I Am Not an Electrican Engineer, But My Boss Is. I did this once, and
he had a cow. There was some problem he yelled at me, having to do with
different PSUs pulling voltage up at a different rate. There's someway
he said that the differential in voltages would feed back through the
IDE channels, for some reason....
The short of it was that someone qualified to judge said it was a really
bad idea to use multiple seperate power supplies.
