Abstract: In one embodiment, an apparatus generally comprises a power delivery board for integration with a printed circuit board, the power delivery board comprising a power plane for delivering power from a voltage regulator module to an application specific integrated circuit (ASIC) mounted on a first side of the printed circuit board. The power plane in the power delivery board interconnects with power vias in the power delivery board for vertical alignment with the ASIC through power vias in the printed circuit board to electrically couple the voltage regulator module and the ASIC when the power delivery board is mounted on a second side of the printed circuit board.
