Couple semi random comments.I read 28 W somewhere, but it was a few weeks ago and I cannot find it now.
I will put an ammeter on the buck converter output at some point to check what the max really is. I have seen quotes as low as 12W (for the board only, I suspect i.e. not also powerig external devices: SSD, kb, mouse, Canbus HAT in my case)
I am using a 0.3m USB C: the manufacturer claims it is rated for 5A at 20V but I do wonder.
The main issue is that I have so far failed to find any USB C breadboard rated at more than 3A.
* 5V@5A is the pathological load with the CPU pinned and the USB ports maxed out. I had a Pi 5 running for months, booting from a USB connected SSD, powered via a audio HAT which was supplying 5.1V@2.5A. Had no power issues. Use case was always on desktop.
* 5A rated USB C cables exist. Look for USB C "power"/"charging" cables, USB-PD 100W cables and 5A emarked cables. They will become more common as USB-PD widgets become more common but are reasonably easy to find on Amazon.
