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.

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

So far so good. It's quiet, it's consistent. Everything I read about it. I highly recommend it.

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

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

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

easy to install, comes wirh a ton of cables. its not loud, what more do you want

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

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 a really great power supply. Straight forward to install and handles my GPU (7900XT) power needs with no issues even in a high gaming load scenario. The quiet fan feature is really nice when you are trying to quiet down a larger pc with several fans already running. Cables are nice a quality and with Corsair you have the option of upgrading to a specific color beyond the usual black. The warranty was a big factor I chose this power supply over others.

That's a lot of power in box! Works great and installs easily.

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.

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

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

Super easy install and the fan adjuster knob is a very nice feature! Well worth the money spent!

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

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.

Great power supply, easy to install and the modular setup is great for no excess wires

Been working great, no issues. Runs quiet. On LTT labs, this shows up as a solid choice.
