As of now, nearly every P2 model fulfills the criteria needed for the 80 plus rating. It offers a flexible cabling system that one can easily adjust as per his system needs. 

Apart from that, it gives you a semi-automated functionality, and the option to customize it completely in case you want the fans to work longer.  

Performance

The PSU works through DC and DC converters. It is designed to run for long hours with 50C temperature and is backed by the ATX.  

Coming to the main highlights of this unit, for protection, the OC here is changed by OPP.  However, one of the main drawbacks is the unavailability of an OTP. It is an essential feature in the majority of power supply units that are semi-automated. 

Moving on, this model is also equipped with a dual cooling fan. Considering all the core specifications and features so far, especially the dual cooling fans, they hardly make any noise when your system is turned on.

Introduction 

This model is probably one of the less demanding power supply units from Corsair. The maximum range for power is 550W and it scores a perfect 80 PLUS Gold rating. Moreover, it comes with a complete modular cable system, and it gives you a powerful performance without being too loud and noisy. 

Features 

Earlier, Corsair revamped its RM range by releasing more power-oriented power units that were equipped with a complete digital user interface. This helps users to easily keep a track of all core statistics to handle the fan. 

But now, it seems that creating a more budget-friendly model is the maker’s topmost priority. Therefore, you don’t get any fancy interfaces or circuits in this unit. 

This line features a total of five winning models that are ranked among the best PSUs for ryzen 7 3700x. 

Its power ranges between 550W and goes as far as 1kW. Since this is an elementary level unit, the features are selective but useful. All units under this line feature CWT with Gold efficiency. 

Its design is a modular one and therefore, no cables or wires are permanently attached to the device. 

Performance

The fan won’t run if the workloads don’t reach up a certain level. Here, Japanese capacitors are used as the primary ones. Moreover, these capacitors are used in nearly all variants of this unit.  

They help to keep your system more safe and secure. And without it, you cannot experience the level of performance that’s associated with the best power supply for Ryzen 7 3700x. Moreover, it makes the unit last longer too. 

If you opt for power supply units with Chinese capacitors, they won’t give you the same performance as a Japanese capacitor would give. 

Chinese ones work on less powerful electrolytes and therefore, it makes the system age more quickly. And if you are using it in more extreme temperatures, then it is bound to age even more quickly. 

And therefore, more premium ones such as Japanese caps are recommended for power supply units. 

Summary

Nearly all minor rails provided are powerful enough to work with 550W units effortlessly. And you can use all kinds of graphic cards no matter how powerful they are. 

The connectors are good enough for running a 550W power supply unit. However, it would have been better if it provided more connectors.
