Plugged in power supply wrong, electrocuted the mini?

I managed to insert the power plug in the wrong orientation. It's in the back in an awkward position, it's always a tight fit so I just tried a bit harder...until there was a spark. Shockingly, the mini won't turn on anymore.

I've measured the power pins and they show no significant voltage, so maybe it's just the power supply. However I'm not sure if voltage is even expected, there are more pins then strictly needed so maybe it's a "smart" power supply that the mini has control over.

Wondering if I'm the first idiot to do this or if someone else has already risen from the ashes with some good advice for me at this point.

update: got it working, the power supply is busted but I was able to salvage the power cord and get it running from a benchtop supply. The ADT-150C24AC datasheet has a helpful pinout.

The show must go on lol

RE:

Maybe you got lucky and just blew a fuse on the main board.

You need to speak the the help desk, use the chat function NOT email.

I made the same mistake with my Mini and ADT-150C24AC PSU. The PSU was smart enough to shut itself off, causing no damage to the Mini (kept the fuses intact). The PSU needs to be power-cycled for it to work again.
