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

Love the psu. More than enough for a simple build. Modular design enables you to put exactly what cables you need, making cable management MUCH easier and cleaner.

the product doesn’t work and it took amazon nearly two months to refund me and resolve the issue. DO NOT BUY.

Was a solid buy for the all white Lian Li case build Im working on fits great and cables white is perfect, not a off white or anything of the sort a nice true white case with a lot of pins 8-8 and etc.

Fair warning, if you notice that the fan doesnt spin while at Idle, dont freak out. The fan kicks in once its under load. Its also really quiet , like I cant hear it even when the fan is going. Way better than my old OCZ PSU, so Corsairs quality is great.

This powers my build perfectly.

The first thing that sets this power supply apart from others is the heavyweight metal housing, and the tough black powder coating. OEM and budget power supplies come housed in flimsy metal, so CORSAIR has an immediate advantage in the visual and tactile quality test. Looks and feel arent everything, but theyre a good start. Also, by personal choice, I am a big fan of the clean black appearance with only white for labeling, and the all-black cables included. It really adds to the look of a finished build; gone are the rainbow cables from the past.

I used this Corsair RM650 to upgrade the PSU in a gaming computer that I originally thought didnt need a PSU of more than 500 Watts. Now, a couple of years later I want to add a new video card, and an upgrade was necessary. This PSU is of superior quality, well-designed and constructed, with good materials, and the modular feature keep the interior of the case organized, and it also it lets more space for ventilation. Because one only has to install the cables that are being used. The modular design also makes it easier to install, and I could notice an improvement in performance, which I wasnt expecting. I simply wanted to have the voltage to handle the new GPU, but it has improved the machine altogether.

They are proven reliable and long lasting. I wouldnt buy anything buy a Corsair PSU for any of my builds. It doesnt matter which model as long as your power requirements line up, pull the trigger. I highly highly recommend Corsair PSUs and they are the only PSUs that I will ever use!!

First order worked great until the fan kicked in for the first time and had a wonky fan bearing that caused the fan to rattle and hit the fan grill making a ton of noise. The second one looked good at first inspection but upon powering up it died, and took my motherboard with it. Waiting on replacement motherboard now to see if it fried anything else. My GPU survived but no idea on RAM, CPU, NVME drive, or any of my SATA devices (HDD, SSD, Fan controller, Cooler) until the new board gets here. I would **HIGHLY** recommend you dont bother with this supply and get an EVGA one instead. You can buy white cable extenders for 30-50 bucks depending on quality and not have to deal with the bs.

Corsair quality always on point. I saw some negative reviews about this and was concerned about ordering this but since it wasn’t available it Best Buy or anywhere else I decided to order from Amazon and I am happy to say I got it in a perfect condition and it works perfectly no coil noise under pressure or super quiet when idle. Build quality is solid as well. Price was decent it was msrp I mean nothing is msrp at this moment but it’s fine I think I got a good deal considering the chip shortage around the world.. very happy now let’s see how long does it last without giving me any trouble that’s the real test.. I will update the review if I ever get any problems with it.
