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

So after my purchase, I went home and replaced my old 400w psu for my new 850w psu and it was very simple and easy to install, and I haven’t had any issues since, will come back after longer time with it to review again! GREAT PSU FOR ITS PRICE!

Work's great very quiet and very easy to install .

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!

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

replaced a 6yr old PSU and i love the new cables makes cable management a breeze.

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

Super Quiet. Great performance paired with my Intel ultra 7 and RTX 5070 ti. Cables are great and look very good. Easy to install

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.

It is everything it says it is. Quiet, fully modular and the cables are of superior flexibility.

I upgraded to this from a 650W PSU as I needed a bit more power for my 5070 Ti. I was worried it might be noisy, but I haven't heard a peep out of it since installing it. I'm not sure the fan has even come on once. It's pretty compact so there should be no issue fitting it in most builds. The cables are a nice change of pace. They're not quite braided, but they're not the usual rubber cables you see with other units. It's also nice they include a comb to keep them neat. Happy with my purchase!

Great power unit. Modular system makes it clean and the 12v high power cable plugs right into all of the modern GPUs. Fan is quiet!

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

My RM750 went out after like 8 years and I needed a little more power anyway so I went with the RM850x. It has plenty of ports for everything. It also has the newer upgraded cables which make install a little easier because the cables bend around corners better. So far, it works like a champ. Plenty of power for all of my gaming needs.

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

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.

[Employee of bestbuy] fully modular easy to set up and super quiet. works perfectly for any build.

Amazing power supply, easy to setup and is low noise

What can i say works like it should. Bought a pre built and i thought the power supply went bad. But this one has been working great. Easy to install and came with everything i needed.

It has been powering my new PC with no issues. More than enough power for my setup. Pricing wise, I think it's fair for what you're getting. Being fully modular is a plus for me.
