Corsair RMe Series RM850e (2025) 850W Cybenetics Gold Fully Modular ATX Power Supply / PSU overview

RME SERIES

CORSAIR RMe Series Fully Modular Low-Noise Power Supplies include a dedicated 12V-2x6 GPU power cable, ATX 3.1 certification and PCIe 5.1 compliance, and Cybenetics™ Gold rated efficiency for a quiet, reliable build. The RMe PSUs' compact size also allow for easier cable management.



FULLY MODULAR CABLING

Keep cable clutter down by connecting only the cables your system needs. A native 600W 12V-2x6 GPU connector and multiple 8-pin PCIe connectors mean RMe power supplies more than meet the needs of modern and upcoming GPUs and CPUs.

ATX 3.1 CERTIFIED

The ATX 3.1 standard demands a high level of reliability and power efficiency. While many CORSAIR PSUs meet these requirements, RMe Series PSUs are formally certified for ATX 3.1 compliance. PCIe 5.1 12V-2x6 GPU cables included for use with modern and next-gen graphics cards.



CYBENETICS GOLD CERTIFIED


Steady power output at up to 90% efficiency and Cybenetics™ Gold certified for lower power consumption, less noise, and cooler temperatures.

LOW NOISE OPERATION IN A COMPACT SIZE

A compact 140mm-long casing ensures an easy fit in modern enthusiast PC cases. A 120mm rifle bearing fan with a specially calculated fan curve keeps fan noise down, even when operating at full load.



TECHNOLOGY AND RELIABILITY


For consistent, reliable power and superb electrical performance, each RMe Series power supply features a robust resonant LLC topology with DC-DC conversion and 105° rated industrial-grade capacitors. With precise timings, RMe supports Modern Standby, ensuring extremely fast wake-from-sleep times and better low-load efficiency.

WORLD-CLASS SUPPORT


Our award-winning service means you can enjoy your gear worry-free with a seven year warrantuy.
