ATX Power Connector
There are a 24-pin main power
supply connector(PW1:J1B4) and
a 4-pin CPU PWR connector (J32)
on the board. These power con-
nectors meet the SSI EPS 12V
specification. You can also use a
20-pin PWR supply; however, the
4-pin 12V PWR supply is required
to ensure sufficient power supply.
See the table on the right for pin
definitions. For CPU PWR (J1D1),
please refer to the item listed be-
low.
