Computer interface is designed to prevent the stay, as long as the connection in accordance with the color, interface shape connection can be quickly completed. Don't worry about the wrong interface, because the shapes of different interfaces are completely different.

　2 Connection Monitor

The following is the connection step for the monitor.

Step 1. Insert the monitor signal cable into the external interface of the video card The monitor's interface is divided into VGA and DVI two kinds, in connection with the graphics interface need attention.

VGA connector, insert the corresponding VGA connector on the video card

Step 2 Tighten the nut on the signal line and fix it. Although the data line has been plugged in, but still need to tighten the nut so that it will not loose.

Tighten the two nuts in the place.

Step 3 Plug the monitor power cable into the monitor's front two steps to connect the monitor's data cable, and finally plug the Monitor's power cord into it.

Monitor power connector

Connect the monitor only need to pay attention to two points: one is to distinguish between VGA and DVI interface, should be connected with the corresponding interface; second, after the interface connection, remember to tighten the signal line of the nut, so as not to loosen the cause of the fault.

Step 3 Keyboard Mouse connection

The keyboard and mouse connections are simple. The keyboard on the back of the motherboard, mouse jack color is different, according to the keyboard or mouse plug color inserted into the corresponding jack can be.

Insert keyboard and mouse plugs

The keyboard mouse interface type is the same as the PS2 interface. Colors are the way to differentiate them, the keyboard interface is purple, and the mouse interface is green.

　Step 4 Speaker Connection

At present, the use of more speakers are 2.1-channel structure of the speakers, the following explanation of the specific connection operation of the speaker.

Insert the signal line of the satellite speaker into the Jack

When connecting the satellite speaker signal line, pay attention to distinguish between left and right

Insert an audio line into

When inserting, notice the color of the plug should correspond

Locate the audio output hole

Audio output hole

Insert output jack

Be sure to insert the speaker plug completely into the jack

　Step 5 Chassis Power connection

The following explains the connection method of the chassis power supply.

Identify the direction of the power supply socket

Plug the power cord into the outlet of the power supply
