ATX12V Power Supply Connector & Power Switch (POWER SW)
The BA1 series mainboards prefer an ATX 12V power supply. Be sure to connect the
ATX 12V power supply plug to this connector in its proper orientation. The BA1 series
mainboards provide an unique design especially for those who still use ATX power
supply(w12V connector) as long as their ATX power supplies can provide enough
current on +12V rail(at least 8 Amperes).System stability with an ATX power supply is
not guaranteed and we are not responsible for any damage caused.
The power switch (POWER SW) should be connected to a momentary switch. When
powering up your system, first turn on the mechanical switch of the power supply (if one
is provided), then push once the power switch. When powering off the system, you
neednt turn off the mechanical switch, just
Push once
