Corsair RMX White Series (2018), RM850x, 850 Watt, 80+ Gold Certified, Fully Modular Power Supply - White, 80 PLUS Gold (CP-9020188-NA)

Bought this Oct.24, 2020 and installed it as soon as it arrived a few days later. Today (May 24, 2021) it died on me. What a piece of junk! I will never buy a Corsair item ever again!

Works like it said it would!

It is a good upgrade for my gaming computer.

My husband’s job is in the computer engineering field, and we own many, many computer-related items. He saw this and had to have it. He said he wanted it to replace the OEM power supply in an eight year old Dell Optiplex 790 that has been running FreeBSD 24/7 as a lightweight personal server. He stress tested it for two weeks with regular load plus power intensive CPU and hard drive loads using the stress-ng utility and observed no problems or excessive noise. My husband really likes that this has modular cables because there are no unused/spares to tie up out of way or to block airflow. This supply’s connectors are tight and have a thumb-clip to hold it/them in place. When powered-on, the fan spins up then turns off in less than a minute in what Corsair is calling Zero RPM fan mode. However, if a high CPU or hard drive load is imposed on the system the fan spins up again. We like this but would caution that this could cause localized excessive heat (e.g. hard drive) inside any computer cases that are designed with the assumption that the power supply fan is always moving air through the case. When it is on at what is assumed full speed, the 140mm fan is large enough to move a good volume of air fairly quietly. As it isn’t listed what come with this power supply, it includes: 1 modular 24-Pin ATX motherboard power cable, 2 modular cables, each supplying power to three SATA drive power connectors, 1 modular cable that supplies power to four IDE (a.k.a 4-Pin Molex) drive power connector, 2 modular cables, each supplying power to two 6/8 combo PCIe power connectors, 2 modular 8-Pin CPU power cables (EPS12V), 4 black case screws, and 10 black tie-wraps. We are both very happy with this, and I highly recommend it!

I was upgrading to a 3070 so I needed a new power supply. This one seems to run fine and no issues yet. My problem is with the cords, like a lot of others on here. They weren’t necessarily too stiff for me, but specifically the two cord sets of 6+2 are impossible to get to plug in the best way.

Definetly with the purchase

The rm850x makes little to no noise during operation.

easy to install, very nice and quiet!

Added to new computer, working. Does not seem overly loud.

Perfect product, would highly recommend!!!
