Installing The Power Supply; Connecting The Ports And Leds; Connecting The Usb Ports; Connecting The Esata Port - Antec Twelve Hundred User Manual

Installing the Power Supply

1. With the case upright, place the power supply
on the four silicone pads on the bottom of the
case.
Note: Power supplies with fans on the bottom
of the power supply will need to be mounted
so that the fan is facing the top of the case.
Twelve Hundred provides mounting holes for
power supplies with standard mounting layouts
to be installed upside up or upside down.
2. Push the power supply to the back of the case and align the mounting holes.
3. Attach the power supply to the case with the screws provided.

Connecting the Ports and LEDs

Note: Please refer to your motherboard manual for specific pin outs or location of
front panel connectors.
1. Connect the Reset switch (labeled RESET SW) to the motherboard at the RST
connector. Polarity (positive and negative) does not matter for switches.
2. Power Switch (labeled POWER SW) connects to the PWR connector on the
motherboard.
3. There is no Power LED in this case. Three illuminated case fans will turn on
when there is power to the computer.
4. Hard Drive LED (labeled H.D.D. LED) connects to the IDE 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.

Connecting the USB Ports

Connecting the eSATA Port

You will find a SATA connector on a cable attached to the front ports. This internal
SATA connector is designed to connect to a standard SATA connector on your
motherboard. This will allow high speed external hard disk enclosures such as the
Antec MX-1 to run at the same speeds as if the hard disk were installed inside the case.
