CORSAIR RMX SERIES POWER SUPPLY, RM850X, 850 WATT, ATX 3.1, CYBENETICS GOLD CERTIFIED, FULLY MODULAR

Corsair officially announces the new optimized RMX line, award-winning, low-noise power supplies with ATX 3.1 compliance certification, a native ATX 12V-2x6 power connector, a rotary knob for manual fan speed control, and other improvements.

With Gold-certified efficiency (up to 91%) and an A+ noise rating by Cybenetics, the new RMx Series lineup includes fully modular, ultra-flexible cable harnesses that simplify cable routing even in the most challenging PC builds. Featuring a 140mm fluid dynamic bearing cooling fan with a magnetic dome design and a manual fan override knob, the RMx Series lineup continues to be one of the quietest and most reliable power supplies available.

With a Cybenetics Gold rating for efficiency, each RMx power supply features 100% Japanese electrolytic capacitors and delivers its rated output at 50 degrees Celsius (122 degrees Fahrenheit), ensuring reliable power delivery and a long lifespan even under heavy stress. Available in 750W, 850W, and 1000W models, every RMx Series power supply is fully ATX 3.1 compliant and includes a native 12V-2x6 connector to support current and future high-end GPUs.

The 140mm FDB fan features PWM control and a half-dome structure that reduces surface friction, resulting in lower noise and increased durability. The specially calculated fan curve ensures fanless operation at low loads and minimal noise when the power is increased. Users who wish to disable this feature can quickly and easily do so using the included knob on the back of the unit.

The cables are embossed, fully modular, sleek, and ultra-flexible, allowing them to be easily bent to connect to virtually any device inside the case, allowing them to be easily hidden. The 12v-2x6 cable includes low-profile cable combs for a clean, uncluttered look that highlights the GPU rather than obscuring it. The RMx power supply housing is completely new, featuring a molded, low-resistance fan grille and an improved connector layout with clearer labeling. For users who want a pop of color, the RMx Series is compatible with CORSAIR Premium Individually Sleeved Type 4 PSU Cables and our ARGB PSU Cable Strips, sold separately.
