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

The CORSAIR RM850e (2025) is a solid choice for a modern gaming or performance PC build. With 850 watts of power and support for the latest ATX 3.1 and PCIe 5.1 standards, it provides plenty of headroom for powerful components while keeping the setup ready for newer hardware. I really like the fully modular design because you only need to connect the cables your system actually uses. This makes cable management much cleaner and helps improve airflow inside the case, which is especially nice when building a PC with a tempered glass panel. The included 12V-2x6 cable is another useful feature for compatible modern graphics cards, eliminating the need for bulky adapter setups. The low-noise operation is also appreciated, particularly for gaming, working, or content creation where a quieter system makes a noticeable difference. The Cybenetics Gold efficiency rating and 105°C-rated capacitors add confidence for long-term use, while Modern Standby support rounds out the feature set for today's PC platforms. Overall, the CORSAIR RM850e is a well-rounded power supply that combines strong output, modern compatibility, quiet performance, and clean cable management. It's an excellent foundation for a powerful gaming PC or workstation and leaves plenty of flexibility for future upgrades. 💻⚡✨

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.

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.

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.

Very intuitive to install, had every cable I needed (12v high power connector), High quality feeling. Only complaint is slight coil whine, but that’s to be expected with any PSU when under high load. Would recommend to anyone.

Provides power for all components as expected. Comes with all needed power connections.

High build quality, and the small size makes cable management easy in bigger and smaller cases. The included cables are very nice, and are aesthetically pleasing as oppose to most PSU's. Also very quiet on idle I can't even hear when it turns on under load.

I'd been using Corsair products for a long time and it does not disappoint. I'd only used it for a short while but I expect it to last for a long time.

Setup - 10/10 Packaging came with zip ties for cable management. Cables were clearly labeled and I had no difficulty attaching them to the motherboard. Also came with the necessary screws to attach the PSU to the case. Noise - 8/10 The sound of the fan is extremely quiet as advertised however it is definitely noticeable when under moderate-heavy usage. Performance - 9/10 I may update this rating in the future with this being a recent purchase and all. However the PSU functions as advertised out of the box and is able to handle everything I’ve thrown at it.

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?

Great modular cable with plenty of power. Fits in the case easily and has an included 12 pin graphics card cable which was great for my card. Plenty of left over cables.

a Fonte funciona perfeitamente, porém nao vem com o cabo que liga na luz, o que não faz nenhum sentido. Tive que adaptar com uma que já possuia.

Le gustó mucho a mi hijo como funcionó junto con la tarjeta de video que le instaló A su pc gamer, muy útil y lista para usar
