2). System Power LED ( Pin 15,16,17)
This 3-pin connector lights the system power LED when the

3). ACPI LED (Pin 7,8)
ACPI LED can use to control the blinking of a LED at the freqency of 1
HZ to indicate the system is at power saving mode

The system power is controlled by a push-switch, connected to this lead.
Pushing the button once will turn on the power and pushing again will turn
off the power. The system power LED shows that status of the system’s
power. If the power to the ATX power supply is interrupted while the
motherboard is on, standby power will remember that the motherboard
should be on and boot the computer when power is reapplied to the ATX
power supply.
5). Reset Switch ( Pin 1,2 )
This 2-pin connector connects to the case-mounted reset switch for
rebooting your computer without having to turn off your power switch.
This is a preferred method of rebooting in order to prolong the life of the
