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 – White

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.

Amazing power supply includes all cables i could possibly need for my build. the 12v Rail produces constant even power levels that my GPU truly enjoys. Having owned several corsair products in the past I am confident in the build quality of this unit and have yet to have any power issues at all, installation is simple and it did include the screws and zip ties for cable management. this power supply has wonderful performance and provides a great value for the price as one should expect from Corsair.

Bought this for my first PC build and it’s a great power supply for the money. It’s powerful and quiet. Cable management is simplified.

I used the PSU for my side server that I am constructing. I got it and was a bit jelly because of the wires that were shipped with it. The look of it was good, no bells and whistles, but still. On my main PC, I have a 1200W Asus Thor. The 1st Gen. I was tempted to switch that out with this product. In the end, I set up my server. Plenty of power for my Intel Core i9-10980XE matched with my Nvidia 3080. It is very quiet as well. For what I paid for it, I recommend it. No problems installing it. I mean, it's only 4 screws. Cable management was simple: use what you need. It even comes with zip ties. My Asus PSU never did.

It's great. These once came with a fabric bag. Those were the good old days.

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)

Fonte funcional e silenciosa. Atendeu às configurações do Pc que precisava de um PSU de 850w. Sempre usei Corsair e os produtos são de qualidade, a marca oferece 10 anos de garantia não é atoa.

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

Pros and Cons as well as the overall rating at the bottom This PSU delivers stable, efficient power with low noise output, making it a strong choice for systems running high‐end GPUs like the RTX 4080, 4090, and upcoming 5000‐series cards. Despite being marketed as an 80+ Gold unit, real‐world testing shows efficiency levels that often approach Platinum territory, which is impressive for its price class. The PSU's compact size makes installation easier in mid‐tower and full‐tower cases, and the fully modular cable system helps keep builds clean. The included flat ribbon cables are long enough for larger cases, though they can feel stiff during initial routing. Still, once installed, they contribute to a tidy, airflow‐friendly layout. Noise performance is one of the RM1000e's standout strengths. The 120 mm rifle‐bearing fan remains off during light workloads thanks to Zero RPM mode, keeping the system silent during browsing, media playback, and light gaming. Under heavier loads, noise levels stay controlled and rarely become distracting. Electrical performance is solid, with stable voltage regulation and low ripple across all rails. Thermal behavior is also well‐managed, even during extended stress tests. The native 12V‐2×6 connector ensures full compatibility with modern GPUs without adapters, which is a major plus for long‐term reliability. The RM1000e a great value when discounted, but less compelling when priced close to its RMx sibling. Overall, the RM1000e (2025) is a quiet, efficient, modern PSU that fits well in high‐end builds and offers excellent real‐world performance for the money. Pros .Fully modular design with clean cable management .Very quiet operation with Zero RPM mode .ATX 3.1 + native 12V‐2×6 connector for modern GPUs .Compact size fits easily in most cases .Efficiency often near Platinum levels Cons .Flat cables can be stiff .RM1000x offers slightly better components for a small price difference .Slightly weaker performance than the RM1000x series Overall rating A+

Worked like a charm. Bit on the pricey side, but you get what you pay for here.
