Embodiments include apparatus, methods, and systems having a multi-chip module with a power system and pass-thru holes. An exemplary electronic module includes a first portion having a first printed circuit board (PCB) with a memory and plural processors. A second portion has a power system and a thermal dissipation device. The thermal dissipation device has plural extensions, and the power system has plural pass-thru holes. The first portion electrically couples to the second portion to form the electronic module when the plural extensions extend through the plural pass-thru holes of the power system and through plural pass-thru holes of a second PCB disposed between the first and second portions.
