RM1000e (2025) Fully Modular Low-Noise ATX Power Supply with 12V-2x6 Cable – ATX 3.1 & PCIe 5.1 Compliant, Cybenetics Gold Efficiency, 105°C-Rated Capacitors, Modern Standby Mode – Black

Been using Corsair for my PSU needs for years. None have let me down and this one is looking to continue that trend. Absolutely stable power delivery. Cables are high quality. Powering my 9800x3d and 5080 setup flawlessly since October 2025 now. Absolutely zero noise either from internals or the fan. Came with all cables I could possibly need. Cable length and flexibility are fantastic making them easy to manage.

I've used Corsair power supplies for years. Well recently I updated my PC and needed a bigger Power supply. So I bought one that WASN"T corsair because I thought that "Its just a Power Supply I'll be fine and cheap out on it" Turns out the one I bought, the PCIE cable was super weird and had way too many extra cables. The CPU cord just was not long enough, so I was not able to have nice looking cable management. And to top it all off my PC would boot up but instantly shut down. So instead of messing with it, I just bought this Power Supply. And it has all the correct cables you need, all the appropriate lengths. And I love that you can choose which cables you need and which ones you do not. It makes for a nice clean look for your PC. I hooked up all the appropriate cables, and it powered up and worked first try. So all in all lesson learned, I will be sticking for CORSAIR power supplies for the rest of my life!

Good psu. Not sure I have ever noticed any noise, though I do usually game with a headset anyway. Looks good, works perfectly, and fits in my matx case without charging me a sff tax. Lian li has 'em beat on cable combs, but other than that I an very happy with this PSU. This and Lian Li edge are probably my gold standard for ATX sized power supplies. Might be trouble if you need more power connectors though. One thing to watch for: I have upgraded the GPU since this pic was taken, and had I chosen a gpu with 3 of the 8 pin power connectors, I'd have been out of luck as my motherboard uses 2 olf the 8 pin connectors on its own, and the PSU only has 4 of them. There are models that have more 8 pin connectors, but this one exchanges them for one of those 12 v connectors that have been burning up GPU connectors. not a concern for everyone, just make sure this matches your other parts and needs.

Awesome power, very quiet,works great

The benchmark for solid power supplies - It's comforting to know when they say "1000W" they mean it, and it's steady and stable.

This has been the worst power supply I’ve used. It was defective since day one. I originally thought it might have been a faulty gpu and swapped it out for a 5070ti. Everything was working fine for a while but then the same issue happened again where my pc would try to start up but fail to boot up immediately. I switched to a much higher quality power supply from seasonic and my pc has been running great since then. I would honestly avoid getting this one or any power supply from Corsair. Don’t cheap out on a power supply because you’ll regret it later. The cables that come with this power supply also feel really cheap and could break easily if you’re not careful.

I upgraded my GPU recently to a GeForce 5070ti, so I decided to update the power supply as well. It's been running for a couple of months now, and I've had no issues. It's quiet, with no humming or buzzing, which I've had with others. I probably could have gotten by with my 850W, but I feel more comfortable knowing I've got a little juice left in the tank with this one.

Works fine but smells like glue. Every time the fan comes on Its like I just got dunked in paint thinner
