2-6 Connectors, Headers

1. Power Connector: AT Power Connector (12-pin block): ATPWR1
This connector connects to a standard AT power supply. To connect the leads from the
power supply, ensure first that the power supply is not plugged. Most power supplies
provide two plugs (P8 and P9), each containing six wires, two of which are black. Orient
the connectors so that the black wires are located in the middle.
Using a slight angle, align the plastic guide pins on the lead to their receptacles on the
connector. Once aligned, press the lead onto the connector until the lead locks into place.
2. Power Connector: ATX Power Connector (20-pin block): ATXPWR1
ATX Power Supply connector. This is a new defined 20-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.
* Please don't turn off / on power supply too quickly. We recommend at least wait 4sec
before turn on the power , to protect the system.
