Customer Ratings & Reviews

Works perfectly and is able to fully power a 5070 GPU or any you might have in your PC. The ability to dial the fan as well or just have it function on automatic is a really nice feature.

Had this PSU for about a little over a month now and it performs extremely well. I was a little worried about the heat output, but the adjustable fan control is a nice addition to help you maintain lower temps woth higher loads. That being said, I typically keep the dial in the "off" position that way the auto fan control takes over and I can keep noise to a minimum. Overall. Very solid purchase and Corsair continues to impress

This is a good PSU made by a good PSU company. It is ATX 3.1 compliant, which means it will come with the necessary bits to hook up your shiny new graphics card without popping the cable (provided the user plugs everything in correctly). Solid form factor, generous cable lengths, basically everything you would expect from a good PSU purchase.

So far, so good. I've used Corsair power supplies in the past and had good luck with them. I was happy to see the size of the fan as the larger fan is much quieter. The build that I used this in for reference is an asus main board with a Ryzen 7 9700x paired with an rtx 3080. I was able to add 7 140mm fans to the case for good airflow. Result is a system that is very quite and is really only noticable when gaming, and even then not as loud as the PC my son has. Overall I'm happy with the power supply and would recommend. If you want to run more than a single video card you may need a larger power supply. There are websites that you can use to virtually build your system and get an idea whether it will adequately support your planned system to both number of connections and wattage wise. A word of warning though for modular power supplies. Bag and tag your extra cables and mark for power supply. Some older Corsair cables that fit the slots are wired differently and can fry equipment if you use them

Awesome PSU. very quiet, runs cool, and no problems at all curing set up or during operation.

Love it. It is a lot quieter then my old one. I love how I can adjust the speed

Works great . Easy install for a new pc builder! Modular so you use what you need. Good fir cable management!

so easy to install! and cut out having to use a lot of unnecessary wires!

Great PSU after doing research I found this was a highly rated power supply. I really like the adjustable fan knob I put it at lowest setting so it's always running. It's replacing only a 3 year old EVGA PSU that went bad and was causing my PC to crash. After I installed the Corsair no more crashes!

Quiet, easy to install, no issues and best of all; it works

Easy to install and fully modular, easy for anyone who hasn’t installed a modular before.

Very nice power supply rates extremely well for protection on your computer from brown outs and consistency. 850w is more than I'll ever need. Corsair is a great company that stands behind their product as well. I had an old version that I had to RMA it was 6 years old and no question asked they sent a replacement. I really like this brand

Great PSU. The manual fan knob is an interesting feature but if placement of the tower doeant make that accessible, its not very usable. The cable management is great with the fully modular design. Very quiet as well.

I have been a corsair power supply guy for several years now. I was initially a EVGA guy but made the jump over and so far haven't gone wrong. I end up buying this unit for the new nvidia power connection. Stored the previous RM850e I had as a backup or for when I upgrade the wife pc in the future. This power supply is powering a 7800x3d, 32gb of ddr5 on a Asus B650e board, asus tuf 5700ti and all the other usual stuff.

ATX 3.1 power standard from Intel, RMx PSUs have the connections needed to power today’s demanding PC hardware including a native 12V-2x6 connector. 100% Japanese 105°C-rated electrolytic capacitors deliver fantastic electrical performance, while a 140mm FDB fan provides low noise cooling. Backed by a ten-year warranty, RMx PSUs are the gold standard for many years to come.

Got this unit for a new PC build. I have used Corsair products before and never had any issues. This new power supply is great as it is totally modular and you can use only the cables that you need leading to a cleaner look and easier cable management. Would definitely buy again.

Very nice PSU. Like the nicely finished cables with separators. Had a little "new" smell with first use under power, but that went away quickly. All in all, I can recommend this PSU.

Was having trouble with my desk top crashing all the time. Then i bought a new graphics card and had Bestbuy install it. They advised me I needed a new power supply unit to support the new graphics card. I agreed it was necessary to run my new Cinema 4d app. They installed itand I have not had a single crash since that. Very happy guy today

This thing is a beast. It is crucial for my pc, which is fully decked out with Corsair. I have 10 Corsair fans, 128 GB of Corsair RAM, and a Corsair AIO cooler. Other Corsair peripherals that I have are a Corsair XL Extended mouse pad, a Corsair wireless charging pad, which is used to charge my Corsair mouse! This PSU is a must-have!! Try it out for yourself! Corsair never disappoints!

Running a RTX 3060 video card and this run its beautifuly. Also really like the clean look of the wiring. Makes it easy to route and manage.
