Customer Ratings & Reviews

Power supply is really quiet and extremely powerful. Native 12V-2X6 Connector ensures compatibility with 40 series NVIDIA GPU, and 50 series.

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.

I went from a 3080ti and ThermalTake 750W grad tough power RGB PSU which had served me well for about 8 years to a new 5080 GPU - Asus TUF version. I wanted to ensure stable power and also wanted the new PCIe connector for a simplified install. This bad boy did the trick!

This has been a great PSU - very good build quality. Easy installation and packaging.

Extremely satisfied with this power supply. The cables provided are very nice quality. The fan dial is very easy to use & future ready for newer graphics cards.

I always heard good things about CORSAIR's various power supplies and wanted to get one that would be adequate for future upgrades to my pc.

I was using an 850w PSU with a 4080FE and had power issues. All solved with the 1000x. Highly recommended for higher end gpu.

Great power supply does what it was built for high quality!

Awesome power supply, comes with nice cables and love the modular setup for it.

This was the best choice. It is performing beautifully. Very happy with it.

Decided to go with a 1000W instead of a 850W to have room for upgrades or OC with the Rtx 5080.

Hookup was easy works great with a 13 fan case and a 4080 super

It is worth noting is actually a PLATINUM efficiency rated PSU per the Cybernetics report and analysis ln their database, a step above the Gold Cybernetics rating printed on the box. Onto the PSU itself, it does its job well and with class. It is virtually silent at idle and under load, and my sample had no coil whine whatsoever. It powers my 7800X3D/4090 system exceptionally. I installed this after trying a brand new ROG Thor Platinum II 1200w, which not only was more expensive but had horrific coil whine out of the box both powered on and off along with a rattling fan. This PSU has no compromises, runs efficiently and quietly, and is priced very fairly. Get this one if its a top-tier 1000w PSU you need.

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 had an older power supply that was outdated because I upgraded the rest of my pc over the years. It wasn’t providing enough power to the pc which would cause it to shut off. This power supply works amazingly, is super quiet and fixed my issue instantly. I don’t have to worry about upgrading power supply any time soon bc this does the trick

Works great and was easy to install. Couple of connectors into the PSU where not so easy to seat but with a little change of angle eventually inserted with no problem; never had to force anything. Cables look premium, all black. And includes cables to connect old and new style GPU cards.

I paired the CORSAIR RMX Series RM1000x with my new MSI RTX 5080 GAMING TRIO OC, and this power supply hasn’t flinched once. If you're building a high-end system with next-gen components, this PSU has your back. Power Delivery & Efficiency: The 1000W output is more than enough to handle the power-hungry 5080, a Ryzen 9 CPU, and a full load of peripherals. With Cybenetics Gold certification, it’s delivering clean, stable power without breaking a sweat. Silent and Cool: Even under full load with the GPU and CPU working hard, the PSU stays whisper-quiet. The zero-RPM fan mode is great for low-load operation, and when the fan does kick in, it’s barely audible. Top-Tier Build Quality: The fully modular design made cable management super clean, especially with the 5080’s 12V-2x6 GPU cable, which is conveniently included in the box. It plugs right into the PSU without needing an adapter, keeping the setup tidy and efficient. All the included cables are high-quality, clearly labeled, and flexible enough to route cleanly even in tighter cases. Perfect Fit for Next-Gen Builds: If you're running a 5080 or planning for future upgrades, the RM1000x gives you plenty of headroom. No random reboots, no power hiccups—just solid performance from the ground up. Verdict: CORSAIR nailed it with the RM1000x. It’s efficient, quiet, and has no problem supporting high-end components like the RTX 5080. This is a premium PSU worth every penny.

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!

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.
