Safety & regulations

Louis Hirschmann (Germany)

The Silencer MK3 III is a good power supply. Externally, the PSU scores with its white paint, as white power supplies are quite rare. There are plenty of cables that have a nice length, and the modular cabling system ensures an efficient and convenient installation. We would also like to note that The Silencer MK III is made with high-quality components such as the primary capacitor. Because of its 80+ Bronze certification the Silencer MK III is more than capable of competing in its range on efficiency. The reasonable price and features make it earn our Gold award.

The 500W Silencer MK III is a perfect modular midrange power supply with reasonable price-performance ratio. Even at full load the 120mm fan is barely noticeable, doing justice to its name. It is only in the unlikely event of an overload that a slight noise might be heard. During our benchmarks the PC Power and Cooling Silence MK III displayed stable results that were well within the norms. Because of the positive impact that it left behind we give our Value and Silver award to this power supply.
