I assume you haven't physically wired it as you show where +ve and -ve supplies are shorted to GND or you're going to get a loud bang as your caps explode.

Assuming that's not the case, why have you linked +PGND to the -ve supply and -PGND to the +ve supply and not the other way around?

Am I missing something here?

Try this thought. The top powersupply is a carbon copy of the bottom power supply. so the top of each power supply is positive, and the bottom of each power supply is negative. Series them together and you get 60 volts with a center tap. Connect the tops to the tops, and the bottoms to the bottoms, and you get parallel arrangement.

There really isnt a negative rail like with a regulated setup, its really just 2 30volt powersupplies thanks to the fact the center rail isnt connected on the pcb.

If you go back further you will see im really just connecting the positive posts of the caps together, and the negative posts together.
