Customer Ratings & Reviews

Great build and cable quality. Fan control knob is also great for fine-tuning noise level. I uprgraded from an Apevia PSU, it is nice to know that this Corsair has good reliability and I wont have to worry about replacing it for years to come.

This power supply works great it has a fan control on the back where you can manually set the fan speed but I’ve only had it for a month

Its a nice power supply; I haven't had any issues with power draw, no funny smells, stuff like that. The unit rattles/vibrates irritably and VERY loudly at a certain fan speed when set manually, but it's got an "auto" function that controls the fan speed if you choose. When on auto, I haven't noticed the rattle, and I don't believe the fan kicks on audibly. I like that the cables are flexible and seem to be nice quality. It allows for much easier cable management and a nice looking setup.

Doesn’t make any whining noise, enough to power my 5080 and 9800x3d, amazing product

Have no complaints. Been using Corsair power supplies for over 10 years and have had no issues with them. PSU is quiet and have had no issues powering a 5090 and a 9800X3D

Upgraded to a new graphics card and i had the older rm850x series. I bought the newer model that had the newer 16pin 12vhpwr built into the power supply so i didnt have to use an adapter. Thought i might as well upgrade to a high wattage too. So far, works just as advertised.

I needed new power supply for my pc and this one was a good price for the wattage and it fits inside my case. It's got plenty of power and wattage to support anything and runs really quite, and it was easy to install and came with all the cables needed to hook everything back up. I would recommend this particular unit to anyone and the also the brand as well. It's quality is really good and run any pc for years to come

I've used Corsair power supplies in every build for the last 10 yrs. They've never let me down. The modular construction means you only use what you need, lessening the clutter of your case. If you want the best power money can buy then Corsair RM100x is for you.

Powers my build. It has no issues and its really quiet. Corsair products are reliable from my experience and it has a 10 year warranty from Corsair so that eases my mind although I hope ill never have to use it.

The RM1000x delivers reliable power with great efficiency. Installation was easy, and the fully modular design helps with clean cable management. Highly recommended for high-performance builds.

The CORSAIR RM1000x is a great product. It's very quiet and is working exactly as advertised. 10/10 reccomend!

I’ve been using Corsair products and power supplies for years. They are very reliable and this one will likely last quite a while as well. In the event that it doesn’t, Corsair has a 10 year warranty and an excellent RMA process so you can feel safe with your purchase should any issues arise (which isn’t likely given their track record). I paired this with a 9950X3D, Corsair Titan 360 iCUE Link , 96GB DDR5 6000 CL 30, and an RTX 5070, and it handles it no problem.

It works pretty well. The fan is unnoticeable, and also, if there's a Cybernetics platinum version of this PSU, because the box says Cybernetics platinum

I was very satisfied with this item. It's plenty enough power for my pc. Very good quality build love the adjustable fan speed.

Very quiet, runs cool, performs as expected. Runs my system and my 5080 well.

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

The new cables are nicer to work with and the Included cable for more power hungry cards takes way less space!

great product, I had to upgrade my system due to my power supply not being powerful enough and this works great.

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.

WE replaced our old one that we had on our home sound system and it has worked without any issues. We have it so it puts the system to sleep. It is hooked up to the sound system and our theater system downstairs. FYI just don't buy the least expensive buy quality that will last!!!!
