Corsair RM850, RM Series, 80 Plus Gold Certified, 850 W Fully Modular ATX Power Supply – Black


Ready for Modern Standby

Modern Standby is an upcoming feature for Windows 10 that vastly improves your PC’s sleep and wake functionality. The technology allows your system to wake from sleep more than twice as fast and maintain a network connection during sleep to continue downloading updates and receive notifications.

  1. 80 Plus Certified

    The RM Series delivers power at up to 90% efficiency, lowering energy consumption, noise, temperatures, and your power bill.

  2. 105°C – Rated Capacitors

    Using industrial-grade electrolytic capacitors, RM Series power supplies offer the unwavering power and long-term reliability you demand from a CORSAIR power supply.

  3. Zero RPM Fan Mode

    The RM Series’ cooling fan doesn’t spin until you need it, for near-silent operation at low and medium loads.

Tuned for Low Noise Operation

A 135mm rifle bearing fan with a specially calculated fan curve ensures that fan noise is kept to a minimum, even at full load. When at low and medium loads, the fan stops spinning entirely until it’s needed, resulting in virtually silent operation.

Compact Size

A 160mm-long casing ensures an easy fit in almost all modern enthusiast PC cases, providing more space for cable management and airflow in your chassis.

  1. Ten-Year Warranty

    Corsair provides a ten-year warranty on all RM Series power supplies; your guarantee of reliable operation that will last across several system builds.

  2. Multiple-GPU Ready

    PCI-E connectors to power dual or triple (RM850 only) GPUs for your most ambitious PC gaming builds.

  3. Fully Modular Cables

    Use only the cables you need for quick and easy installation, simplifying routing and cable management. Store your unused cables in the included cable bag.
