Customer Ratings & Reviews

After 2 years Product started having issues. Not too happy.

Nice Power Supply. I bought this for my son's new rig and I'll be buying one for mine soon too. Plenty of power and runs quiet and cool. if you're in the market it's a great PS to purchase.

This is a nice quiet power supply. After benchmarking it with some load, the performance is stable. Powering a Rizen 5600x with an RTX3070 and 3 SSD drives in a Corsair 280X case.

Good quality ! I just purchase the unit and would update once I had it for some time. This feet’s perfectly the 4000d airflow from Corsair O Olán to get the new amd chipset and a 3080 when I can

Works excellently, only downside is that the PCIe cables for the GPU are split into two 8-pin power connectors. This makes it seem like you are supposed to daisy chain the GPU, instead you should use two separate 8-pin PCIe power connectors for the GPU, it is also really hard to hide the second set of connectors on the cables affecting the appearance inside your case.

Fully modular Excellent gold rating efficiency Large protective encasing 2018 redesign with quiet fans Ready for X570 and RTX 3080 and Big Navi Price is right as most competitors with cost $40 more

I purchased this power supply for a new computer that I built and it provides all the power I need. It's running a high end AMD graphics card and high end Intel processor.

One word: solid. Powers everything with room to add more things to it. Powers a computer with 8 RGB fans, a decent motherboard, and a 5600x at the helm without issue. Made my PC build easy.

This is an amazing power supply. I would recommend this version of the RM 850x because it comes with more cables than the newer version and the cable quality feels higher.

Great price for the quality! Smooth and quiet operation. I was surprised when I turned on the PC that you couldn’t hear anything! All I hear it the spinning of my fans!!!! Great job Corsair!

You can’t go wrong with Corsair. From all the other options out there for a power supply, I always find myself circling back around to Corsair. You can feel confident that your getting your money’s worth with this power supply.

Got this to replace my old PSU. Easy to install and fully modular!!! The cables are a little short for my liking but all cables work and it gets the job done. Worth it! I recommend!!

Best power supply. So many options with the wires it comes with. Don’t have to have so much unnecessary stuff plugged and in the way in the case. And it’ssuper strong.

Replaced my existing 450watt psu in my gaming PC. So far so good! Runs cool & quiet. Currently powers my 3070, enough power for any upgrade. Would recommend to my pc building friends.

Love corsair psus, every other name brand ive come across ive gotten one brand new out of box that was broke. Corsair never lets me down, great power supply.

Corsair offers good products especially power supplies such as the RMx series. From previous experience, these are great especially for those who want to run an RTX 3000 series or above.

Always been a fan of Corsair and this power supply is no different. 850w and gold certified$145 is solid if you ask me. Having fully modular cables is a plus as well. No complaints whatsoever.

I went overkill on my power supply to get a 80+ Gold rating and a modular unit. So with that being said I love how simple this was to use and it’s great not having to worry about hiding unused cables

Easily installed into older Dell XPS 8700, a bit tight, but worked out well. I like the modular units better, you only need to connect what you need, so no extra cables laying in case. More than enough cables supplied.

So far so good an absolute beast of a power supply for my new pc build It’s currently running in a 4000d with a 3070 and Ryzen 7 5800x! It’s been running for more than 2 weeks now
