AT & ATX Power Supply Connectors
CN3 is a standard 12-pin AT-type or PS/2 type connector. Be
sure to attach the two connectors with the two black wires
next to each other, at the center. CN4 is a standard ATX-type
power connector. (The ATX power connector can
only
be
inserted the correct way.)
NOTE:
To prevent electrical spikes, make sure that the power
supply is not connected to an outlet when making or removing
connections. Power supplies contain power reserves which
can damage electrical components.
