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.

I purchased this PSU to replace an 850 watt version of the same product because I needed some additional overhead after upgrading my CPU. The previous one ran perfectly for 4 years and I have no reason to believe this one won’t do the same.

As a minor improvement, some details could be refined, such as small design adjustments, additional features, or increased durability in certain areas. These do not affect functionality but could enhance the overall experience.

easy install and enough just enough type 4 cable slots. adjustable wire holders make hiding the +2 pins easy

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.

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

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.

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

Product did exactly what I needed for my power intensive computer, modular ability is very convenient.

Plenty of power super quiet low fan noise cool temps also

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.

Its good. Power connector for the new RTX 5000 series is nice to have. One con is that the cables wires are not braided or connected within each module. So it can be messy without Velcro ties, etc.

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.

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

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.

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.

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

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

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

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.
