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

I will update this review is anything changes but I have used 2 of these in 2 different builds over the last month and both of them worked very well. Super over kill for the builds they went into, because they are pretty much always running in silent mode but the rigs are ready for 30 series GPUs if they ever come back into stock lol.

This power supply unit seems like an excellent choice for white-themed builds, 850w was exactly what I needed to power my new gaming computer properly. Unfortunately, the cables included with the PSU are horrible. All of the cables, especially the 24-pin ATX cable to power the motherboard, are all extremely stiff and look disgusting in any PC build.

Really good

Ive been using Corsair stuff since overclocking the snot out of their ram in 1998. 20 years.

Modularity made my cables much easier to deal with. I always liked corsair stuff.

Easy install. Not noisy.

Easy install... PS is really nice, its just that the cables within the PC are difficult to trace & replace with ones frome the new PS. So far Great Power Supply. Changed from a 600 watt to a 800 watt. Feel safer knowing I now have ample power for pretty much any peripheral I may come across.

Pci is garbo

I just did a new ATX PC build a couple months ago and went with this PSU. So far Im very happy with it. Unlike one other reviewer, mine came fully and professionally packaged. Keep in mind this review is for a PSU that is way over what I need for power in my case - perhaps some of the negative reviewers where it died in a few days needed a higher wattage one.

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!
