Zusammenfassung:	A power supply apparatus with soft-start function is suitable to a load including a voltage stabilizing unit and a load unit coupled in parallel. The power supply apparatus includes a power unit, a soft-start adjusting unit, a current detecting unit and a controlling unit. The power unit generates a power voltage. The soft-start adjusting unit receives the power voltage, a first controlling signal and a second controlling signal, and transforms the power voltage to a soft-start current accordingly to output the soft-start current to the voltage stabilizing unit or output the power voltage to the voltage stabilizing unit. The current detecting unit measures a current of a loop formed between the power unit and the voltage stabilizing unit to generate a current detecting signal. The controlling unit receives the current detecting signal to generate the first controlling signal and second controlling signal.
