Well, to be honest, i only understood half of your question. Also, it depends a lot on which PSU you try to replace - A 520ST's PSU is different from one of a MegaSTE or an SH205.
I tried to look up some details about the PSUs used by Atari and found a rather outdated revision of Michael Ruge's Chips'n Chips:
Search it for "Netzteil" and you will find some data in the third or fourth hit. You do know that you will also need +5V and -12V along with the +12V, don't you?
