If you are using a bus powered audio interface then you need to build that into the equation. If using a regulated supply, the crunch occurs during boot as current draw can peak at over 4 amps. 8 to 1.5 amps at 12 volts or 10 to 20 watts. However.ĭepending on what is installed in the Mac Mini such as hard drives, SSD's and RAM, basic current draw can be in the range of. The mod removes the internal AC supply and then makes a direct connection from an external DC supply to the Mac Mini's main board which no doubt has it's own DC-DC conversion. My 20 models would work just fine off the over 17 volts of a freshly charged V-Lock battery. The Unibody Mac Mini's will run on a wide range of DC input voltages.
