Computer assembly, how to plug in the chassis control cable?

Various control lines and indicator lines. The markings and their meanings on the signal cable plug provided on the chassis are as follows:

SPEAKER: PC speaker POWER SW: Power switch RESET SW: Reset button H.D.

D LED: Hard disk indicator POWER LED : The power indicator light finds the socket corresponding to the above control signal line on the motherboard (usually they are arranged centrally on the edge of the motherboard and marked with the corresponding name), and insert the signal line plugs into the corresponding pins. Note that the speaker wire, power switch wire and reset button wire have no positive and negative poles, but the hard drive indicator light and power indicator light must distinguish between positive and negative poles. Usually the white wire is the negative pole and the red wire is the positive pole. Be careful not to connect the USB cable backwards, check the missing pin position before inserting it

How to connect the computer?

1. First, connect the system power indicator light (PWR.LED 2pin) to the system power indicator light. If your computer is running normally, this light should be green and will continue to light up. ;When the computer enters sleep mode, interactive flashing will occur at this time.

2. If it is a hard disk indicator light (HDD.LED 2pin): Generally speaking, the LED is red. If the light is on, it means that the hard disk operation is in progress.

3. ATX power switch/soft boot function pin header (PWRBTN 2pin): This set of pin headers is connected to the main switch on the computer host panel that controls the computer power supply.

4. Reset button pin header (RESET 2pin): This needs to be connected to the Reset reset switch on the panel.

How to wire desktop computers correctly

1. Power switch connection cable

When you connect the power switch cable, generally speaking, you will connect it from the chassis panel Find the two-pin plug marked "power sw". At this time, you can see that it is divided into two colors: white and brown, and then plug it into the pin on the motherboard marked "pwr sw" or "PWR". That's it.

2. Reset switch connection cable

This switch is used to hot-start the computer. When connecting, you must first find the two-pin plug marked "RESET SW". There are also two colors, white and blue. Then you only need to plug this wire into the pin marked "Reset sw" or "RST" on the motherboard and you are done.

3. Power indicator light connection cable

At this time, you need to first find the three-pin plug marked "Power LED". Pay attention here to the middle line. One line is empty and two are missing. The terminals are distinguished by white and green colors, and then plug it into the pin marked "PWR LED" or "P LED" on the motherboard.

4. Hard drive indicator light connection cable

When connecting the hard drive indicator light, you must first find the two-end plug marked "H.D.D.LED", and also make sure their colors are clear, so that They can be plugged into the motherboard pins labeled "HDD LED" or "IED LED".

5. Speaker connection cable

For the speaker, you need to find the four-pin plug of "SPEAKER" first, and its middle two wires are blank. Just plug it into the motherboard marked with Just put "SPEAKER" or "SPK" on the pin. When plugging, pay attention to the red plug for the positive pole and the black plug for the negative pole.

Summary: This is the introduction to the method of connecting computer cables and how to correctly connect desktop computers. The method must be mastered when connecting computer cables, so that they will not be connected to the wrong position, and at the same time, when connecting When connecting, the respective colors must also be clarified, so that is the correct way to connect them.

How to connect computer cables?

How to connect the computer host?

The steps for connecting the computer host are as follows: Connect the power cord. Plug one end of the power cord into the power socket corresponding to the computer host, and the other end into the power socket. Connect the motherboard power supply interface. At present, most motherboards have 24PIN interfaces, and power supplies also have 24PIN interfaces, which can be plugged in accordingly. This connection method has a fool-proof design, so it is generally unlikely to be plugged in incorrectly. Connect the CPU power supply interface. Just connect the installed CPU power supply 4PIN interface to the corresponding slot position. Connect the hard drive power supply interface. The hard disk power supply is also a 4PIN interface, and the power interface only needs to be connected to the hard disk interface. Connect the independent graphics card power supply interface (optional). If there is an independent graphics card installed in the computer, generally the better independent graphics cards require a separate power supply, while the poorer independent graphics cards are powered by the motherboard where the motherboard is inserted. Generally, the graphics card interface that requires separate power supply is also 4PIN, similar to the CPU power supply interface. Connect the motherboard jumpers. The motherboard jumper is a very troublesome problem for many novice friends when installing a computer. It mainly involves the connection of the power supply chassis power button, restart button, and chassis power indicator lines. In the wiring between the motherboard and the chassis, the switch and restart are not divided into positive and negative levels, as long as they are plugged in the right position. Following the above steps, the connection to the computer host is completed.

How to use connected headphones on the computer?
