Corsair RM850x - 1850W 80+ Gold Fully Modular Power Supply Unit
MAGNETIC LEVITATION COOLING MEETS HIGH EFFICIENCY
CORSAIR RMx Series fully modular power supplies are built with the highest quality components to deliver 80 PLUS Gold efficient power to your PC with the cooling power of potent Magnetic Levitation fans.
135MM MAGNETIC LEVITATION FAN
Utilizes a magnetic levitation bearing and custom engineered rotors for high performance, low bearing noise, and superior reliability.
HIGH EFFICIENCY
With upwards of 90% peak efficiency, RMx produces less noise and less heat, which means less time worrying and more time gaming.
FULLY MODULAR WITH MULTIPLE EPS12V CONNECTORS
Completely modular cables means you only connect the cables your system needs, and the wide range of included cables adds broad compatibility with modern graphics cards and motherboards. Also compatible with the 12-pin GPU Power Cable for the hottest new GPUs.
ZERO RPM FAN MODE
At low and medium loads the cooling fan switches off entirely for near-silent operation, but once the action picks up, the fan activates, ensuring critical component temps stay in check.
TECHNOLOGY AND RELIABILITY
For consistent, reliable power and superb electrical performance, each RMx Series power supply features a robust resonant LLC topology with DC-DC conversion, and 105°C rated 100% Japanese capacitors. With precise timings, RMx supports Microsoft Modern Standby, ensuring extremely fast wake-from-sleep times and better low-load efficiency.
