I am not familiar with the power stacking but you can bet your arse that you should have a "PS required +1" number ob PSUs in the stack. Your 9 switches may be able run off three PSUs but if one blows up you all of a sudden have a down stack. I'd be adding the extra one all the time. Unless I have this completely wrong ;)
