The CORSAIR RMe Series RM850e delivers 850 watts of reliable, efficient power with Cybenetics Gold certification and full ATX 3.1 compliance. Designed for modern high-performance builds, it supports PCIe 5.1 with a native 12V-2x6 connector, ensuring compatibility with the latest graphics cards without adapters. A 135mm fan with Zero RPM mode keeps the system silent under light loads, only spinning up when thermal conditions demand it.

Efficiency & Certification

Rated to Cybenetics Gold efficiency standards, the RM850e maintains high efficiency across a wide load range, reducing energy waste and heat output. The ATX 3.1 specification ensures stable power delivery even during the extreme transient loads generated by modern GPUs.

Modular Cabling

Fully modular cable management means you only connect the cables your build requires, keeping the interior clean and airflow unobstructed. All cables are flat and flexible for straightforward routing in both full-tower and compact mid-tower cases.

Reliability & Protection

Comprehensive protection circuitry — including OVP, UVP, OCP, OPP, SCP, and OTP — safeguards your components against electrical faults. The unit is built to operate continuously at full rated load, backed by a 5-year warranty.
