Customer Ratings & Reviews

Quiet, Powerful, and modular power supply to keep your gaming rig humming for years to come. Supports RTX 50 graphics cards with the power they need for peak performance. It drives my Gigabyte Z790 with i5-14, DDR5, and RTX 5070 Ti.

works as advertised no issues with setup. Quiet fan all necessary cables work perfectly.

All-around great power supply, to the point that I would have been happy paying the regular price at the time. The cables feel and look great, and 1000W gives me plenty of headroom for any CPU/GPU upgrades down the line. 10 years manufacturer's warranty is also great for peace of mind.

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

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.

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

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.

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

looks great! I would recommend the corsair brand, ive talked to many about these they work well!

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

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

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 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.

Easy to install fan, works well and have had no issues using it

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

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

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

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

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.
