B550m-ITX
Ryzen 5600g
32 gigs ddr4
1tb samsung 980 ssd
Evga 650w supernova

Motherboard, CPU, and SSD are brand new and my psu and ram we're working in the last pc i built.

Just put the build together and it wont post, I've tried with the case io and by shorting the pins. I disconnected and reinstalled every power connection and still get nothing. How do i know if this motherboard is DOA and what can i do about it?

For this CPU You must have at least BIOS version 1.60
It should be printyed on a small sticker, like P1,xx
If the BIOS is not suitable, for this CPU, You can conatct AMD support, they can borrow You a boot kit, with which You can flash the BIOS.
