If you are going to install a RS4 or RS5 sound board, you need the generic RS power supply to power it.  If you leave the Signal Sounds board in, it'll work without any additional boards.

You don't need any motherboard for the RS4 or RS5 boards, you just need the 691RSPRA00 power supply and the RS audio board.
