Fixed that for you.
Anyway, the maximum power consumption of the M4 Pro mini is listed as 140W, or 155W, depending where you look (I guess there's various ways of measuring it). Interesting debate as to why that's so much more than a MacBook (I'm assuming that a MacBook has the battery smoothing out periods of high demand - a Mini would just crash) - but the aforementioned bean counters wouldn't have specified a 150W PSU if a 100W one would do!
So, fine, the current USB-C Power Delivery standard goes up to 240W - but few current power supplies would deliver that: the Studio Display offers 96W. The Caldigit TS5 dock might work at 140W but that;s borderline on a $$$ dock, the Caldigit Element Hub only has 60W... same for a lot of USB-C displays. So, at best, "BYOP" is likely to mean Buy your own power rather than using something you already have to hand. If USB-C power doesn't let you power it from a display or hub/dock and, instead, requires a dedicated power brick then the feature seems pointless.
