Customer Ratings & Reviews

Very nice modular power supply. Contained all the cable connections needed to set up a new system and power to run all the devices - with a lot left over. Quiet, good power, decent price and available for immediate pickup. I recommend.

It works great and is super easy to set up! I was able to get this integrated with my pc in about an hour.

Works will with my RX 7700xt and Ryzen 5 5600. Quiet and reliable.

Great power supply works like a charm and never fails

So....These models aren't manufactured by Seasonic anymore but instead by Great Wall which is a pretty big OEM in the PSU market. They're good quality, They're not Seasonic or Super flower but Great Wall and even Channel Well Technology are both respectable OEMS. You can absolutely trust these RM Units. They use Japanese caps, The build quality inside and out is phenomenal. A lot of pride gets out into the building of these supplies. Can't go wrong with them for your next build. It's also nice to see the Cybernetics rating sticker, We're all used to the 80+ certification....and 80+ gold is great but cybernetics takes things further and actually test things like noise levels, Efficiency levels and I believe it even test Ripple and Voltage whereas 80+ does not. You're getting a good unit.

Went in to Best Buy unsure of my problem with my PC. The Geek Squad guys sat me down and went through every possible solution. Eventually we discovered it was the PSU. Since having my 600w PSU replaced with this 850w I haven’t had the emergency shut off problem while gaming! I’m beyond pleased with not only the product, but the amount of care I received when trusting my repair in Best Buy.

The CORSAIR RMe Series RM850e is a fantastic power supply for anyone looking for a reliable, efficient, and quiet PSU for their build. With 80 PLUS Gold efficiency, it delivers excellent power stability while keeping energy waste to a minimum.

Grate psu easy installation with sufficient power for all my components

I got this in preparation for a GPU upgrade and it's been working great. I was originally considering the RMx version of this, which uses a larger fan and Japanese capacitors instead of Taiwanese in the RMe, but it wasn't available at the time. I've been perfectly happy with the RMe version though. The modular cables are easy to work with and manage and I don't notice any noise when it's running, at least compared to my previous 750W PSU. Also, because the Best Buy listing is not clear, mine DID come with a 12V-2x6 cable for my Nvidia 4070 Super.

Love the easy of setting up. No excess plug ins. Use the slots needed.

Very happy with the quality and ease of use/ install with this power supply

Good product easy to use and install. Fully modular but could use a couple more cables

Good sized PSU wattage and physical size for my case and needs. Corsair always has been good to me in the past. I used the stock cables it came with and they look great in my case and are modular so they are easy to use around tight maneuvers.

This is the second Corsair RM850e I have purchased. Very quiet and small, not ITX small but small. If you are building a new system in a newer MATX case (Jonsbo, Lian Li A3, Asus Ap-201) you might look into this. It is only 140mm long. HIghly Recommend.

It is worth the price point, very sturdy, reliable and is good looking. 850 watts while also fully modular is a Worthy upgrade from my original 650 watt power supply for a nice price.

Works well had zero issues. Even after a power outage

Replaced my 8 year old power supply with this one. Modular xables were easy to work with. Power supply is giving the expected power output, no issues so far.

Perfect for my build, never once felt under powered. Literally only had to attach the cables necessary and cleaned up my wire management so much

Built my first pc and my friend recommended this power supply unit to me. It works well and very good for mid to high end pc builds.

Needed a higher and stronger PSU, Corsair never fails my expectations, an amazing PSU for the price
