Please have no fear of a power supply internal parts as long as
the AC supply is disconnected. This means UNPLUGGED FROM
THE WALL OUTLET.
As long as the power supply is connected to your mother board
there will be no voltage stored in any capacitors that will be
harmful. The load of the mother board, hard disk and floppy
disk will discharge and consume any power in micro-seconds.
