CORSAIR RM750x 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.

I used this Corsair on a makeshift Plex Server build which is full of repurposed older parts, there was previously a 15 year old power supply in this case which needed to be upgraded so I picked 750w model for Corsair's reputation and it's power efficiency.The PSU is very silent, dead quiet because the fans don't run when it's at low usage. This Plex server build is only pulling approximately 80W under normal usage with the Corsair. On the ancient 15 year old power supply it was pulling approximately 120W under the same usage, so this Corsair power supply is giving me a 40W savings due to it's increased efficiency which is awesome.The build quality feels excellent and the cables provided are high quality and flexible making them easy to work with and route within the case. If you want to get fancy you could upgrade the cables to something like Cablemod cables but for my use with this Plex server it is not necessary as this wasn't meant to be a "pretty" build.This is my second Corsair power supply, I also have another model in my main system which has been running for a couple years without any issues. Most of Corsair's power supplies are on the high end of the PSU Tier list, google the PSU Tier List if you want to see it's exact rating among all other power supplies.

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.

Knowing Corsair's generally solid reputation for power supplies, and seeing good reviews on Reddit, I grabbed the RM1000x to support my GPU upgrade from an NVIDIA 2080 to a 3090. An online calculator estimated I only needed about 700 watts for my system, but I wanted power to spare for eventual use in my next build. This model definitely felt like a quality unit, which lined up with what I was expecting. So far, so good. It's been running smooth for about a month now and I have no complaints, just steady power.The modular cables were a nice improvement over my previous supply and made the upgrade pretty easy. I only plugged in what I needed, making the cable routing look much nicer in my case. It's quiet and reliable and I haven't had to think about it since the initial install. Of course, that is exactly what you want when it comes to a power supply! I feel confident this was a good value and money well spent compared to cheaper alternatives.

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.
