Product details

The Corsair RM850 is fully modular, optimized for a quiet environment, and powerful. It is built with low-noise capacitors and transformers, and with the Zero RPM Fan Mode, the fan only starts spinning under high load.

Thanks to the fan's special design for quiet operation, it remains extremely silent even under heavy use. The 80 PLUS Gold efficiency certification leads to savings on your electricity bill, and the black low-profile cables are completely modular.
