Abstract
A computer system includes a power supply unit (PSU), a matching circuit, and a chip. The matching circuit includes a voltage conversion unit, a voltage-dividing unit, a first resistor, a comparator, a diode, and a delay unit. The comparator includes a non-inverting terminal electrically coupled to the PSU to receive a power-good signal, an inverting terminal electrically coupled to the voltage-dividing unit to receive a reference voltage, and an output terminal. The delay unit is electrically coupled to a power supply and a power-good signal pin of the chip. When a voltage of the power-good signal is greater than the reference voltage, the output terminal of the comparator outputs a high level signal, the diode is turned off and the power supply is delayed by the delay unit and then output to the power-good signal pin of the chip.
