A couple of tagan psus:

seem to both give 180w on 3.3/5v lines, at 24a/30a but I guess they are borderline for this board.

FWIW there's a cheap-BIN a7m-266d on ebay uk complete with cpus and 2gb ram. Damn these psu requirements 🤣.

I liked the board so much I went and bought another one.
this one has slightly faster cpu's 2000+ athlon's (compared to the others 1900+)
here is a pic of the board when testing:
