Corsair RMx Series RM850x PSU

ATX 3.1, PCIe 5.1, Cybenetics Gold-Certified, Fully Modular Corsair RMx ATX Series

CORSAIR RMx Series has powered top-performing PCs for years. These fully modular, low-noise PSUs are Cybenetics Gold-certified for lower power consumption, less noise, and cooler temperatures. Fully modular cables make PC building easy, as you only connect the cables your system requires. Additionally, the RMx Series' extremely flexible embossed cables make installing and connecting the PSU easier.

RMx PSUs are compatible with the ATX 3.1 power standard from Intel®, and support the PCIe Gen 5 platform. An native 12V-2x6 connector ensures compatibility with the latest graphics cards with a direct GPU-to-PSU connection, without the need for an adapter. With 100% Japanese 105°C-rated electrolytic capacitors, the electrical performance of the RMx Series is outstanding.

Keep noise levels down thanks to a 140mm proprietary FDB fan, which uses a specially calculated fan curve for low-noise operation even at full load. A built-in fan speed adjustment knob on the back of the PSU also gives you quick manual control. At low loads, support for Zero RPM fan mode results in virtually silent operation. With a maximum operating temperature of 50°C, an RMx PSU can handle all the stress you can throw at it.

Backed by a ten-year warranty, the CORSAIR RMx Series will be the gold standard for many years to come.
