install question/issue

[Sehnsucht]

You just need the official power supply (especially for the Pi 4) and everything works fine. I've a Pi 4/official psu with an external usb 2.5" drive and it's rock solid. I'm using any old phone charger on a Pi 3 setup with the same drive (not running moOde) and this is also fine. Power supplies don't make devices sound better or worse - they're not in the signal path - they either provide enough power to run a system properly or they don't.
