OP

The power consumption of the MPU isn't that relevant. The fact is that without the MPU connected you have good 5 but with it connected only 4.12v which is not high enough for the board to boot.

There is either a problem on the power supply board which means it is failing under load or there is an issue with the MPU board with the 5v shorting to ground somewhere.

1) Do you have some other game you can test the power supply board in?
2) Do any of the chips on the MPU board feel warm when connected to the power supply board?
