I upgraded to this PSU after experiencing some major coil whine with my older power supply. This thing is quiet and eliminated all of coil whine in my system.

Awesome product. Well over what I needed but gets the job done for a good price and when I upgrade more internals this will still be able to handle it!

Handles all most up to date components with no problem. It comes with a feature that the fan won't spin if the case is cold enough, so that the PSU can have more space to handle everything without using energy on itself. Cables aren't that flexible.

Great product! Quality, definitely a cheap, reliable, and affordable spu!

Solid exactly what I needed to finish my build. I wanted to use cable mod cables and they were easy to find that fit this model l.

Great PS at a great price. It does what it should and is easy to install.

This replaced a 750 watt power supply from my Cyber Power gaming computer and installed by the Geek Squad. What an improvement. I cannot hear anything running....extremely silent,.

Great at doing what its meant to do. Have had corsair psu in the past and have always worked great for me. Always should get a modular or semi-modular PSU.

Great upgrade for my original set up, of 600w bronze. 5700xt to 7900xt huge upgrade

A great power supply upgrade after my last one took a crap on me. Corsair makes tons of excellent products and this is certainly one of them.

Good power supply that does what's needed. Check what your motherboard and components require before purchasing this power supply though, as there are multiple versions of the same RMX depending on the year. You can still get the older versions in Best Buy (or elsewhere), and you could potentially need more cables of a particular type in certain builds that come with a specific year's version of the power supply, which could be a bit annoying when shopping too.

After a power surge, my computers battery fried and I needed to replace it. So far this psu has given me no problems, and for people deciding between modular or non modular, I would recommend going modular; it lets you use what is necessary, and you don't have to leave the spare wires within your computer like you would with a non modular. It had also let me understand more about my computer since I am fairly new to all of it

Powering 6 RGB fans, 3080ti overclocked, i9-12700, two SSD, one HDD, and more. Solid performance. The fully modular system was great. Does NOT come with enough 8 pin connectors (not daisy changed) for a 3080ti.

Really happy with this Power supply no problems. Have almost all Corsair components none have ever failed me.

Upgraded my computer and I have been very pleased the the performance of this power supply. Best thing I can say is I never worry about turning on my computer.

Work great on my PC! Just replaced my old Corsair power supply from 2015. These things last for a long time!

This is a good power supply and it was fairly easy to install only took about 30 minutes and my pc was up and running

Good product to support your 3080. Could go a little higher than 850, but is enough.

Excellent product by Corsair yet again. 850 watts is perfect for my build and the modular cables are a fantastic perk.

After upgrading my power supply my pc has never been better after getting a this jumped from a 650 to 800
