The rated output current is the maximum load current that a power supply can provide at a specified ambient temperature. A power supply can never provide more current that it's rated output current unless there is a fault, such as short circuit at the load.

Power consumption is the amount of input energy (measured in watts) required for an electrical appliance to function. This is opposed to power output which is a measure of the level of performance, of a heat pump for example.
