(1). ATX1: ATX Power Input Connector

Attach the connector from the power supply to the ATX1 connector here. Remember you have to push the connector from the ATX power supply firmly to the end with the ATX1 connector, insuring that you have a good connection.

Note: Watch the pin position and the orientation.

Caution

If the power supply connectors are not properly attached to the ATX power supply, the power supply or add-on cards may be damaged.

One end of AC power core connects to ATX power supply, and the other end (AC plug) will plug into the wall outlet. Be aware that when facing the wall outlet, the round hole is in the middle. The right side slot is called ground wire slot. It has a longer slot length than the left side slot. The left side slot is called the live wire slot. You can use an electroscope to detect its polarity or you can use a voltage meter to measure the voltage of both slot sides. If you insert an electroscope into the live wire slot, the electroscope will light up. Using a voltage meter, you will find that the live wire slot will register a higher voltage.

If you reverse the polarity of AC plug, it may affect the life of computer equipment, or cause an electric shock when you touch the computer chassis. We suggest that you plug the computer AC plug to a three-hole wall outlet for better safety and to avoid electric shock.
