1/2) ATX_12V/ATX (2x2 12V Power Connector and 2x12 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.
3/4) CPU_FAN/SYS_FAN (Fan Headers)  All fan headers on this motherboard are 4-pin. Most fan headers possess \
a foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orient\
ation (the black connector wire is the ground wire). The speed control function requires the use of a fan with fan speed control design. For optimum heat dissipation, it is recommended that a system fan be install\
ed inside the chassis.
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.

Chapter 2 BIOS Setup
2-1 Startup ScreenThe following startup Logo screen will appear when the computer boots.(Sample BIOS Version: F3a)
Function Keys
 •When the system is not stable as usual, select the Load Optimized Defaults item to set your system to its defaults. •The BIOS Setup menus described in this chapter are for reference only an\
d may differ by BIOS version.
On the main menu of the BIOS Setup program, press arrow keys to move amo\
ng the items and press  to accept or enter a sub-menu. Or you can use your mouse to select the i\
tem you want.
 •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 n\
eed 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.)
BIOS (Basic Input and Output System) records hardware parameters of th\
e 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  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 wi\
thout 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.
