(1) Power Connector (24-pin block) : ATXPWR
ATX Power Supply connector.
This is a new defined 24-pins connector that usually
comes with ATX case. The ATX Power Supply allows to use 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.
