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

Remix

In 2015, Corsair launched two new series to replace the RM series: RMx and RMi. Of the main differences, the representatives of the latter have a Corsair Link system and a fluid dynamic bearing fan, while the models from the RMx series have a screw-threaded sleeve bearing fan, which has a shorter service life. For this money, I would like a fan on a hydrodynamic bearing, but we have what we have. We hope that its durability does not let us down. But the capacitors in both series are claimed exclusively Japanese.

Impressive power reserve

The youngest model in the RMx line according to the passport has a power reserve of 550 W and boasts an impressive efficiency of 92%. In fact, it turns out even better, since at a rated power of 550 W it coped with overloads reaching a value of 645 W without any problems, while ensuring minimal output voltage deviations. I especially liked the state of the 12-volt line: no drawdowns, regardless of power consumption, and the ripple level is 2-3 times lower than normal. Add to this the high load capacity of the +12V channel and the presence of all types of protection, and we get an excellent basis for creating a performant gaming system with one or two video cards and with the possibility of further overclocking.

Corsair Link digital interface support

Of the additional goodies, we highlight a modular structure, a hybrid cooling system (normal and silent mode) and an unusual Corsair Link hardware and software system that allows you to monitor the state of the power supply in detail. For it, you just need to connect the power supply to the PC using a USB cable and install proprietary software, after which you will have access to all the additional functionality of the device.
