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

As described

I received the wrong versión of this product, I was expecting to receive the RM850x which is an updated version and better quality components including the fan, but I got the RM850 instead which is $100 cheaper.

Nuff said

I did not have any problems with the power supply during the installation.The quality is good. It works now in my desktop. No issues so far.

I really haven’t had any problems expect that it can be a lot louder than I’d want. But I can’t really complain when I’m the one stressing the PC

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!

Nvm its good

I had to order a weaker power supply when I built my current rig 3-1/2 years ago, and ended up with a NON-modular 450 due to crypto-mining shortages, and trade embargoes. I knew it was right at the limit of being able to run the rig, but had no choice. It expired over the weekend. This one was a BREEZE to install, and being modular, I will never have to deal with undoing all the wiring again. It is also much quieter. The fan in the other one was noisy and ran constantly. This returned my rig to being completely silent.

The first one was originally doa. The second one i got through warranty worked like a charm. Use that info for what you will.

Vraiment génial pour les projets techno de toutes sortes.
