Customer Ratings & Reviews

This is a fantastic power supply. High quality cabling, very cool and quiet, and more than enough power to run just about anything you throw at it. I'm very happy with my purchase!

Used this in my AMD Ryzen 5 build with Asus ROG motherboard. Well built power supply and plenty of cables like most modular supplies these days. Have had this for about 1 month with zero issues and no complaints.

Another power supply by Corsair. I’ve never had any issues with a Corsair product, maybe I’m lucky or maybe they are just worth it. But I’ll continue using them. Great power, easy to install.

This unit is fully modular and allows you to only use what you need. The unit also comes with a felt bag for the excess cables in the event that you need then in the further. Great product!!

Technically generates 849.6 max watts on the 12V rail. Still a good power supply and 0 RPM mode as long as you're below 50% of the watt rating and isn't too warm. Great for all systems unless you're using it for a high work load server. Best thing with RMx PSUs is you get better than 80% efficiency if you're running a system at 50% watt usage.

I really like this power supply because I only needed very few watts but bought this because it was my only option, and it's great because the power needed from my pc doesn't stress it work hard.

Nice and plenty of ports. And in stock. 850w modular has more connectors than competitors psu. Cable thicknesses are all high quality. Between this and Evga you can’t go wrong.

Purchased this as a replacement for my Coolmaster 750W. I love the ease of which this unit was to install and the modularity it provides for my system. It provides clean and consistent power at an affordable price.

Nothing sexy about a psu, has done its job so far! All the needed cables. Might need extensions if you’re trying to be totally aesthetically pleasing

Bought this due to seeing the RM750 in use in my kids build. Wanted a bit more power for mine and this is just as good as the RM 750. I'm probably never going to use a different brand again.

Runs my PC smoothly and was extremely easy to connect. Really worth the price that isn't that absurd either. Wattage may be high but if you plan to overclock don't hesitate on this.

This PSU is powering two GPUs (RX 6800 & RTX 3060 Ti), a Ryzen 7 3800x, three HDDs, one SSD, ATX mobo with 4 sticks of RAM and 4 fans and an NVMe SSD. This PSU is a beast.

Running Ryzen 5950x, RTX 3090, 32GB dominators, Corsair H150i Capellix as well as 5 other fans in my case. Never have had a power issue. Great performance.

Great modular power supply. Used this for my first computer build. I like that its modular so you only use the cables that you need, no extra unused cables left over to shove in the case.

I hope this works. If I could purchase the GPU I want or a close fascimile of said one maybe I could give a more in depth review of a this PS I have not been able to use, ugh!

This allows my PC to run one of the best graphics card there is, RTX2080! There is no problem on the power now.

Solid PSU. Searched many reviews before purchasing on other sites including just tech review sites. It has very stable power and quite a long warranty to back it up.

Extremely easy to install with very high grade cables. Runs very silent and maintains a very cold temperature even at extreme loads. Will recommend to any body building a PC

First of all it is pretty quiet and I really like the solid build while keeping a low profile and you get 10 years of warranty which means you can use it across several units.

Good quality, and aftermarket cables are available to keep your build super clean. It's inexpensive for a high quality fully modular power supply from a reputable brand.
