7.0/10verdict: good, not the best

The Corsair RM850e is an 850W ATX power supply for people building or upgrading a quiet desktop or workstation. It suits buyers who want a fully modular unit with a native 12V-2x6 cable and a seven-year warranty. It is less suited to builds that need many PCIe 8-pin cables or a low-load, always-on setup.

Strengths and weaknesses

Corsair RMe Series RM850e

  • + Quiet: 22.81 dBA average and consistent owner praise
  • + Fully modular with a native 12V-2x6 cable
  • + Ripple and regulation measured well by independent reviewers
  • − Only two PCIe 8-pin connectors
