Power Pisound via header?

I have an issue where I need to power the Pi 3A+ that I am using under the pisound via the PI header pins. I know I need a polyfuse to protect the pi. My question is would it damage the pisound to power the pi via the pin 2 of the pisound header?

My plan is to put the pollyfuse protected 5v+ on Pin2 and the ground on pin1.

It should be fine. :slight_smile:
