I have a 10amp din rail 5v PSU I want to power a Pi 5 which wants 5amps over USB C and a few other things I want to also power, USB hub and maybe some fans but never more than 75% load

But the USB-C pinout has got me confused

Do I need to run live to all 4 power pins and gnd to all 4 ground pins to supply 5amp?

I assume this is wired in parallel right??? So they can use a smaller gauge cable

And I reading this right?

Thanks
