1. An adjustable power supply system, comprising:
a power module providing an operating voltage;
a device power supply electrically connected to the power module, the device power supply performing a power supply operation and providing a supplied power to a device to be tested according to the operating voltage; and
a control circuit, wherein the control circuit outputs an adjustment signal to control the power module according to a power consumption status of the device to be tested, so that the power module generates the operating voltage according to the adjustment signal, and the device power supply generates a first power dissipation that is less than a predetermined power.
