[. . . ] You may use the 20-pin ATX power supply as you like. If you'd like to use the 20-pin ATX power supply, please plug your power supply along with pin 1 & pin 13. This power connector is used to provide power to the CPU. Make sure that all the connectors are connected to proper ATX power supplies to ensure stable operation of the mainboard. It provides a high-speed digital interconnection between the computer and its display device. To connect an LCD monitor, simply plug your monitor cable into the DVI-D connector, and make sure that the other end of the cable is properly connected to your monitor (refer to your monitor manual for more information. It is easy to differentiate between audio effects according to the color of audio jacks. Line-In (Blue) - Line In, is used for external CD player, tape-player or other audio devices. This connector supports IDE hard disk drives, optical disk drives and other IDE devices. If you install two IDE devices on the same cable, you must configure the drives separately to master / slave mode by setting jumpers. Each connector can connect to one Serial ATA device. Please do not fold the Serial ATA cable into 90-degree angle. Otherwise, data loss may occur during transmission. This connector is for electrical connection to the front panel switches and LEDs. The fan power connectors support system cooling fan with +12V. When connecting the wire to the connectors, always note that the red wire is the positive and should be connected to the +12V; the black wire is Ground and should be connected to GND. If the mainboard has a System Hardware Monitor chipset on-board, you must use a specially designed fan with speed sensor to take advantage of the CPU fan control. You can install Overclocking Center utility that will automatically control the CPU fan speed according to the actual CPU temperature. ⷠFan cooler set with 3 or 4 pins power connector are both available for CPUFAN The system will record this status and show a warning message on the screen. To clear the warning, you must enter the BIOS utility and clear the record. This connector, compliant with Intel® I/O Connectivity Design Guide, is ideal for connecting high-speed USB interface peripherals such as USB HDD, digital cameras, MP3 players, printers, modems and the like. This connector allows you to connect the front panel audio and is compliant with Intel® Front Panel I/O Connectivity Design Guide. [. . . ] Adjust PCI-E Frequency (MHz) This field allows you to select the PCIE frequency (in MHz). Spread Spectrum When the mainboard's clock generator pulses, the extreme values (spikes) of the pulses create EMI (Electromagnetic Interference). the Spread Spectrum function reduces the EMI generated by modulating the pulses so that the spikes of the pulses are reduced to flatter curves. If you do not have any EMI problem, leave the setting at Disabled for optimal system stability and performance. [. . . ]
