The CORSAIR RM850e is an 850W ATX 3.1 power supply in the Platinum efficiency tier, with a fully modular cable design and a ThermalProtect 12V-2x6 cable included for GPU protection. It is Cybenetics Platinum-certified and features a Zero RPM Mode for quiet operation at low and moderate loads.

Efficiency & Modularity

• Cybenetics Platinum-certified efficiency, with steady power output at up to 91% efficiency.
• Fully modular design, so you connect only the cables your system needs.
• ATX 3.1 certified and PCIe 5.1 compliant, with a native 12V-2x6 GPU connector.
• Ultra-flexible debossed cables with low-profile combs.
