What PSU connector is used?

Planning a battery powered MAC Mini 2018. It seems to have an additional row of pins compared to the previous 85w 2014 model. Does anyone know the pin out of this, and also if apple’s using a custom connector or if it’s a standard one I could find and crimp? Thanks!:)

Here’s a picture of the power supply:

The logic board header is a standard 20 pin.

Its not a simple replacement! As there are multiple voltages coming from the power supply.

Its just smarter just getting a DC to AC converter to run on a car or boat battery.

Many of todays trailers & cabin cruisers offer AC outlets which are directly wired to the motor or generator.

Thanks Dan - upvoted! I noticed the header looked “keyed” in the highres picture in the teardown, but might’ve just been my imagination. Considered using an inverter but trying to avoid the wasted energy in the conversion process. Keyed connector aside, Do you know if the pins are “paired” - the connectors under the soldermask seem to be linked vertically? Otherwise no worries happy to stick a multimeter probe in the outputs ;)

You really can't do want you want as there are multiple voltages.

Just like a PC you'll have 12 volt and 5 volt circuits and you'll have multiple circuits besides multiple wires servicing the same circuit and you still have a switch line and SMC sensor line mixed in here as well.

So as much as you want to by pass the power supply it's just not possible at this location!

Your only hope is to get a spare so you can take it apart. so you can redesign the unit.

Here you would strip away the AC part of the circuit and insert a DC version. So you end up with a DC to DC power supply.

And, yes the connector is keyed
