I missed that (or read it as a couple of PSU outputs). Point to you.Post #8 and Post #9. I said use a couple of PSU units. You can make the outputs floating and add them up.

Note, the combined output will have poor regulation and noise performance, both outside the ATX spec. Also, there is a chance that one or both outputs will oscillate under some load conditions as the two control loops get into a fight.
