I have always understood a power supply will maintain its output voltage up until it reaches the output current capacity. That is to say a power supply with a 12 volt output and a 20 amp capacity will be able to maintain an output voltage up until the current draw reaches 20 amps. After 20 amps??? but that's fine it is now being used beyond spec.
Is this a correct understanding or have I missed something all these years?
