A compliant USB-C source will not provide more than 5V/3A without PD negotiation period, and is only guaranteed to provide default USB power. So if you can potentially draw more, you need to check whether it's allowed.

You need a chip in the power supply for that, but you already have a chip in the power supply because switching supplies are massively cheaper.

You don't need a marker chip in the cable unless you intend to go over 20V/3A.

I'm just talking about end devices here (source/sink).
