Customer Ratings & Reviews

The CORSAIR RMe Series RM850e has been an absolute powerhouse in my build. Installation was incredibly easy thanks to the fully modular design—I only had to plug in the cables I needed, which made cable management super clean and kept the inside of my case looking organized. Performance-wise, this PSU delivers flawless, stable power. With the 80 PLUS Gold efficiency, my system runs cooler and more efficiently, and I’ve noticed zero coil whine or electrical noise. Speaking of noise—this thing is practically silent. Even under heavy gaming or rendering loads, the fan barely kicks in, and when it does, it’s whisper-quiet. What really sold me is how future-proof it is. With ATX 3.1 and PCIe 5.1 compatibility, it’s ready for the latest and upcoming GPUs without needing any adapters. It gives serious peace of mind knowing my system is set for future upgrades. The white finish is a huge bonus—clean, premium, and perfect for white or themed builds. Overall, the RM850e is powerful, quiet, efficient, and built to last. If you want reliability and modern standards in a sleek package, this power supply is a fantastic choice. Highly recommended!

Great PSU overall. I am happy with this. It was a good price around $130 and is a good wattage for my demands. It is fully modular and comes with all of the connectors you need to use on any part of the MOBO or GPU. Corsair makes great and reliable products. White color is very nice as well and looks good in my white case. I would recommend this product for anyone looking for a solid PSU

Plenty of cables to get the job done plus it’s modular so no extra cables to hide, near silent operation when fan is running and completely silent when fan is not. Fans will not run under low load/temp in turn this means less wear on fan bearings, less dust, and longer life. 10+ years of pc building and gaming experience has proved Corsair is a leading manufacturer for a reason, their parts just seem to last and work well given they are installed properly and used within the correct thresholds.

Great product, runs very well, doesn’t get very hot, it’s very quiet and overall just a awesome power supply, I used in my high end gaming pc and I’ve had no problems!

Super easy install, upgraded from my 600 watt power supply that was almost 10 years old. Love that this unit is modular so you can omit cables that you don’t need.

Worked very well for my setup and now it doesn’t turn off randomly very easy to wire recommend for beginners I did it all myself with 0 prior experience

Needed a PSU with plenty of power for any GPU I want to throw at it. New OEM cables are nice and clean. Good warranty.

Plenty of power for intensive gaming I love it and it works great with my am5 upgrade

Wow, I was impressed with this coming from an older 2021 seasonic GX850. First of all the cables are of a much nicer and more flexible quality, you can feel the difference instantly. Secondly The adapter for newer Nvidia GPUs was so nice, I don't have to use the adapter and have extra cables now as they already come with the Nvidia 16pin to 8 pin x2 extension. Also the white is perfect with my white Antec Flux Pro Case. This is also Gold certified, makes almost no noise and is fully modular. Corsair has won me over and this isnt my first PSU from them. I've had an HX750 way back in the day and it was reliable until I needed more power.

So much power I can hardly handle it! I'd plug this into my brain if I could!

Dedicated 12VHPWR slot and cord, Modular, WHITE CORDS, quiet, cybernetic gold what else is there to say? Amazing value for an 850W psu. Also on tier a - high end on the psu tier list if you know or follow ZTT on youtube!

I love this modular power supply. Its minimalist style and its capacity to allow an specific amount of wires, makes it the best option I could find

Very solid power supply!!! No complaints so far, using alongside a UPS. Fits well in the new 4000D series Corsair case even though its not the “shift” version

Easy to install and I love the modular cable design. I am able to omit the cables I don't need to install.

PSU upgrade was essentially needed. Works great and was a solid buy

Great products for the cost runs very quiet have had no issues and I’m running local AI so pulls a lot of power at the same time. Comes with enough wires to run two GPU’s as well.

this is great the cable are white if your setup is white theme is a A+ so you not need a cable extention and so far no problem. i build a ryzen 7 78003d and rx 9070xt

honestly works perfect, I set it up in my pc and it runs smooth like butter.

Works great, no noise, upgraded to get the 12v connector for my 5070. Corsair quality

It works and has all the cables you need for ur pc
