Corsair RM Series™ 850 Watt 80 PLUS® Gold Certified Fully Modular PSU (RM850)
Corsair RM Series™ 850 Watt 80 PLUS® Gold Certified Fully Modular PSU (RM850)
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.
TUNED FOR LOW NOISE OPERATION
A 135mm rifle bearing fan coupled 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, hence 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.
MULTIPLE-GPU READY
PCI-E connectors to power dual or triple (RM850 only) GPUs for your most ambitious PC gaming builds.
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. These durable and flexible cables come in triple-layer mesh paracord sleeving in addition to interlocking cable combs for an easy-to-install, professional looking build.
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.
