CorsairRM1000x Fully Modular ATX Power Supply - 80 PLUS Gold - Low-Noise Fan - Zero RPM - Black

Pros:- Only plug in the cables you actually need - simplified cable management- Quiet fan that only kicks on under load- Straightforward install, great for hobbyist-level buildersCons:- I didn’t find it soonerFull Review:I brilliantly managed to short out the power supply on my PC (PSA: Don't plug a USB-C cable into a USB-A port if you don't want to risk taking out your power supply...), and I bought this Corsair RM1000x in a pinch because it would arrive the quickest. I’m more of an inquisitive hobbyist than a tech expert so had assumed a power supply is just a power supply, but this one had a few features I lucked out on.Super clean and minimal cabling - no medusa-style tangle of wires coming out of the box, just plug in what you need. It took care of the rats nest I had previously by not having to hide the unnecessary cables inside the case. As for the cables I did need, I have an ATX mid-tower case and cable lengths were perfect - not too tight or too slack.The fan stays off during low-demand tasks, then spins up when I’m processing video or doing something more power intensive. It’s quiet when it does turn on, and most of the time it’s completely silent.If you’ve ever blown a power supply and need a replacement you won’t regret, this is it. Honestly, I wish I had this one from the start — it’s one of those parts that just works and makes your build cleaner and quieter.

Great unit! A-tier unit with solid performance and good reviews. High quality. I haven’t seen the fan spin yet (not like I do a lot of high power consuming tasks) but this PSU powered my 9800x3d and 5080 flawlessly.Super quiet. Cables are good! The length is adequate I wish it was more compact for SFF cases. I would go for SF1000 doesn’t come with a native 12-pin connector so I decided to give it a try. Sure enough - too large for my case (Lian Li A3) as I have a real large 5080 that takes almost entire space in it. With an AIO 360 it’s simply not an option. For those of you who attempt to build in A3. So I will most likely go for a good air cooler instead and keep this unit. Love it.

This has been a solid power supply for my first build. Powering a Ryzen 9700X and Radeon 7800XT, everything has been great. The modular design made building quite a bit easier, although there is a considerable lack of documentation. I had to piece together what cables go where from online tutorials and the words "PCIe" and "CPU" on the component-end of the cables. Otherwise, the cables are solid feeling, if a little stiff.

It does its job and provides power to my PC components with a fantastic gold efficiency rating. This version is also smaller than Corsair's previous 1000 watt PSU, but have had no troubles of overheating at all. The fan control knob is also a nice feature to have if you really want to control the speed of your PSU fan. Cables are also easy to connect and disconnect with no problems at all and the dedicated 12v-2x6 port is great to have since it lessens the amount of cables needing to connect to your PSU.

I recently purchased the Corsair RM850x (2021) Fully Modular ATX Power Supply, and I must say, I am extremely impressed with its performance and features. Corsair has always been known for delivering high-quality power supplies, and the RM850x is no exception. Here's my review of this remarkable power supply.First and foremost, the efficiency of the RM850x is outstanding. With its 80 PLUS Gold certification, it delivers excellent power efficiency, ensuring that my system consumes less energy and runs cooler. This not only helps in reducing electricity bills but also contributes to the overall longevity and reliability of my system.The fully modular design of the RM850x is a game-changer. It allows for easy cable management, as I can connect only the cables I need and keep the rest neatly stored away. This not only enhances the aesthetics of my build but also improves airflow within the case. The modular design also makes installation a breeze, as I can effortlessly connect the required cables without any clutter or hassle.One of the standout features of this power supply is its low-noise fan. The fan operates silently under regular loads, and I barely notice its presence. It only kicks in when the system is under heavy load, and even then, the noise levels are impressively low. The Zero RPM fan mode is particularly noteworthy, as it ensures complete silence during idle or low-power usage scenarios. This is a great feature for those who prefer a quiet computing experience.The build quality of the RM850x is top-notch. The unit feels solid and durable, and the black finish gives it a sleek and premium look. The cables provided are of high quality and have a premium feel as well. The power supply comes with all the necessary protections, including over-voltage, under-voltage, over-power, over-temperature, and short-circuit protection, ensuring the safety of my components.In terms of power delivery, the RM850x handles my system with ease. It provides ample power for my high-end components, including a demanding CPU and a high-performance graphics card. The voltage regulation is excellent, and I have not encountered any stability issues or power-related problems since installing this power supply.One minor drawback of the RM850x is its size. It's a bit larger than some other power supplies on the market, so it might not fit into smaller PC cases. However, in most standard ATX cases, this should not be an issue.Overall, the Corsair RM850x (2021) Fully Modular ATX Power Supply is an exceptional product that delivers on all fronts. Its efficiency, modular design, low-noise fan, and solid build quality make it a reliable choice for any PC enthusiast or gamer.
