Questuon for OG PC Hardware Guru's

I got a new MSI z590m mobo and the thing wont post or show any signs of life. I put it on the bench since it did fuck all after i installed the thing already.

Question before i send it back

It should just need the 24pin, 8pin, cpu, cpu fan, hdmi connection, and RAM installed for it to post right?

I can also feel the heat sink get pretty hot just having the psu connected without the unit being operational which seems suspect to me there is a short somewhere. I tested the psu and its fine (agk850).

I tested my old mobo on the same bench and got it to post but its an atx vs a micro atx so i wasnt sure if there is something else stupid i need to connect

Are you sure the power supply is good? Sometimes that can cause problems like this even though it’s powering up.

Sorry. Just read that you test another board successfully with it.
