Motherboard repair

[gtrak]

Hello folks, I have a ASUS X399 motherboard. I blew it up by plugging in a PCI-E card backwards when off, shorting some standby voltage. I smelled some smoke, and now the power button does nothing. I think I found what I blew up!  I found a hard bubble on top of the top transistor in that pictured cluster.

I have a picture from a replacement board, but can't seem to identify the component.

Can you fine people help? If it's really as easy as replacing this, it's definitely worth a shot for me to try it.

WAG71??

I found one hit for the WAG marking that sounds promising, PDTA144VT which is a PNP transistor in a SOT-23 package.

I was able to source some PDTA144VT,215, will give it a try, thanks!

any pnp 'big' enough will pass the test ... or not
