The chipset, including the northbridge and southbridge, is powered on. The chipset manages data transfer between various system components and provides features such as USB, SATA, and PCIe.

The power management circuitry generates control signals, such as reset#, standby, and power_good#, to manage the power sequence. These signals ensure that the system components are properly reset, powered on, or powered off. desktop motherboard power sequence pdf

The power management circuitry enables the power supply unit (PSU) by generating a power_good# signal. This signal indicates that the PSU can start providing power to the motherboard. The chipset, including the northbridge and southbridge, is

When the power button is pressed, the motherboard's power management circuitry receives a signal to initiate the power-on sequence. The power management circuitry, often implemented as a dedicated IC or a part of the chipset, takes control of the power sequence. These signals ensure that the system components are

The motherboard's voltage rails, including +3.3V, +5V, and +12V, are powered on. These voltage rails provide power to various components, such as the CPU, memory, and chipset.
