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 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!

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.

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

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.

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!

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

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

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

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.

Pretty good, no complaints for my 5070ti 16ti. I think moving forward more power (1000w) would do me better for 3D Rendering, digital and playing games. The case that I have is Nz xt h9 flow with dual monitor setup. From time to time, it it kind of resets my screens for 5sec i don't know if that's the psu or pc being that this is my first computer build. As of now, it does what it's supposed to do!

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

Corsair is a good brand , very good price. Can’t go wrong

My pc runs better then ever great price too. :)

Love how it was packaged made it vary easy to understand what was what.

Excellent power supply! The CORSAIR RM850e delivers stable, efficient performance with whisper-quiet operation. Fully modular design makes cable management a breeze, and the build quality feels premium. Perfect for high-end builds, highly recommended.

Love the color, it’s quite and the cables are good plus it hasn’t exploded yet so it’s 100% better then a gigabyte supply

Works as intended, very quiet. Haven't had any issues yet. The modularity is nice.

I’ve purchased multiple variations of this product over time, and the experience has been consistently excellent. Build quality is solid, performance is reliable, and it does exactly what it’s supposed to do without surprises. Installation is straightforward, fit and finish are clean, and it performs well under sustained use. What ultimately keeps me buying this is consistency. Across different models and configurations, the quality has remained dependable, which matters more than flashy features. When I need something I can trust, this is the brand I reach for, and it hasn’t let me down yet. I wouldn’t hesitate to purchase this again, and I routinely recommend it to others who want reliable hardware without headaches.

The CORSAIR RM850e PSU is a fantastic choice for any high-end build, especially those focusing on white aesthetics. Its 80 PLUS Gold rating ensures superb efficiency, while the fully modular design keeps cable management clean. Crucially, it supports ATX 3.1 and PCIe 5.1, providing essential future-proofing for next-gen GPUs. The low-noise fan makes it virtually silent under normal load.
