Corsair revamped the affordable RMe line, with ATX v3.1 compliant units. I will evaluate the second stronger model of the line, with 850W max power, in this review.
The Corsair RM850e ATX v3.1 is (or will be) included in my best ATX v3.x & PCIe 5.x PSU picks article.
The entire RMe line is certified by Cybenetics, with the 850W model achieving a Cybenetics Gold efficiency rating and a Cybenetics LAMBDA-A noise rating, meaning that its average noise output is within 20-25 dBA.
The new RMe units have native 12V-2×6 sockets to meet the Intel ATX v3.1 and PCIe 5.1 standards. Their embossed cables have low-profile combs to make cable management easier and to look nicer, too. A relatively loose speed profile drives the 120mm rifle bearing fan to keep noise output low. Lastly, the PSU’s dimensions are compact, thanks to the restricted depth of the chassis, at 140mm.
A notable price gap exists between the 750W, 850W, and 1000W models.
