> 155w max (but realistically more like 80w sustained)

155W PSU seems to be unified with M4 Pro model, plus there's reserve for peripherals (~55W for 5 USB/Thunderbolt ports).

Apple lists 65W for base M4 Mac itself: https://support.apple.com/en-am/103253

Notebookcheck found same number: https://www.notebookcheck.net/Apple-Mac-Mini-M4-review-Small...

I clocked my M4 at 108 Watts while running inference using Qwen3.6-35b-a3b via Al dente.
