Single USB 2.0 connector (5-1 pin)

This connector is for a USB 2.0 port. Connect the USB module cable

to this connector, then install the module to a slot opening at the back

of the system chassis. This USB connector complies with USB 2.0

specifications and supports up to 480Mbps connection speed.

6. ATX power connectors (24-pin EATXPWR, 8-pin EATX12V, 4-pin EATX12V)

These connectors are for ATX power supply

plugs. The power supply plugs are designed to fit

these connectors in only one orientation. Find the

proper orientation and push down firmly until the

connectors completely fit.

•

For a fully configured system, we recommend that you use a power supply unit

(PSU) that complies with ATX 12 V Specification 2.0 (or later version) and provides a

minimum power of 350 W.

•

DO NOT forget to connect the 4-pin/8-pin ATX +12V power plug. Otherwise, the

system will not boot up.

•

We recommend that you use a PSU with higher power output when configuring a

system with more power-consuming devices or when you intend to install additional

devices. The system may become unstable or may not boot up if the power is

inadequate.

•

If you are uncertain about the minimum power supply requirement for your system,

refer to the Recommended Power Supply Wattage Calculator at http://support.asus.

Speaker connector (4-pin SPEAKER)

The 4-pin connector is for the chassis-mounted system warning speaker.

The speaker allows you hear system beeps and warnings.
