I was recently asked to add a feature to the Mini ATX PSU so that it will remember its power state in case of power interruption.  What this means is that, if the Mini ATX PSU is powering the Raspberry Pi at the time of power interruption, then it will automatically reboot the Pi once power is restored.  Also, if the Pi was off or booting down at the time the power goes off, then it will stay off when the power comes back on.

Since I'm not sure everyone would like this feature, I've made it a programmable option.  For more details, please go to my Tindie store: https://www.tindie.com/products/tomtibbetts/piryte-mini-atx-psu-for-raspberry-pi/
