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
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.

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. Ihor: use Corsair CP-9020179-EU few months |
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  wawan: use Corsair CP-9020179-EU more than year |

In 2015, Corsair updated its RM power supply line twice, which the company thought were good, but not perfect. First, the RMi line entered the market, which used high-quality Japanese capacitors and added the Corsair Link system to monitor the status of the power supply. Not everyone needed this thing, so a little later RMx power supplies arrived on the shelves with the same element base and Japanese capacitors, but without Corsair Link. It is about this model that we will discuss in this review.
Efficiency 92%
According to the passport, the model has a power reserve of 650 W and boasts an impressive efficiency of 92%. In fact, it turns out even better, since at a rated power of 650 W it coped with overloads reaching 730 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.
10 years warranty
Among other advantages, we note the high load capacity of the +12V channel, the presence of all types of protection, a modular structure and a hybrid cooling system that allows you to switch coolers from normal to silent mode. A useful feature if the computer is used not only for games. Together with a 10-year manufacturer's warranty, this makes the Corsair RMx a reliable base for a powerful workstation or gaming machine with a couple of video cards and serious overclocking.
