Antec III 500 Installing The Motherboard, Connecting The Usb Ports, Connecting the Power and LED

INSTALLING THE MOTHERBOARD

This manual does not cover CPU, RAM, or expansion card installation. Please consult your motherboard manual for specific mounting instructions and troubleshooting.

1.Lay the case down, with the open side facing up. The drive cages and power supply should be visible.

2.Make sure you have the correct I/O panel for your motherboard. If the panel provided with the case isn’t suitable, please contact your motherboard manufacturer for the correct I/O panel.

3.Line up your motherboard with the standoff holes, and remember which holes are lined up. Not all motherboards will match with all the provided holes; this is normal, and won’t affect functionally. (In other words, there will likely be extra holes.)

4.Remove your motherboard by lifting it up.

5.Screw the brass standoffs into the threaded holes that line up with your motherboard. Do not over-tighten the standoffs. Some standoffs may be pre-installed for your convenience.

6.Place your motherboard on the brass standoffs.

7.Screw in your motherboard to the standoffs with the provided Philips-head screws. Your motherboard is now installed.

Connecting the Power and LED

If the motherboard has a 20-pin power receptacle, detach the 4-pin attachment on the 24-pin power connector, see pictures 1 and 2. Before you connect the power supply to any of the devices, please consult the appropriate user manuals for the motherboard and other peripherals.

1. Connect the 24-pin Main Power Connector and

the 4-pin or 8-pin 12V connector to the motherboard	Picture 1	Picture 2
as needed. If the motherboard uses a 20-pin
connector, detach the 4-pin attachment on the
24-pin power connector (see pictures 1 and 2).
Note: the detachable 4-pin section cannot be	For 24-pin	For 20-pin

2.Connect the Reset switch (labeled RESET SW) to

the motherboard at the RST connector. Polarity (positive and negative) does not matter for switches.

3.The Power Switch (labeled POWER SW) connects to the PWR connector on the motherboard.

4.The Power LED (labeled POWER LED) connector is located behind the Reset connector. For LEDs, colored wires are positive (+). White or black wires are negative (–). If the LED does not light up when the system is powered on, try reversing the connection. For more info on connecting LEDs to your motherboard, see your motherboard manual.

5.The Hard Drive LED (labeled HDD LED) connects to the hard drive activity header.

CONNECTING THE USB PORTS

You will find a single 10-pin connector on a cable attached to the front USB ports. This is an Intel standard connector that is keyed so that it can’t be accidentally reversed when connected to a proper Intel® standard motherboard header. Connect the 10-pin connector to your motherboard headers so that the blocked pin fits over the missing header pin.
