Customer Ratings & Reviews

modular feature works amazing and super quit and will power my 5070 no problem.

Great quality, quiet, no issues at all since purchase. Would recomend and buy again without question

I purchased this power supply as part of a PC build to get on Windows 11. It's been rock solid and quiet. Also, the fact that it came with so many cabling options, specifically for video cards was very helpful. While it doesn't have a lifetime warranty, a 7 year warranty seems sufficient for aging this computer to the point where I would be looking a doing another refresh.

I replaced my stock psu with this one. It is so much better. There’s also more room since I only use the necessary cables.

The CORSAIR RM850e (ATX 3.1 / PCIe 5.1 version) is an absolute home run for mid-to-high-end PC builds. If you are putting together a modern gaming rig or workstation and want a power supply that eliminates cable clutter while being fully prepared for current and next-gen graphics cards, this is the one to get.

Saved my live stream my old one was fried got me back up and running its silent and works like it should.

I love it. It’s great it can handle everything runs. Smooth cable wiring is really good.

Build quality is nice and there has been no audible coil whine. The cables are labelled but they would be better with color coded ends as it is easy to mix them up.

This power supply solved a crashing issue I had with my PC. Compared to my old PSU this unit feels super premium and I love how the cables it comes with are white when you get the white unit.

High quality. Works great and is able to power my pc without any issues.

Bought this to replace my faulty msi power supply that the fan went out on after only less than 5 months. This thing is extremely quiet and does not have any vibration at all. it does make a single click noise though when you turn on your pc not sure what thats about but when its running i dont hear it at all.

Originally bought because my pc kept crashing mid game, and that when I found out my 750 battery wasnt pushing enough power out. Bought this 850 & installed it & now it runs alot smoother & quieter, co compared to my original 750 battery

Super quiet and very powerful, compatible with all the latest motherboards and GPUs.

Excellent power supply. The cables are nice and braided

this psu is awesome. fully modular, and super silent

Not too much to say about this psu, especially anything bad. Very clean with an all white build, sturdy perfectly matching white cables, and should be able to power the setup it’s meant to fit years to come.

Amd has low power draw from its builds. So 850W gold standard gets all the love. Warranty and ease of mind from Corsair.

Works great easy for cable management. Work efficiently and very quiet

Very good power supply and a brand that I trust most! Never had an issue with Corsairs power supply when building all my computers. This is always the way to go in my opinion!

Power supply is doing it's job. No complaints and nothing I've noticed out of the ordinary. Corsair does a pretty good job when it comes to their PSUs.
