Upgraded PSU’s and I haven’t heard a peep out of this one! Was very easy to install.

good price, works great, and has high quality japan capacitors

Had to replace mine and this one has been amazing and was very easy to install!

i purchased this power supply for a brand new pc build with a new Ryzen 9900x cpu and MSI Mag 870e MB. This 850 watt power supply has lived up to my expectations and has blended in nicely with my new setup.

This affordable power supply was great and just what i needed for my 5080

This is such a good psu for what it’s worth. If you’re building a pc, get this.

It's a Power supply, Bought it in a pinch, Thought mine had died but after i found out that mine was fine, i chose to keep it, even in a gaming load the fan will not spin. Feels very nice to install and is very competitively priced @ $145 (after tax)

quiet and was pretty simple to set up. better if you can get it on sale though.

I always get the RMx version of Corsair's power supply. Very dependable and very modular

Purchased this power supply for my first build back in 2021 and it's still running just as good as it did the day I bought it! 10/10 would recommend and will continue to purchase Corsair PSUs.

Had to go thru 2 other Power supplies before I got this one because the 9070 XT Gigabyte Gaming OC needs x3 8pin connectors & the other power supply’s only had 2 of them. Also cable management on this PSU is great! I thought about buying cable extensions but after opening the box I was supper happy with how the included cables looked that I did not need to buy the extensions.

Great power supply for my pc. Gave me enough headroom to upgrade in the future!

Very well built and very low sound level. Many parts included to make sure connecting is not a issue

Corsair makes quality power supplies. The RMx series uses quality components and this is no exception. Although you’ll hardly ever see it in ur case, it pairs well and matches the Corsair Frame 4000D case.

High quality with no issues. Getting modular is so much better and the cables provided are of extreme quality, like the PSU itself. Would definitely buy again!

I am using the RM850x PSU in my new build with 9900x and 5080 FE. It includes the 12VHPWR connector required for 5080FE. The PSU is almost silent even during heavy gaming.

Truly fantastic. This is the 2024 refresh (if memory serves), with the 12V-2x6 native for the newest generation of GPUs. You really can't go wrong with the Corsair RMx series. Completely recommend.

This is really a great PSU and was a replacement for the exact same model in my current system. I was very glad that bestbuy had a unit given that my computer is 6 years old. Good job keep it up!

First class power supply that meets all my needs with room for expansion.

I like the cables and how simple it was to set this PSU up. 2 months later and it's still doing it's job. Cables are decent length and flexible.
