Selecting power supply unit for an embedded system
You need to break down ALL of the supplies into Voltage, Amperage and Wattage.
- why don't you tabulate that in the question?

Once you have that then you can calculate the total wattage, and compare it against the various options you have for required Voltages vs. the current at each voltage.

You should expect to over size each supply by 15% (although others may have a different opinion on that)
