Customer Ratings & Reviews

Got this unit for a new PC build. I have used Corsair products before and never had any issues. This new power supply is great as it is totally modular and you can use only the cables that you need leading to a cleaner look and easier cable management. Would definitely buy again.

Easy to setup. Nice modular PSU & nicely labled cables. Wish there was a manual to explain what is what and where is for why.

Great value power supply. Has been working very well for me. No coil whine or anything.

The included cables are a cleaner design than older versions. The adjustable fan option is fine if you're worried about wear on the bearings with starting and stopping. Well tested and reviewed unit.

Great product No noise Working fine so far I would strongly recommend it

Plenty of power for all but the highest end graphics cards. Good modularity for easy installation

Overclocking a modern high end build has posed no issues for this PSU, and it runs very efficiently and silently.

Works good so far. No issues. Like the make of the cables.

This works great and the modular is a huge improvement from my original PSU.

Good psu no complaints would reccomend. It has a fan speed knob which is cool

Very quiet and reliable power delivery for my components, and easy to organize with the cords marked

Really good power supply with more than enough power to run my 5070 and ryzen 9 5950x. Runs quite and couldnt ask for more out of a quality power supply

zero fan mode is awesome. Has all the power cables I could ever need and then some. Nice to see they finally left the rubber coated wires in the past and started offering some cable combs as well.

Functioning perfectly, and quiet. First time using a component based PSU and love the flexibility and cable reduction in my case. Would definitely buy again.

I upgraded most of my PC components about a year and a half ago (Motherboard, Processor, Graphics Card, Memory, PC Case) but reused my old 750 power supply which wasn't fully modular. I decided to get this 850 fully modular power supply for the added flexibility and to have some extra power for my components and it has worked flawlessly so far. Great product!

I Haven't put this power supply to the longevity test yet. However, I have loaded it up quite well at this point. It seems to be great so far. It has an adjustable fan and modular cable design is great. It should have all of the cables you may need.

solid power supply reliable as you can get and comes with good quality cables.

Great power supply. More than enough power for my custom build. Corsair makes quality products. Performs great.

Works great needed to replace my old one it was easy to install

What a beast of a PSU! I loved this thing and it is more than enough for my build. It is also really easy to install!
