Hi,
I’m using an RP5. It is connected via a super big home made cable to a 10A power supply.
When I start it says the power supply is inadequate and it will restrict USB power. I have stuck a voltmeter to measure the output of the power supply and it never stops below 5.1 during boot, or indeed ever.
Before I start again with making a cable: maybe my soldering wasn’t good enough etc. I thought I’d check how does it know the power supply is inadequate?
The power supply and wire are both overkill and I thought my soldering was okay. It was only adding a 4 pad USB male connector to a wire, so not exactly complicated. I put shrink plastic on that end so I can’t measure the voltage there. Maybe there is a resistor on the USB-C which tells it the amperage is limited?
