ATX 12V Power Supply: ATX PW
Attach the ATX 12V Power cable to three connector. (This motherboard requires an ATX 12V power supply, an
AT and ATX power supply can NOT be used.)
When using the Power-On by PS/2 Keyboard function, please make sure the ATX power supply is able to
provide at least 720mA on the 5V Standby lead (5VSB).
It is recommended that an Intel Pentium 4 processor-based PC be powered by at least a 250 watt ATX 12V
power supply.
PS. Power supply must be use ATX 12V specification.
A new superset of the original ATX power supply is now defined. Named “ATX 12V,” this new
power supply is comprised of a standard ATX unit plus the following enhancements:
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 is ATX12V; the absence of the +12 V power
connector indicates that a supply is ATX.

Configure Memory
Directly supports one SDR SDRAM channel, 64b wide, providing support max of
3 Double-Sided DIMMs with unbuffered PC133.
The largest memory capacity
possible is 3GB.
On this motherboard, DRAM speed can be set independent
from the CPU front side bus speed. Depending on the DRAM clock speed setting
in the BIOS setup.
