Cooler Master MasterWatt power supplies have a power of 450 to 750 watts, while the efficiency of these models reaches 85%, which is confirmed by 80+ Bronze certificates. All representatives of this series are of the semi-modular type. This means that when assembling a gaming or working system, the user can unfasten some of the unnecessary cables, thereby simplifying cable management.

All models in this series belong to the middle class and can boast of interesting features that low-cost power supplies lack. For example, they are ready to work in a wide range of input voltages and are equipped with DC/DC converters, with which the input voltage can be calibrated at the macro level.


The integrated cooling system uses a unique self-lubricating slip bearing Loop Dynamic Bearing. In addition, MasterWatt power supplies can operate in a completely silent passive cooling mode if the total energy consumption of the system does not exceed 15% of the nominal value. In addition, the compact dimensions of the MasterWatt 650 will allow you to install the unit even in small enclosures.

These power supplies are designed for medium and high-performance working and gaming systems, which have increased requirements in terms of energy efficiency, reliability and noise level. As for the model range, models with a capacity from 550 to 750 watts are most often on the market, but after a series of positive reviews in the media, Cooler Master expanded the range with 450 and 1200 watts models, as well as highly specialized gaming models with the TUF prefix. All of them are provided with a 5-year warranty from the manufacturer.
