, and other improvements. Boasting Gold-certified efficiency (up to 91%) and an A+ noise rating from Cybenetics, the new RMx series includes fully modular, ultra-flexible embossed cables that simplify cable routing even in the most challenging of PC builds. Cooled by a 140 mm Fluid-Dynamic Bearing fan with a magnetic dome structure and a manual fan override knob, the RMx series remains one of the quietest and most reliable power supplies available.

"We're pleased to launch the new RMx Series with an entirely new electrical design that includes a six-layer PCB for better thermal and electrical performance, an upgraded fan, and full ATX 3.1 compliance," said Jon Gerow, Director of Power Supply Research and Development at Corsair. "We're also happy to announce it achieved the Cybenetics Gold rating for efficiency and the A+ rating for audible noise." Each RMx power supply features 100% Japanese electrolytic capacitors and delivers its rated power output at a 50°C ambient temperature, ensuring reliable power and longevity even under high-stress conditions.
 
Available in 750 W, 850 W, and 1000 W models, every RMx Series PSU is fully ATX 3.1 compliant and includes a native 12V-2x6 connector to support both current and future high-end GPUs. The 140 mm FDB fan is PWM controlled and features a half-dome structure that reduces surface friction, resulting in less noise and an improved lifespan. The specially calculated fan curve ensures fanless operation at low loads and minimal noise as power ramps up. Users who wish to override this can do so quickly and easily using the included knob on the rear of the unit.

The RMx Series features fully modular, embossed cables that are sleek and ultra-flexible, capable of making tight bends when connecting to nearly any device within a case, allowing for easy concealment. The 12v-2x6 cable includes low-profile combs for a clean look that compliments your GPU rather than obscuring it. The RMx PSU enclosure is all-new, featuring a stamped, low-restriction fan grill and an improved connector layout with clearer labeling. For users who want a splash of color, the RMx Series is compatible with Corsair Premium Individually Sleeved Type 4 PSU cables and our ARGB PSU cable strips, sold separately.

RMx Series power supplies measure 150 mm x 86 mm x 160 mm and include a wide variety of cables and connectors that vary based on the model purchased.
