Once the power supply (SMPS) is connected, it sends a 5V standby voltage (purple wire) to the Super I/O (SIO) chip. RSMRST# Signal:

When the power supply sees PS_ON# hit ground, it switches on its primary internal rails, flooding the motherboard with: (For CPU VRM, GPUs, and fans) +5V (For USB, drives, and logic) +3.3V (For PCIe slots and basic IC power) RAM and Chipset Voltage Rails desktop motherboard power sequence pdf exclusive

Once all voltages are stable, the SMPS sends a "Power OK" (grey wire) to the SIO. The VRM also sends a "VR_READY" signal to the PCH. Platform Reset (PLTRST#): The VRM also sends a "VR_READY" signal to the PCH

The PCH verifies that all power components are satisfied. It releases the Platform Reset signal ( PLTRST# ), which resets the PCIE slots and onboard peripherals. Right after, it sends the Platform Reset signal to the processor ( CPURST# ).
