Buyers, be aware
The description is somewhat misleading, as the 2024 refresh is a platinum power supply masquerading as gold (lower). The box and cybenetics website confirm it. That is a great performance anywhere near the price point.Well, always nice when a product delivers over the target spec rather than under, so kudos for Corsair. From the user perspective, the psu is great, runs rtx 5090 with no or minimal noise, the cables are individually sleeved and of high quality you’d expect from Corsair. This also helps quickly check the 12V-2×6 connector by hand to make sure no individual wire is super hot. The 12V-2×6 connector has a good latch and locks solidly.Clean, minimal packaging, easy to install. There are enough connectors to power almost any reasonable system. Overall, if you have gotten to this review, I strongly recommend buying it for most any use case in 2025.

Stability, ease of use, quiet, and a well established design.
Bought this 850 watt unit 6 months ago and just now last week installed it. Everything went smooth, my son did most of it, no problems with cables or routing or anything. I love the feature of being able to control the fan speed.This is a well built, well known PSU. It is performing as expected, which is quiet, cool and stable.Highly recommend this unit from Corsair.

Incredible PSU
The Corsair RM850x is a solid choice for anyone building a high-performance PC. Its fully modular design makes cable management a breeze, and the included cables feel both durable and flexible, allowing for a clean and organized setup. One of the standout features is the ability to control the PSUâs fan noise levels, which helps maintain a quieter system under different loads. Additionally, its A+ rating in PSU tier list confirms its reliability and efficiency. Overall, it’s a great PSU for the money

The RM1000x is an excellent PSU with individually sleeved cables.
I bought this Corsair RM1000x ATX 3.1 (2024) PSU to replace a faulty ASRock PSU. As one other review mentioned, the Cybenetics rating on the box for power efficiency has been recently updated from Gold to Platinum, which will help keep long term energy costs down for people who live in areas with expensive electricity.When unboxed, the power supply feels and looks like a premium product, and indeed it is. The modular cables in the box all come with individually sleeved wires, and the 12V 2×6 connector and ATX 24 pin connectors come with clamshell style cable combs preinstalled, which seems to be a newer development with this unit. I looked at multiple tech site reviews of this power supply and the only one with cable combs I found was the Kit Guru review, and those were manually installable traditional style combs.The cables did have a bit of a petrochemical smell to them, but it was far better than the ASRock unit I replaced. The cables on the RM1000x are also longer and more flexible than on the ASRock unit, making routing in my mid-tower case easier, specifically for the CPU (length) and ATX 24 pin (flexibility).The power supply performs exceptionally well, making absolutely no coil whine noise at any load, and works completely silently at loads below 500 watts. The fan control knob on the back of the unit comes out of the box set to 0 RPM low noise mode, leaving the fan off until the aforementioned 500 watt limit is exceeded. If you don’t care about 0 RPM low noise mode, you can adjust the knob clockwise until it clicks, at which point you’re manually controlling the fan, allowing you to set a constant fan speed anywhere in the fans RPM range.One thing to note is that the 12V 2×6 connector that comes in the box only has 2 of the four sense pins, but this is totally fine, as it powers my RTX 5080 without issue, so don’t be concerned that two sense wires are “missing”.I was extremely lucky to get this unit at a cheaper price only a day before it raised to its current price, but even around the $200 mark, this power supply is worth the price.Overall I give this power supply a 9/10, and only because I don’t like that the fan is gray instead of black, which honestly is likely a complete non-issue for most people.

Excelente fuente de poder hasta este momento. Reemplazó a una unidad de 750 watts que ya no pudo más.PROS:- Se siente muy estable el sistema y entrega de potencia.- Muuchas conexiones para más periféricos.- Conexión y cable de 12v para tarjetas gráficas que lo requieran.CONS:- Realmente ninguno de momento… Es algo pesada, pero es de esperarse…

I have to admit, when I first saw the knob on the back of the RM1000x that lets you control the fan or switch it to automatic, I was a bit nervous. I wasnât sure if Iâd mess something up or if it would be tricky to use. But honestly, this PSU completely exceeded my expectations.After 4 months of daily use, I can confidently say this power supply is game-changing. Itâs rock-solid, completely stable, and handles everything I throw at it, gaming, streaming, multitasking without a single hiccup. The fan control is actually a brilliant feature: I keep it on automatic, and itâs whisper-quiet unless things get really heavy.The build quality is top-notch, cables are easy to manage, and everything feels extremely premium. I feel like this PSU is going to last me years without any issues, and it really gives peace of mind knowing my system is in safe hands.If youâre looking for a reliable, high-performance, and versatile PSU, the RM1000x is worth every penny. After 4 months, Iâm extremely satisfied and canât imagine going back to anything else!

Works great! Love how it’s fully modular as I didn’t end up using all the cords. Only thing i wish is that the cords weren’t individual strands and are more covered.
