(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.
