Hardware installation 22 22
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 22
With the use of the power connector the power supply can supply enough stable power to all the com ponents 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 con nector mainly supplies power to the cpu if the 12v power connector is not connected the computer will not start 22

Be sure to connect fan cables to the fan headers to prevent your cpu and system from over 23
Contact the place of purchase or local dealer if you are not able to replace the battery by your 23
Headers 23
Heating overheating may result in damage to the cpu or the system may hang 23
Of the battery the positive side should face up 23
Self or uncertain about the battery model 23
The battery provides power to keep the values such as bios configurations date and time information in the cmos when the computer is turned off replace the battery when the battery voltage drops to a low level or the cmos values may not be accurate or may be lost 23
The motherboard has a 4 pin cpu fan header cpu_fan a 4 pin sys_fan1 and a 3 pin sys_ fan2 system fan headers and a 3 pin power fan header pwr_fan most fan headers possess a foolproof insertion design when connecting a fan cable be sure to connect it in the correct orientation the black connector wire is the ground wire the motherboard supports cpu fan speed control which requires the use of a cpu fan with fan speed control design for optimum heat dissipation it is recom mended that a system fan be installed inside the chassis 23
These fan headers are not configuration jumper blocks do not place a jumper cap on the 23
Used batteries must be handled in accordance with local environmental regulations 23
When installing the battery note the orientation of the positive side and the negative side 23

Front panel audio module refer to the instructions on how to activate ac 97 functionality via the audio software in chapter 5 configuring 2 4 5 7 channel audio 26
Hardware installation 26 26
Instead of a single plug for information about connecting the front panel audio module that has different wire assignments please contact the chassis manufacturer 26
Ously if you want to mute the back panel audio only supported when using an hd front panel audio module refer to chapter 5 configuring 2 4 5 7 channel audio 26
Some chassis provide a front panel audio module that has separated connectors on each wire 26
The front panel audio header supports hd audio by default if your chassis provides an ac 97 26
The front panel audio header supports intel high definition audio hd and ac 97 audio you may connect your chassis front panel audio module to this header make sure the wire assignments of the module con nector match the pin assignments of the motherboard header incorrect connection between the module connector and the motherboard header will make the device unable to work or even damage it 26
You may connect the audio cable that came with your optical drive to the header 26
