ATX12V Power Supply Connectors & Power Switch (POWER SW)
The P2S series mainboards prefer an ATX12V power supply. Be sure to connect the ATX
12V power supply plugs to the connectors in their proper orientation. The difference
between ATX12V power supply and ATX power supply is that ATX12V power supply
provides two additional power connectors: AUX power connector and +12V power
connector.However,the P2S series mainboard provide an unique design especially for
those who still use legacy ATX power supply(without AUX and +12V connector) as
long as their ATX power supplies can provide enough current on +12V rail(at least 8
Amperes). System stability with an ATX power supply is not guaranteed and we are not
responsible for any damage caused.
The power switch (POWER SW) should be connected to a momentary switch. When
powering up your system, first turn on the mechanical switch of the power supply (if one
is provided), then push once the power switch. When powering off the system, you
needn't turn off the mechanical switch, just Push once
Note: * If you change "soft-off by PWR-BTTN" from default "Instant-off" to "Delay
4 Sec" in the "POWER MANAGEMENT SETUP" section of the CMOS SETUP, the
power button should be pressed for more than 4 seconds before the system
powers down.
Hard Disk LED Connector (HD_LED)
The connector connects to the case's IDE indicator LED indicating the activity status of
IDE hard disk. The connector has an orientation. If one way doesn't work, try the other
way.
Reset Switch (RESET)
The connector connects to the case's reset switch. Press the switch once, the system
resets.
