Perhaps a high end 450W power supply (cost divided by 4) with a custom "Y" cable from a cable maker. In quantity the cables might be cheap enough. Someone will have to calculate a power budget for each voltage. It would be best to also measure an actual system's current draw on each rail, under full load to verify. You would probably require several hundred (4 board) systems to justify the initial design costs.
