Solid Power Supply
Solid PSU. It has worked great for the past year and a half. I have experienced no Power Supply issues in my build. It should fit any ATX case. The modular function makes it simple to use. Use the cables you need, and don’t use the cables you don’t need.

Great Power Supply; Well Engineered; Very Quiet
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.

Rock solid, works perfect
It's a power supply. If it provides completely stable power, is quiet, and you don't have to think about it after installing it, it's great. This one is completely stable, is quiet, and easy to install. Including 12vhpwr in the box was a nice touch, and it's a lot nicer to work with than the Nvidia dongle that comes with the 4k series GPU's. Not much else to say about a power supply. No real cons to this one other than it's a little stinky out of the box and for the first couple of days you use it. I assume it's the powdercoat they painted it with rather than the scent of raw power, but it lasted a day or two in a high airflow case. Captain Stinky here has been rock solid since I first booted up the system I powered it with, though, so it's not much of a complaint.

Works very well. silent operation. Corsair is quality.
You already know the name is quality. Corsair has earned its reputation of being quality equipment by making good, durable products. This PSU is easy to install and worked great. The included cables are all matching and look good inside my case. Modular design is a must have for me at this point. Cables are long enough to allow for hiding. Great PSU. Can't hear it run.

Perfect for my AMD 7800x3d and 7900xtx build.
Its a corsair product, they got a rock solid reputation for not producing crap. noise? what noise? out of everything in my case this PSU is not even noticeable sound wise.

A decent psu
I have bought this psu to replace a failing 6 year old corsair rmx850watt psu. The psu works great and i have used it for a little while now. Very happy with my purchase.

Great quality
I picked up the Corsair RM1000e (2023) for my build, and it’s been rock‑solid so far. The fully modular design makes cable management a breeze, and I really appreciate that it’s ATX 3.1 and PCIe 5.1 compliant, so it’s future‑proof for next‑gen GPUs. It runs quietly even under heavy load, and the 80+ Gold efficiency rating gives me peace of mind about power stability. The only downside is that it’s a bit overkill if you don’t need 1000W, but for high‑end rigs it feels like a reliable investment.

Why hide cables when you can remove them!
This fully modular PSU is great for the cable management aficionado. If you want control over what is actually plugged in so you don't have to worry about what trying to stuff extra cables into the cracks this is the PSY for you. It fit great in my Mid case with a standard size for a PSU. As is the case with all Corsair products you know it is a durable long term solution to your computers power needs.

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?

Aunque no fue el modelo exacto que compré , ya que pedi uno de 1200 whatts y me mandaron este de 1000 whatts..., la fuente en sí es muy buena y, sobre todo, silenciosa. Llevo más de un año con ella, cero problemas y sin rastro de coil whine. Corsair, en fuentes de poder, nunca decepciona, y la 1000E es un PSU excelente. Lo único malo es que no incluye conectores nativos para las tarjetas gráficas más recientes, por lo que tendrás que usar adaptador, que afortunadamente trae incluido, aunque las graficas nuevas tambien los trae, pero bueno. Si buscas calidad, fiabilidad y silencio, esto es una gran opción, especialmente porque usa capacitadores japoneses!

Excelente fuente, llegó totalmente sellada y sin ningún problema, solo un pequeño golpe en la caja, pero nada que afecte el producto, llegó con todos sus cables correspondientes y todo en buen estado por dentro. No tengo quejas de ningún tipo, cuando la compré tenía descuento y pensé que sería reacondicionada, pero no, llegó totalmente nueva y sellada, recomendadisima.

Since I changed my 2080 video card to a 4080 I needed to upgrade my Corsair 850W to at least 1000W. With this powersupply its energy efficient, quiet and a great price.
