Corsair RMX Series, RM850x, 850 Watt, 80+ Gold Certified, Fully Modular Power Supply (Low Noise, Zero RPM Fan Mode, 105°C Capacitors, Fully Modular Cables, Compact Size) Black

awesome power!!!

We have purchased 3 of these power supplies over the past two years for new builds and rebuilds. We have had no issues, its the go to power supply!

I bought this after my old one decided to stop functioning during certain games and installed this one instead. This PSUs SATA power cables solved a lot of space issues as my case doesnt have very much room for cable management, but many of the cables that come with this PSU are flat and easy to manage / squeeze into any case. My last corsair PSU lasted me about 5 years, hoping this one lasts longer!

Corsair makes excellent PSUs. Definitely cant complain. Its not my first build with Corsair PSUs that outlive their warranty. Cant say that about some other brands.

Had a Master Cooler that made noises and vibrations, as well as causing my PC to restart itself in the middle of gaming. Every day. After a year of using it. So I bought this and all is well. Quiet as a mouse, everything works as it should, and I don’t lose all my progress on Star Citizen due to my PSU being a hunk of garbage. Highly recommend. Never had an issue with anything Corsair.

buy bigger than you need and it will stay virtually silent. great quality!

Product is good. Easy to install and quiet. Shipping from amazon terrible. They are using the original box to ship which is not meant for that purpose. The first attempt resulted in a significantly damaged box and broken product seals. Despite assurances from Amazon customer support that the replacement would come in an amazon box the same thing happened. At that point i was desperate to repair my PC and had no choice but to use it. My bottom line is good product but purchase somewhere else until Amazon resolves the shipping issue... especially if its time sensitive

All modular and easy to install. I never had a Corsair component fail. Ive bought 8 in the past 10 years in my builds, all still work.

When motherboard needs to power on it just clicks and shuts off. Cross checked with a working PS and everything was fine.

Thank you Corsair.
