CORSAIR RM1000e (2025) ATX 3.1 PCIe 5.1 Ready 1000W Power Supply – Black

This Corsair power supply has got to be the best PSU I have ever worked with In terms of Bench Testing a PC. The Modular Design lets you only plug in what is needed to make the system work, which allows you to avoid unnecessary clutter of unused cables unlike traditional PSU's. if i apply the concept of this power supply to building a PC, the Cable Management will be much easier as you will have extra space to store excess cables and can retain the unused cables in your box outside of the case until needed. During bench testing of my new system which contains the following parts: - ASUS ROG Crosshair X670E Hero - AMD 7900X 170 W - Corsair Dominator Titanium DDR5 - Gigabyte Nvidia RTX 3060 12G - Crucial T700 2Tb Gen 5 PCIe M.2 - Micron 500 Gb Gen 4 PCIe M.2 - RM1000e PSU 1000 W I was able to boot, and bench test (Cinnebench 2024) my system and this Unit didn't spin the cooling fan up once for the first 5 minutes of the test. Once the fan kicked on it was so unbelievably quiet. My current system has an EVGA 650W power supply in it and that thing sounds like a leaf blower sometimes. The Corsair PSU functions in a "Zero RPM" state only spinning up when needed and the fan is so quiet you cant really tell when its on unless you are looking at it. I plan on Building y system once my case arrives, and will update my review about installation and cable management, and include a few pictures to boot. I Ordered Corsair Pro Sleeved cables for my build so I will not be using the stock cables in my final build, however I did use them for bench testing and I can say that the stock cables are nice, flat ribbon cables with a durable exterior coating. They are flexible yet sturdy, and can be easily Cable Managed with zip-ties and Velcro straps. Overall first impressions i would Definitely recommend this to people who need a great power supply with intuitive modular cable management for cases like the Corsair 4000.

This thing is a beast. the cables are top notch.. i had enough to connect my 7900XTX with 3x8-pin connectors. excessive amounts of SATA and and peripherals connectors.. you will never need that many but its nice to have them. unit is heavy and does an excellent job and heat dissipation. its quiet and outside remains cool. Corsair has kept an excellent quality standard over the years, where many competitors have fallen off... looking at you TT. couldnt be happier with this PSU. AMD Ryzen 5 7800x3d, MSI B650 Tomahawk, AMD 7900 XTX 24g, about 5 full size chassis and case fans, full ARGB internal lighting and rails, no issues with power or heat. solid PSU!

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.

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.

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.

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

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.

If you’re running a power-hungry graphics card and want plenty of headroom for future upgrades, this 1000W unit is excellent. It handles heavy gaming and streaming loads without breaking a sweat, and the fan stays dead silent most of the time. Being an ATX 3.1 / PCIe 5.1 ready unit is a massive bonus. It means it comes with the native 12V-2x6 cable, so you can plug it straight into modern high-end GPUs without dealing with those ugly, bulky multi-cable adapter dongles. The fully modular design means you only plug in the cables you actually need, keeping case clutter to a absolute minimum. Just keep in mind that the included stock cables are a bit stiff out of the box. Take a minute to pre-bend them gently before routing them through the back of your case, and you'll have a super clean, hassle-free installation.

Una belleza de fuente de poder, la compré para mi nuevo build de Ryzen 9900X3D y RTX 5070 TI . Super recomendable para evitar tener que utilizar el cable Y que viene con la tarjeta de video. Si ya invertiste en una GPU cara, mejor cuídala! La fuente viene con su entrada y cable de 12v 2x6 especial para la GPU.

Most people don't realize they need a good Power supply when they're building their PC, and it's the part that get the bottom of the budget sheet crushing a 60$ there... This one has a name, it's 1000w, ATX 3.0 ready... It is worth it to invest in a very good PSU now, so you can transfer it through multiple PCs in the future, making the right investment now even save you from having to list a PSU in the budget sheet of your next 3-4 future builds. Isn't this even better?

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
