Model overview based on user reviews  
The Corsair RMx Series power supply units are praised for their silent operation, with the fan activating only during heavy gaming or 3D rendering, ensuring a quiet experience during normal use. Users appreciate the reduced need for cleaning, as the dust filter remains clean even after several months of use. However, there are some drawbacks, including the high price and the absence of a promised 10-year warranty in certain regions due to the lack of authorized resellers. Additionally, the cables are noted to be very rigid, which can be inconvenient during installation, especially in certain cases where the wire length may be insufficient. Despite these issues, the PSU is considered reliable with no noise or voltage fluctuations, making it a worthwhile investment for those prioritizing quality and performance.
Pros

Cons

Quietly working, but still minuses
21 February 2024 
Practice 2 days of 10-12 years per day. There is no complaining.
+ The fan turns on only during heavy gaming and 3D rendering, in normal mode it does not spin;
+ Previously, I cleaned the dust filter near the PSU once every 2 months, after the upgrade and 7 months of use, I have never cleaned the filter, there's no need.
- Bite the price;
- The promised (on the official website) 10-year warranty is missing because there is no authorized CORSAIR reseller in Ukraine;
- Very stiff wires, as soft silicone ones have been invented long ago, and at this price, they could have been replaced;
- When mounting in a Fractal Design Define R5 case, the wire length is insufficient, some have to be stretched a lot.

It's unclear what the money is for.

If the money is burning a hole in your pocket, then you can go for it.
+ The cooler only turns on during heavy gaming and 3D rendering, it doesn't spin in normal mode.
+ I used to clean the dust filter near the PSU every 2 months, but after the upgrade and 7 months of use, I haven't cleaned it once because there's no need.
- The promised 10-year warranty is missing because there is no authorized CORSAIR reseller in Ukraine.
- The cables are very rigid, considering that soft silicone ones have existed for a while, and for this price, they could have been replaced.

You can take it, that's for sure (youtube.com/c/wawanxxx)

I took this PSU with the thought that it was impossible to save on a PSU, it was certainly possible to take a PSU cheaper, but it so happened that I took this one with a limited budget, I’m not very upset
Silent up to 300 W, I’ve been sitting without a video card for a year, it doesn’t make noise, it doesn’t whistle (throttle), no ripples and drawdowns in 12v, 5v, 3.3v lines, 10 years warranty
In principle, the price is high, and so everything is buzzing
