1/2) ATX_12V_2X4/ATX (2×4 12V Power Connector and 2×12 Main Power Connector)
With the use of the power connector, the power supply can supply enough stable power to all the components
on the motherboard. Before connecting the power connector, first make sure the power supply is turned
off and all devices are properly installed. The power connector possesses a foolproof design. Connect the
power supply cable to the power connector in the correct orientation.
The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected,
the computer will not start.
To meet expansion requirements, it is recommended that a power supply that can withstand high
power consumption be used (500W or greater). If a power supply is used that does not provide the
required power, the result can lead to an unstable or unbootable system.

BIOS Setup
— 31 —
BIOS (Basic Input and Output System) records hardware parameters of the system in the CMOS on the
motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system startup,
saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup program that allows
the user to modify basic system configuration settings or to activate certain system features.
When the power is turned off, the battery on the motherboard supplies the necessary power to the CMOS to
keep the configuration values in the CMOS.
To access the BIOS Setup program, press the <Delete> key during the POST when the power is turned on.
To upgrade the BIOS, use either the GIGABYTE Q-Flash or @BIOS utility.
•
• Q-Flash allows the user to quickly and easily upgrade or back up BIOS without entering the operating
system.
•
• @BIOS is a Windows-based utility that searches and downloads the latest version of BIOS from the Internet
and updates the BIOS.
For instructions on using the Q-Flash and @BIOS utilities, refer to Chapter 4, «BIOS Update Utilities.»
Chapter 2 BIOS Setup
•
• Because BIOS flashing is potentially risky, if you do not encounter problems using the current
version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS, do it with
caution. Inadequate BIOS flashing may result in system malfunction.
•
• It is recommended that you not alter the default settings (unless you need to) to prevent system
instability or other unexpected results. Inadequately altering the settings may result in system’s
failure to boot. If this occurs, try to clear the CMOS values and reset the board to default values.
(Refer to the «Load Optimized Defaults» section in this chapter or introductions of the battery/clear
CMOS jumper in Chapter 1 for how to clear the CMOS values.)

item is set to Disabled, the xHCI Mode below will be automatically set to Auto.
&
& xHCI Mode
Allows you to determine the operating mode for the xHCI controller in OS.

Smart Auto This mode is available only when the BIOS supports the xHCI controller in the pre-boot
environment. This mode is similar to Auto, but it adds the capability to route the ports
to xHCI or EHCI according to setting used in previous boots (for non-G3 boot) in the
pre-boot environment. This allows the use of USB 3.0 devices prior to OS boot. xHCI
controller enabling and rerouting should follow the steps in Auto, when previous boot
routs ports to EHCI. Note: This is the recommended mode when BIOS has xHCI pre-
boot support. (Default)

Auto
BIOS routes the sharable ports to EHCI controller. Then it uses ACPI protocols to
provide an option to enable the xHCI controller and reroute the sharable ports. Note:
This is the recommended mode when BIOS does NOT have xHCI pre-boot support.

Enabled AllsharedportsareeventuallyroutedtothexHCIcontrollerduringtheBIOSbootprocess.
If BIOS does not have pre-boot support for the xHCI controller, it should initially route
the sharable ports to the EHCI controller and then prior to OS boot it should route the
ports to xHCI controller. Note: OS has to provide support for the xHCI controller in this
mode. If the OS does not provide support, all sharable ports won’t work.

Disabled
The USB 3.0 ports are routed to the EHCI controller and the xHCI controller is turned
off. All USB 3.0 devices function as High Speed devices regardless of xHCI software
support/availability. If this item is set to Disabled, the HS Port #1/2/3/4 Switchable
and xHCI Streams items below will become unconfigurable.
&
& HS Port #1 Switchable~HS Port #4 Switchable

Enabled
Corresponding USB 3.0 port is routed to xHCI. The USB 3.0 device attached on this
port with Super-Speed capability is visible to xHCI controller. (Default)

Disabled
Corresponding USB 3.0 port is routed to EHCI. The USB 3.0 device attached on this
port with Super-Speed capability will function as High-Speed.
