Customer Ratings & Reviews

Needed something more powerful to handle the 3070 I ordered and this has worked perfectly. Comes with more than enough cables in a fancy bag as well.

Corsair power supply's are always reliable. Gold rated and actually in stock. Fully modular so you don't have to deal with a mess of unwanted cables.

Corsair, as always, provides another top quality product. Fan is quiet, and modular form means I only have to use the power wires required for my build, so it stays cable clutter-free!

This power supply is one of the best I’ve had, I really do recommend purchasing this, especially if you’re going to future proof. Amazing quality and all black cables!

Needed to upgrade my power and this thing did the job without any problems. Was an easy set up and came with organized cables for your pc.

Great, high quality PSU. I barely even hear it when it's running. Had to swap due to my old one having a failing fan and I'm glad I went corsair.

Built a nice PC rig for flight simulator as primary purpose. This power supply is a nice addition as one of my components, it fit into the case very nicely without issues and looks great (even though I can’t see it in the rig). Feature I liked best was the “fully modular” design, not having to include unused cables into the rig made overall cable management really easy. All the cables included with this Corsair RMx 850W are very good quality, very happy. Based on reviews and my limited experience thus far, I expect I will see years of great service from this power supply.

This is our second Power Supply we have bought for a new computer my son has built. Comes with more then enough cables to hook everything up

Easy install and plenty of power for my MSI RTX 370 Gaming X Trio and Ryzen 7 5800x. Also comes with plenty of cables that are pretty sturdy.

Power supply is rock solid, runs my 5950x and 3090 perfectly! Fully modular is so worth it!

I've had this PSU since Nov. 2019 and it is working flawlessly. Loved the fact that it is modular which made it easier to connect things in my mini-ATX.

Solid PSU with enough power for high end builds. I love the fact that it's modular so you don't have a bunch of unused cables to try and hide.

I bought another pc and moved my GTX970 into it. I had put a cheap Chinese 650W power supply in it. Under normal use everything was fine, but when I went play games, the speakers would buzz, and the buzzing wasn't tied to the volume of the speakers. Even with the speakers on MUTE it would buzz. I tried several things and then became convinced it was the cheap components of the power supply causing it. I purchased this Corsair and not only is there absolutely no noise while gaming, there's virtually no noise at all from the power supply. Corsair packs it well and the modulars cables come in a nylon bag! It was easy to install and route the wires.

This power supply did the trick. Needed a higher powered supply for my new video card on my Dell. This did the trick. Very quiet and works great!

Very solid power supply. It will be overkill for a basic build, but it's better to have it and not need it than to need it and not have it.

This is a great PSU. Fully modular so you only use the cables you need. Makes cable management much easier. Provides more than enough power for a single GPU high end system.

A good price and the modular design is a must for convenience and flexibility. I like the fact that the fan only comes on under loads.

This bad Larry gets the job done and some. Simple enough. It's powerful. Quiet and cold . My fan never turns on and I draw quite a bit of power from it.

Saves me money on my electric bill going over kill with my battery source ! Don’t go cheap my people, get you a quality battery supply

I like this simple PSU. I thought about other models but this was it for me. It has more than enough power for my build and the modular design is nice.
