What pieces of information are needed before selecting a power supply?
The main piece of information needed is the load wattage or amperage that will be connected to the power supply. Once this is known the power supply of a greater size that the load should be chosen. Also with this information the size of the wires can be calculated from the power supply to the load. Too small a wire will create a voltage drop at the load end of the circuit. This will cause under performance of the load.
