Power On/Off: PWRBT
Connect your power switch to this header (momentary switch type).
To turn off the system, press this switch and hold down for longer than 4 seconds.
ATX 12V Power Supply:ATX PW
Attach theATX 12V Power cable to threeconnector. (This motherboard requires anATX 12V power supply, anAT andATX
power supply can NOTbe used.)
When using the Power-On by PS/2 Keyboard function, please makesure theATX power supply is able to provide at least
720mAon the 5V Standby lead (5VSB).
PS. Power supply must be useATX 12V specification.
Anew superset of the originalATX power supply is now defined. Named “ATX 12V,” this new power
supply is comprised of a standardATX unit plus the following enhancements:
ꢂ
ꢂ
Increased +12 VDC output capability. Mother board components with unique voltage
requirements are increasingly expected to be powered via DC/DC converters off the +12 VDC
power supply output. This trend is due primarily to the higher power conversion and transmission
efficiencies of +12 VDC relative to +5 VDC or +3.3 VDC.ATX12V power supplies should be
designed to accommodate these increased +12 VDC current requirements and to address
associated issues such as cross-regulation, capacitive loading, transient surge tolerance, cable
voltage drop, and cooling.
New +12 V power connector. To enable the delivery of more +12 VDC current to the
motherboard, a new 4-pin receptacle/header combination--the + 12 V power connector–has
been defined. The presence of the +12 V power connector indicates that a power supply
isATX12V; the absence of the +12 V power connector indicates that a supply isATX.
CMOS Clear (JP5)
In some cases the CMOS memory may contain wrong data, follow the steps below to clear the CMOS
memory.
1. Clear the CMOS memory by momentarily shorting pin 2-3 on jumper JP5. Its white colored cap
can easily identify this jumper.
2. Then put the jumper back to 1-2 to allow writing of new data into the CMOS memory.
