Motherboard power supply

Motherboard power supply section:-
  Motherboard get the power from two Port which are mentioned below
  1> ATX 20/24 pin port
  2> ATX  12V port
-ATX 12V port is used to supply the voltage to the CPU.
-Voltage at ATX 12V port is received from power supply which is converted into core voltageusing       the VRM section &then supplied to CPU.
- VRM[Voltage Regulation Module] section convert the 12V dc into 1V-2V ,40 to 50A.
