2.Line up your motherboard with the standoff holes, and determine which ones line up and remember where they are. Not all motherboards will match with all of the provided screw holes, and this is not necessary for proper functionality. (In other words there will likely be extra holes.) Some standoffs may be pre-installed for your convenience.

3.Lift up and remove your motherboard.

4.Screw in the brass standoffs to the threaded holes that line up with your motherboard’s mounting holes.

5.Place your motherboard on the brass standoffs.

6.Mount your motherboard on the standoffs with the provided Phillips-head screws. Your moth- erboard is now installed.

POWER/LED CONNECTIONS

The power supply is an ATX12V form factor power supply. It has a single 24-pin Main Power Connector, and a 4-pin +12V Power Connector for the motherboard. It is backwards compatible to previous ATX form factor power supplies. If your motherboard does not support the +12V 4-pin Power Connector, you can still use this power supply. It also comes with three 4-pin Peripheral Power Connectors, one SATA Power Connector and one 4-pin Floppy Drive Power Connector for your drives.

1.Connect the 24-pin ATX power connector (and +12V connectors if appropriate) to your motherboard. If your motherboard uses a 20-pin connector; detach the 4-pin attachment on

24-pin power connector (see picture 1 and 2).

2.Power LED (labeled POWER LED) connector is located behind the Reset connector.

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

4. Hard Drive LED (labeled H.D.D. LED) connects to the IDE connector.

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 which is keyed so that it can’t be accidentally reversed as long as it is 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.

Note: Please check your motherboard manual for your USB header pin layout and make sure it matches the attached table. If it does not match this Intel standard, please call Antec customer support at (800) 22ANTEC (North America) or at +31 (0) 10 462-2060 (Europe) to buy a USB adapter. This adapter will allow you to connect the front USB to your motherboard on a pin-by-pin basis.
