Customer Ratings & Reviews

Great power supply with a quiet fan! Lots of cables to power my PC for gaming! Atx12v cable for my gpu, also! I should be using this PSU for a long time!

This power supply is fantastic! Very smooth installation. Very quiet. I love the modular feature. So happy with this purchase!

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.

Works great. Had a Gigabyte power supply blow on my computer and replaced it with the same model for that one to blow within a few days of recieving. So I bought this Corsair to replace it and swapped all the cables, it qprked just as expected and still works. Also the optional manual fan control is a nice added feature. I will no longer buyGigabyte power supplies and will now continue to buy Corsair

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.

Excellent PSU. Upgraded from the old RMX1000 (20201) to this version and my coil whine is completely gone, RTX 4090, i7-12700K based system. Not saying this will fix it for you if you have this issue, but I am incredibly happy with it, as I tried swapping out a bunch of other components, including the GPU itself, motherboard, ssds, and it didn't fix the issue.

Not much to say, high quality single purpose piece of hardware. Powers my 7900xtx over locked beautifully. My previous 800watt couldn’t keep up with transient spikes, this solved the issue. It may be as powerful as a microwave, but it works well. Came with plenty of accessory cabling and I like the look of the individually textured cables.

Swapped a potentially problematic PSU for this one in a new build. The pin layout on the PSU itself is very neatly organized and easy to manage. It was a lot easier to install than the other PSU we were using. Very quiet, powers everything very nicely. Highly recommended.

Nice Modular Supply, Upgraded from a Corsair CX750m it was Semi Modular which made cable management a lil more of a pain. Another plus is the 12vhpwr cable making hook-up to 40 series a breeze & looks clean. Fan is quiet since it barely has to run but also being able to adjust is nice.

Solid PSU with the latest compliances and features for next-gen PC components

Silent PSU and was a decent upgrade from my 850w which was also Corsair branded. I may have gotten accidentally pricematched to a different PSU now that I'm looking at the design but I do not mind the upgrade.

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.

Its a safe choice when it comes to PSU's that can protect components in the case of damages or surges. I have seen 2 of these break and protect all components flawlessly when faced with this Island's surges. I can safely recommend it.

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 power supply module is perfect for my PC. After some years, my original power supply got fried, so I ordered this in its place and it is working like a charm. You can't go wrong with Corsair products. I am a review person, so of I see other consumers rate a product well, it must be a great product and that is the case for this power supply.

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 is a great purchase for your system. It powers my system with a 3090 rtx graphics card with no problems. It also has an adjustable fan speed on the power supply itself. Easy to install. Took about 15 minutes

My pc would just randomly shut off mid game/stream so I upgraded my power supply and since then I haven’t had any problems plus it was a great pickup for all my future upgrades!

Upgraded from a 20 series card to a 50 series card and needed a 12vhpwr cable, went with this corsair and so far so good, playing for long hours and the only warmth im feeling on the cable is from the fans blowing the hot air off the card on to it. Stable, and works great.

This Corsair RM1000x power supply is a really good product and works great, just like the title says. The build quality feels excellent, and it offers fantastic value for the price. Installation was straightforward thanks to the fully modular cables, which helped keep things tidy. It powers my system reliably without any issues so far. Definitely recommended if you need a high-wattage, quality PSU.
