Sounds more likey the PSU's fault than the motherboard. A defective motherboard isn't likely to kill an SSD. Remember that the only connection to it is the SATA.
motherboard is a loooong bit old, and the PSU checked out okay
im using it in the mini itx right now
im not really sure what the issue with the SSD is, nothing can read from it now after this. The motherboard would just lock up, even the restart buttons wouldn't work
