Product information

Description

The CORSAIR RMx Shift Series RM850x is an 850 W ATX power supply designed for desktop PCs. It delivers efficient, stable power with 80 PLUS Gold efficiency and supports 100–240 V AC input at 47–63 Hz. The unit includes a 24-pin ATX motherboard connector, fully modular Type-5 cable connections, and an active 140 mm fluid dynamic bearing fan for cooling. Cable lengths include SATA runs of 100 mm, 500 mm and 700 mm and a 610 mm motherboard cable.

Advantages

The RM850x combines Cybenetics Gold certification (up to 89% overall efficiency) with ATX 3.1 compliance and PCIe 5.1 readiness for modern graphics cards. Its side-mounted Type-5 connectors and fully modular cable system reduce clutter and simplify cable management. Included are ultra-flexible debossed-PVC cables and low-profile combs for a tidy build, and a manual fan speed control knob that lets you override Zero RPM Mode to increase airflow when needed.

Suitable for

  • High-performance gaming PCs with modern GPUs (NVIDIA GeForce RTX 50 Series and similar)
  • Workstations requiring stable 12V power and ATX 3.1 features
  • Compact or clean builds where cable management and reduced clutter are important
  • Systems needing near-silent operation at low-to-medium loads

Key specifications

  • Wattage: 850 W
  • Efficiency: 80 PLUS Gold; Cybenetics Gold certified (up to ~89% efficiency)
  • ATX standard: ATX 3.1 compliant
  • PCIe: PCIe 5.1 ready; native 12V-2x6 GPU power cable included
  • Connectors: 24-pin ATX motherboard connector; fully modular Type-5 connectors
  • Fan: 140 mm fluid dynamic bearing, Zero RPM Mode, manual fan speed control knob
  • Capacitors: 105°C-rated Japanese electrolytic capacitors
  • Input voltage / frequency: 100–240 V, 47–63 Hz
  • Color: Black

How to use

Install the RM850x in a compatible ATX case and connect the 24-pin ATX cable to the motherboard. Use the fully modular Type-5 connectors to attach only the cables required for your build, including the native 12V-2x6 GPU cable for supported graphics cards. Route the included debossed-PVC cables with the low-profile combs for a neat layout. Adjust the fan behavior with the manual fan speed control knob when additional cooling or airflow is required; otherwise allow Zero RPM Mode to operate for near-silent performance at light loads.

Usage recommendations

For optimal reliability, ensure adequate case ventilation and use the manual fan override only when sustained higher airflow is needed. Verify GPU compatibility with the native 12V-2x6 connector and follow manufacturer instructions when connecting power cables.
