Corsair 850W RM Series RM850 PSU, Rifle Bearing Fan, Fully Modular, 80+ Gold
RM Series RM850 — 850 Watt 80 PLUS Gold Certified Fully Modular PSU
CORSAIR RM Series fully modular power supplies deliver consistent 80 PLUS Gold efficient power to your PC, with virtually silent operation.
Ready For Modern Standby
Modern Standby is a 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, as well as maintain a network connection during sleep to continue downloading updates and receive emails and notifications – just like your phone. Best of all, it does this with less overall power consumption.
To make use of Modern Standby, a compatible motherboard and CPU are also required.
80 Plus Gold Certified
The RM Series delivers power at up to 90% efficiency, lowering energy consumption, noise, temperatures, and your power bill.
Using industrial-grade electrolytic capacitors, RM Series power supplies offer the unwavering power and long-term reliability you demand from a CORSAIR power supply.
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.
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.
CORSAIR provides a ten-year warranty on all RM Series power supplies; your guarantee of reliable operation that will last across several system builds. If you need help, CORSAIR customer service and tech support are always on hand.
PCI-E connectors to power dual or triple (RM850 only) GPUs for your most ambitious PC gaming builds.
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.
Add the Finishing Touch
Complement your system's look with CORSAIR Premium Individually Sleeved Type 4 Gen 4 PSU Cables (sold separately), available in seven different colors and patterns.
