(1) Power Connector (24-pin block): ATXPWR1
ATX Power Supply connector: This is a new defined 24-pins connector that
usually comes with ATX case. The ATX Power Supply allows using soft power
on momentary switch that connect from the front panel switch to 2-pins Power
On jumper pole on the motherboard. When the power switch on the back of the
ATX power supply turned on, the full power will not come into the system board
until the front panel switch is momentarily pressed. Press this switch again will
turn off the power to the system board.
** We recommend that you use an ATX 12V Specification 2.0-compliant power
supply unit (PSU) with a minimum of 350W power rating. This type has 24-pin
and 4-pin power plugs.
** If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the
20-pin power plug can provide at least 15A on +12V and the power supply unit
has a minimum power rating of 350W. The system may become unstable or may
not boot up if the power is inadequate.
** If you are using a 20-pin power plug, please refer to Figure1 for power supply
connection. Power plug form power supply and power connectors from
motherboard both adopt key design to avoid mistake installation. You can insert
the power plug into the connector with ease only in the right direction. If the
direction is wrong it is hard to fit in and if you make the connection by force if is
possible.
