Product information

Description

The Corsair RM850x 850 W is a fully modular ATX 3.1-compliant power supply designed to deliver stable power to high-performance PCs. It features 80 PLUS Gold efficiency, a native 12V-2x6 GPU cable for modern graphics cards, low-noise operation with Zero RPM mode, and 100% industrial-grade Japanese 105°C electrolytic capacitors for extended reliability. The unit supports continuous operation up to 50°C and includes a 140 mm fluid-dynamic-bearing fan with a manual fan override knob.

Advantages

The RM850x combines high efficiency (80 PLUS Gold) with low-noise characteristics thanks to a 140 mm fluid dynamic bearing fan and Zero RPM mode. Full modularity reduces cable clutter and simplifies installation, while 105°C-rated Japanese capacitors and 50°C continuous operating temperature ensure long-term stability under load. ATX 3.1 certification guarantees compatibility with current CPU/GPU power states and modern sleep/hibernate modes.

Suitable for

  • High-performance gaming PCs with NVIDIA GeForce RTX 40 Series or similar GPUs
  • Workstations requiring stable 850 W power delivery
  • PC builds where low noise and clean cable management are priorities
  • Systems operating in warm environments (up to 50°C continuous)

Key specifications

  • Total power: 850 W
  • Efficiency: 80 PLUS Gold (around 90% typical)
  • ATX compliance: ATX 3.1 certified
  • Motherboard connector: 24-pin ATX
  • Fan: 140 mm fluid dynamic bearing with Zero RPM mode
  • Capacitors: 100% Japanese electrolytic, 105°C rated
  • Included GPU cable: native 12V-2x6 pin
  • AC input: 100–240 V, 47–63 Hz
  • Colour: Black
  • Weight: 3.28 kg
  • MPN: CP-9020270-EU
  • EAN: 840006667445

How to use

Install the RM850x into a compatible ATX case and connect the 24-pin ATX motherboard cable, CPU and PCIe power connectors, and storage/peripheral power cables as required. Use only the modular cables provided or specified by the manufacturer. If your GPU requires a native 12V-2x6 connector, use the included cable. Ensure AC input matches the local mains (100–240 V). For quieter operation, leave the power supply to manage fan speed automatically; use the manual fan override knob only when additional airflow is needed.

Usage recommendations

Place the PSU so its fan intake and exhaust are unobstructed, maintain good case airflow, and avoid exposing the unit to temperatures above 50°C for prolonged periods. Use the modular cables to route power cleanly and check compatibility with your motherboard and GPU before installation.
