Customer Ratings & Reviews

I have been using this power supply for my RTX 3080 build and it's been working flawlessly. My previous GA 750W PSU from EVGA was causing my PC to shutdown automatically so I upgraded to this PSU and have not noticed any issues after that.

This is a great power supply. It's fully modular. The best part was Best Buy price matched Amazon. So I saved an additional $10.

Highly efficient, made with great components. I expect a long life out of this thing. Modular cables makes management a cinch, as well as adding the option to swap them out for custom ones. Provides enough power for anything but multi-GPU setups.

Corsair is well known amongst computer enthusiasts as a quality provider of everything from memory modules, cpu cooling solutions, computer cases, and of course power supplies. The RMx series of power supplies will not disappoint even the the most discerning consumer. Highly recommended!

This is one of the best brands I’d go w/ for any computer needs. Power supply doesn’t take much know-how on setting up; it can easily fit into any mid-size pc cases. It comes w/ all the essentials needed to align and adjust into the case. 11/10!

This power supply takes care of my rig without breaking a sweat. It’s really durable and I haven’t had a single problem with that even under intensive load. I would highly recommend this power supply for something in the 850 watt power supply range.

It does exactly what it is supposed to, supplies power to my new build and I'm very happy with the stability and quality.

Overall a 4-star rating. If you have the 3090 or alike I recommend buying 3 additional 8pin cables so you do not need to have bulky wires shown in the case. Overall a good power supply for the price. I paid around $140 after tax when it was on sale. All I needed for my build. My current build is as follows: -3090 ftw3 -280x case -i9-10850k -3600 DDR4 (2x32gb sticks) -z490-I -850 watt p/s -2x LL120 -4xLL140 -240mm aio

Decent piece of equipment easy to hook up and got a lot of help from the geek squad when I woke up

Powers my rig perfectly. Wanted to get something a little nicer to give myself some wiggle room. B550 motherboard Ryzen 5600X CPU EVGA RTX 3060 XC 32GB RAM (2x) 1TB M.2 (2x) 4TB Hard drives

Works great. This is one of the best PSUs out there in the market. It's on Tier-A of LTT's list. I used this to replace my existing CX550M since I got a 3070 which should've worked fine but I wanted to future proof my system.

I like that its modular, doesn't have ketchup and mustard cables adn have had no issues with it so far.

Quiet and it stopped the coil whine my GPU was getting from the dirty power from my old PSU.

I bought this to replace a Thermaltake PC power supply that failed to work correctly with my UPS (in other words, when the power went out, my PC unfortunately immediately turned off--not good.) Tried this one and it solved the problem.

.....well, at least that i could find. this already has excellent reviews all over the web. just buy it and you won't be sorry. it performs well, and is super quiet. no issues pushing everything i could want or need in my computer.

In a world where power supplies are nearly extinct and chip shortages are everywhere this is a great option. Works perfect for mid range gaming machines or servers. I'm using mine in a Nas and it's doing a great job.

Good buy for a powerful build, and is easy enough to set up, but feels like it lacks cord length

Good product with good shipping time. Also has a lot of amazing packaging with good accessories.cables come neatly in a bag which is very high quality. Overall this is just such an amazing product and I highly recommend

Good power delivery and efficiency, had to exchange my first unit because of coil whine though.

Corsair is a trusted brand with a long 10 year warranty. The 850w is optimal capcity for use with the high end 3000 series GPUs from Nvidia - using a 3090 in mine. Completely modular so you cable management is a dream.
