Customer Ratings & Reviews

Needed a larger power supply for new video card. This was more than enough and works fantastically! Can be quiet if need be, but is unnecessary for me, so I opted for it to run at optimal efficiency for power delivery. Great PSU.

Great power supply! This is the second one I've bought great power output. Love that it has the adjustable fan speed for it and how quite it is.

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.

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

Great and quiet PSU with an adjustable fan speed nob to make it easy to control, works great.

Great quality, runs quiet, & has all the wattage I need to power my pc.

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.

This is genuinely the best power supply ive got. Its got REALLY high quality, and a really high amount of wattage. Although overkill for most systems, id really recommend it!

Silent, clean, and well performing. The included cables are great quality and easy to manage

This PSU works great. Super easy to install, has plenty of power and connections. Using this to drive a 9800x3d and rtx 5080

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.

Plenty of power super quiet low fan noise cool temps also

Good psu. Run very quiet. Smooth performance! Definitely recommend!

Super quite and the modularity keeps the case clean. Highly recommend, powers my 5080 no problem

Its working pretty great. Its built well and has a great design. Powers my rtx 3080 ti amazingly

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

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

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

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