"...needed by a power supply?" The power supply itself, unloaded, needs very little power to be on.

If you mean to ask "How do you know what power rating to choose when selecting a power supply?" This is determined by adding up all the loads that will be attached to the supply.

For instance, for a PC you can add up all the wattage demand of the mother board + video card + hard drives + all other components, plus 30%; then select the supply with the closest wattage rating above the sum of your components.

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.
