Customer Ratings & Reviews

This PSU is overkill for my PC build but it works great. It’s fully modular so you use the cables you need and it’s less clutter in your PC case. Having 1000w is more than I need but it just gives me room to expand and not worry about power.

Great PSU. Was mid build when the MSI one i had biught turned out to be faulty. I would have bought this but they were out of stock the week prior. Returned the MSI immesidately and picked this up and solved all my issues. Had used the previous model of this PSU in my build a couple of years prior. Works great and runs quiet.

Easy install. Adjustable fan speed is great for noise control. Make sure you use cables that come with supply for best performance.

Excellent power supply. Installation was easy thanks to the fully modular cables, and cable quality feels premium. The unit runs incredibly quiet even under heavy gaming and productivity loads, and power delivery has been rock solid. The 1000W capacity gives plenty of headroom for high-end GPUs and future upgrades, and the overall build quality feels top-tier. No coil whine, no instability, and great efficiency. Exactly what you want in a PSU — reliable, silent, and well-built. Highly recommend this for anyone running a powerful system or planning future upgrades.

Does exactly what you need it to, no qualms here... Having control of the fan speed is pretty nice, it rarely ever needs to be turned up so its dead quiet

Honestly hasn't caused any problems for me. Fully powers my AMD RADEON RX 9070XT, which for me it's plenty. Since the 9070XT consumes 300-330w but has a recommended 850w PSU(Power Supply) this has plenty of room for anyone that might want to further tweak it. All in all, this Corsair Power Supply has been a blast to have. I'm satisfied with it being powerful and reliable. P.S. this is based on me. Personal review. But I recommend it.

Works well. I like how you can change the fan speed manually and that is modular

Bumped up to a 1000 watt to go with my 5080. Steady silent unless you turn up the fan. Manual fan control knob. No issues.

Easy to install, ample cables, quiet. This solved an underpowered graphics card problem.

The CORSAIR RM1000x has been a great choice for my gaming PC build. It feels very well made, runs quietly, and the fully modular design makes cable management much easier. 1000W gives me plenty of headroom for powerful components and future upgrades. Installation was straightforward, and I definitely recommend it for anyone putting together a high-end PC.

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.

Highly recommend easy to install and the optional fan control is very nice when running intensive loads

A lot of these mid - high tier PSUs are pretty comparable. What sets this one apart is the flexible cables. The plastic stiff cables on other PSUs are not the easiest to work with / are kind of ugly. This is solid. The dial on the back to control fan speed is pretty cool too. Fans get loud if you turn them on, but I have the dial turned off while my PC is under load, and it doesn't get hot or loud. Solid PSU

Powerful and quiet! So far it has ran my ASUS X870E-E, 9800X3D, and 5070ti with zero issues! Highly recommended.

Bought this to replace a failing PSU and does what it says on the tin. It's definitely quiet and the build quality and materials feel premium. It uses individual stranded cables rather than bundled which makes it easier to work with (if a bit more involved to manage cleanly). The only downside is that I needed 2 4+4 runs for my CPU, 3 6+2 PCIe runs for my GPU, and two 6+2 PCIe runs for my iCUE link system (I run two nodes) and so I was one short. Thankfully I was able to rearrange my setup to only need one node, but if you need more than 6 CPU/PCIe runs you're gonna have a bad time.

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.

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

Works great for what I need it to do. It's quiet. I have not been able to hear any increase in noise since installing.

Works perfectly. Plug and play. Eliminates a significant amount of extra not needed wiring

I impulsively bought this PSU after realizing my RTX 5080 for my new build needed the latest ATX power compliance. It's quiet, does it's job, and is well-tested and regarded as a quality PSU that goes beyond its standards. If you need a PSU that gets the job done, and don't want to shop around - this is it.
