I can tell you in a couple of days when mine arrives, but right now it's stuck somewhere in transit because of the holidays. Next week I hope, but could be longer.
The shipping took a long time but it finally arrived today. The Joyo power supply 2 does not fit under an unmodified PT Mini. The first picture shows there's no problem with space for the cables. However, in the second picture I hold a ruler across the PSU to show the power supply is too tall for the PT feet, and this even before adding velcro.
You're welcome! My Mini is already modified, I've raised two feet to make room for a G30 wireless reveiver under the board.
