(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 80W 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 6.6A on +12V and the power supply unit has a minimum power rating of 80W. The system may become unstable or may not boot up if the power is inadequate.
