Awesome! This is quiet and provides ample power to my PC. I would recommend this Power Supply. I have had several Corsair Power Supplys and they have always been a solid purchase.

Bought 1000w for my new 5070 and was overly satisfied with this psu and this time kept all the cables

Great PSU! I had to replace my 2.53 version ATX unit due to power spikes causing my GPU to black out and stutter. This unit is amazing. Rock solid power

Works great. Never used knob though. found it quiet and default settings are working good. Also, very high quality cables.

Amazing power supply has been going strong in my main pc I had bought 3 of these in the past and none have gave me issues or died on me I will keep buying corsair until I run into any issues

This is a great power supply, lots of power and great price.

I bought this to future proof my PC, have had no problems with it and I am excited for when the time to upgrade my PC arrives.

Really helped to upgrade my coputer speed. The power supply upgrade gives me more room for future upgrades

Runs quite l, not as loud as I expected being so big, doesn’t add much noise if any. Easy install and plenty of ports.

Great for a Rtx 4090 build. Has dedicated 12HPV cable that will work with most modern Nvidia Graphics cards. Enough power for a full ATX powerful gaming build. There is a knob on the back that can help with saving power draw on less poer hungry rigs.

Needed a larger power supply for new video card. This was more than enough and works fantastically! Can be quiet if need be, but is unnecessary for me, so I opted for it to run at optimal efficiency for power delivery. Great PSU.

If you're in market for a PSU, make sure do a google search for "psu tier list". It's a google doc with ratings for pretty much any PSU you will come across, probably find it posted on reddit. Recommend first checking out any PSU against the list before picking one The RM1000x 3.1 atx 2024 version is rated A+ and a solid PSU to get. (750w and 850w from the same line are also rated A+) My only complaint is while I got every cable I needed and then some, the PSU cables are braided but don't include cable combs, so you need to purchase them separately if you care about keeping your cables super neat

Loaded up to my Pc and worked like a champ. Highly needed for better performance. 10/10

Works great. Showed up in good time and my pc is running smoothly

easy to install and had all runs great and future proof for my system

Very well made power supply couldn’t be happier and way more than enough power to run everything I have

The Corsair RM1000x is a top-tier power supply, offering a blend of performance, efficiency, and quiet operation. It's an ideal choice for high-end gaming or workstation builds that require reliable power delivery. With its fully modular design, solid efficiency rating, and extensive protection features, the RM1000x offers excellent value for those who need a powerful and long-lasting PSU.

Great quality, runs quiet, & has all the wattage I need to power my pc.

I’ve had mine for over two years already and no problems. Great power output.

Great PSU. Has all the connections you need and is quiet. you can change the sound noise which makes it great.
