@tvad- You can try Keces P8 Linear Power supply or Uptone Audio JS-2 Linear Power Supply. Either one would work but the stock MacMini 2012 model needs an internal power supply upgrade to be able to use the 12V Linear Power Supply input. The Uptone Audio MacMini DC conversion kit would be an easy way to upgrade the internal power supply of a MaxMini 2012 model. Here is the link.

I don't know how to upgrade the internal power supply of a newer version of a MacMini but there are vendors in the market who could do that for you.
Thanks.
