So trying to build a new AMD based system, but having no such luck - the power LED and CPU fan turns on, but no POST beeps or BIOS screen. Specs and list of things I've tried below. Any suggestions?

Specifications (all parts are brand new unless noted otherwise):
CPU: AMD Ryzen 3 1200
MB: Gigabyte GA-A320M-S2H
CPU Cooling: Stock AMD fan
PSU: Corsair CX-430M (used from another system)
Generic system speaker

With this combination I get the power LED and CPU fan turning on, but nothing else...no beeps, nada

What I've tried:
Different motherboard (Asrock B450M Pro 4)
Different CPU (AMD Athlon 3000G)
Different PSU (Corsair CS-550M, used from another system)
Different system speak (speaker works ok in another PC)
Removing CMOS battery for ~30 mins and then reinstalling
Resetting CMOS jumper
The pinned diagnostic list from 2009 in this forum

So, I've tried different combinations of MB, CPU, PSU, CMOS, system speaker and nothing:( The only thing I haven't changed is the system builder i.e. me🙄

Any suggestions on what I'm missing?
