Mac mini DC-Conversion / Linear Fan Controller Kit (MMK)
For modern Apple Mac minis (model years 2010, 2011, 2012, and 2014), our unique Mac mini DC-Conversion / Linear Fan Controller Kit (MMK) performs several functions important to elevating the audio performance of this compact computer. [The MMK is not currently compatible with Mac mini model years 2018 or 2020.] The MMK converts a Mac mini to operate on external 12V DC power by replacing the computer's stock switch-mode power supply with a circuit board that fits perfectly in the space vacated by the SMPS. There is no soldering and no cutting of wires required, the procedure is completely reversible, and a toolkit with detailed instructions is provided. The MMK also provides a carefully chosen amount of filtering (a pile of filter caps after a regulated external supply is not good for performance). Conversion of a Mac mini to accept DC power is not new, and pairing the computer with a high quality external linear power supply is one of the best upgrades you can perform on this popular
