Corsair RM850

Corsair’s RM850 (CP-9020196-NA) arrived in 2019 as part of the refreshed RM Series, a fully modular 80 PLUS Gold ATX line with 10‑year warranty and low‑noise design; the official page lists ATX12V v2.52 specs and Modern Standby support.

Positioned in our PSU scale as high_end (Gold, fully modular), it exists to power mainstream-to-high-end ATX builds quietly and cleanly without extras like iCUE telemetry. It suits mid-range gaming and high-end GPU builds with some headroom/overclocking; note it is an ATX12V v2.52 design and lacks a native 12VHPWR lead—newer ATX 3.x models such as Corsair’s RMe/RMx SHIFT add 12V‑2x6 support.
