Interesting thought, I looked it up out of curiosity and fund 155w max (but realistically more like 80w sustained) for the mac under load, and just around 20watts for the brain, surprisingly almost constant whether “under load” or not.

> 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.
