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.

Absolutely Shocked with the quality of this PSU. I've been a longtime customer of Corsair PSUS, i recommend it to all friends who are building their own systems. On my other retired PC rigs I've built are all loaded with Corsair PSUS ranging 500-850w. For my other build I bought this pup on sale and loaded it into my rig. Standard setup nothing too crazy its got a RTX 3060 it's whatever. The rig was purring like a kitten for a few weeks no problems everything running fine. I put my system to sleep to run out to the store and take care of some adult business. I come back and wake up my system and I get "Chinese firecrackered" on. I was shocked and could not freaking believe that the old "Chinese firecracker" cheap psu meme from back in the day happened to my Corsair. Thankfully none of my components were affected by the firecracker. I ended up putting back my 7 year old Corsair 850W HX PSU and the rig has been running just fine. Yeah I'm super disappointed. Moving forward my next builds will NOT HAVE CORSAIR PSUS. BUYER BEWARE. (Coming from a guy who's been a CORSAIR customer since 2013, I bought all their stuff)

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.

I'm dropping a point off this because the cables have 1 cheap, plastic comb. Are you serious, Corsair? 1 comb? I'd be less annoyed if it had no combs. Either put 3 combs on each cable, which can't cost you more than 2 cents each, or don't bother. Great PSU but I just spent the last 2 hours trying to get these bent to heck cables with 1 comb to look halfway decent. So annoyed right now. My back hurts.

Atendeu todas as espectativas. O que aconteceu de ruim foi que entrou em promoção no dia seguinte, fiz uma nova compra e não consegui cancelar a do dia anterior, mesmo com menos de 12 horas de diferença. As duas entregas vieram e rejeitei a que estava fora de promoção, para que eu pudesse seguir somente com a de valor promocional. No geral, essa fonte é uma nave, e desde então, não tive mais problemas com o PC reiniciando.

Esta bien, trae calidad y buenos componentes ya van 3 meses de prueba y ha funcionado perfecto

parfait pour mon setup viens avec tout les cables requis tres fiable j 'en avais un 850e sur mon ancien pc

Fonte muito boa e cabos muito bonitos! Está super tranquilo no meu sistema com uma rtx 5080, recomendo!

I have a Plex server with tons of internal and external drives attached. AMD 5900X with an RTX 3090. I was using a cheap Rosewill 1000W PSU. It worked for about a year until I started having issues. My CPU would get overloaded, drives were disconnecting and the PC would randomly shut off at night. All of this went away as soon as I replaced my Rosewill PSU with this Corsair. I love everything about this unit. The cables are braided and very easy to cable manage. It's also modular so you only plug in what you need. I will never buy another cheap PSU, I have learned my lesson. You get what you pay for.
