Product overview
Corsair’s RM850 belongs to the RM Series (2021 refresh) introduced in 2021. It’s an 850 W, 80 PLUS Gold, fully modular ATX unit with a 140 mm rifle‑bearing fan and a Zero RPM mode. The design follows ATX12V v2.4 and ships with PCIe 6+2‑pin leads only—no native 12VHPWR or ATX 3.0/3.1 compliance.
On our scale it’s high_end: a Gold, fully modular PSU built to power today’s single high‑end GPUs and multi‑connector motherboards quietly and efficiently. It’s a good fit for mid-range gaming and many high-end GPU builds with headroom/overclocking in standard ATX cases. Notable: it includes three EPS12V (CPU 8‑pin) cables for boards that need them.
