Detailed wiring diagram of Computer Installation

Graphic DIY interface cable installation details 1. Understanding the detailed installation process of the main board power supply interface Diagram

On the motherboard, we can see a rectangular slot, which is the power supply slot (such as) for the motherboard ). Currently, there are two main types of motherboard Power Supply interfaces: 24-pin and 20-pin. On the mid-to-high-end motherboard, the 24-pin power supply interface is generally used. The low-end products are generally 20-pin. The insertion method is the same regardless of the 24pin and 20pin.

24-pin interface for power supply to the motherboard

The interface for power supply to the motherboard adopts a stay-proof design. Only the correct method can be used for insertion. After careful observation, we will find that there is a raised slot on the interface of the motherboard power supply, and a snap-in design is also used on the power supply interface, one advantage of this design is to prevent the user from unplugging. On the other hand, the two interfaces can be installed together more firmly.

Ii. Understanding detailed installation process of CPU power supply interface Diagram

To provide higher and more stable voltage to the CPU, the Main Board currently provides an interface for separate CPU power supply (Four, six, and eight), such:

12 V four-pin power supply interface provided on the motherboard for separate CPU power supply

4-pin, 6-pin, and 8-pin interfaces for CPU power supply

The installation method is also quite simple. The interface is the same as the slot that supplies power to the motherboard. It also uses a foolproof design, so that we can install it easily.

3. Understanding how to install SATA serial port

Due to higher transmission speed, Sata serial ports gradually replace PATA and become the mainstream. At present, most hard disks adopt serial ports. Due to the more rational design of SATA data lines, it provides more convenience for our installation. Next, let's take a look at the SATA interface on the motherboard.

The above two images are the SATA interfaces provided on the motherboard. Some may ask, the SATA ports on the two boards are not the same. After careful observation, we will find that in the figure below, a protective layer is designed around the SATA interface, which plays a very good role in protecting the interface, this design is generally used on a large-brand motherboard.

The installation of the SATA interface is also quite simple. The interface adopts a sticky-Proof Design and cannot be inserted in the reverse direction. Users can carefully observe the interface design to see how to connect. In addition, it should be noted that the power supply interface of the SATA hard disk is also different from the ordinary four-pin trapezoid Power Supply interface, which is the comparison between the SATA Power Supply interface and the ordinary four-pin trapezoid Power Supply interface.

4. Know how to install the parallel port of PATA

Ordinary four-pin trapezoid Power Supply

The PATA port does not disappear on the motherboard. Even if the port is not supported by the Intel 965 chipset, the motherboard manufacturer also provides an additional chip to support the port, this is because most of the current optical drives still use the PATA interface. I believe you are familiar with pata. For details, refer:

Two PATA interfaces on the motherboard

The installation method is also quite simple. Do you see a gap in the middle of the outside of the PATA interface? There is also a convex part in the middle of the side of the PATA data line, the two parts can be smoothly inserted only after they are correctly combined, and cannot be installed if the direction is reversed. It is also a foolproof design.

We can also see an interface like this on some motherboard, which is the same as the parallel port PATA interface, but is a little short. This is the data line interface of the soft drive, although there are not many users using the software drive, it can still be seen on some motherboard.

5. Understand the graphic Installation Process of the extended front USB interface on the motherboard

Currently, USB has become the most commonly used interface. Most of the Main Boards provide up to 8 USB interfaces, but generally only four interfaces are provided in the back panel, the remaining four must be installed on the USB interface in front of the chassis for ease of use. Currently, the front-end USB interface is provided on the motherboard. For details, see:

Is the front USB interface provided on the motherboard. For example, there are two groups of USB interfaces, each of which can be connected with two external USB interfaces: USB 4, 5, USB 6, and 7, in total, four USB interfaces can be expanded on the front panel of the chassis (of course, the chassis must be supported. In general, the chassis is only available for two sets of front-end USB interfaces, so we only need to pick up a group ).

It is the connection line of the front-panel USB of the chassis, where VCC is used for power supply, usb2-and USB + are the negative positive interface of USB, And Gnd is the ground. When connecting to the USB interface, you must refer to the motherboard manual for careful comparison. If the connection is improper, the motherboard may be burned out. Is the detailed connection method between the motherboard and the USB interface.

To facilitate user installation, the USB interface settings of many motherboard are quite user-friendly, such:

We can see that the USB interface is similar to the PATA interface design and adopts a sticky-proof design method. You can only insert the USB interface in the correct direction, incorrect direction is indeed inaccessible, greatly improving work efficiency and avoiding burning the motherboard due to incorrect connection method.

6. Understand the graphic Installation Process of the extended front-end audio interface on the motherboard

Today, the main board provides integrated audio chips, and the performance can fully meet the needs of most users, so we do not have to buy a sound card separately. In order to facilitate user use, most of the current chassis not only has the front USB interface, but also the audio interface is transplanted to the front panel of the chassis, to enable normal use of the headset and microphone on the front panel of the chassis, we should also correctly connect the front audio cable to the motherboard.

Is the extended audio interface. AAFP is the frontend audio interface that complies with ac97 sound effects, ADH is the extended audio interface that complies with Ada sound effects, and spdif_out is the coaxial audio interface. Here, we will introduce how to install the front-end audio connection (see ).

It is an extended plug-in connecting the front audio jack of the chassis to the motherboard. The front audio interface is generally dual-channel, L indicates the left audio channel, and r indicates the right audio channel. Mic is the front microphone interface, corresponding to the mic on the motherboard, The HPOUT-L is the left audio output, corresponding to the HP-L on the motherboard or line out-l (depending on the audio specifications used different, if the use of ADA sound specifications, then connected to the HP-L, the same below), HPOUT-R for the right channel output, corresponding to the motherboard on the HP-R or line out-R, according to the corresponding interface in turn access can be.

In addition, we will also find this interface on the motherboard, which is also the audio interface, but it corresponds to the audio interface on the back of the optical drive. In some power sources that support listening to music without boot, we can use the headphones on the front panel of the optical drive to listen to music after we connect to the audio cable. However, this function is not commonly used at present, most machines do not support this function, so you do not need to connect.

7. Understand the power supply and restart buttons of the chassis on the motherboard, and illustrate the Installation Method

Connecting power keys and restart keys on the chassis is the last step in computer installation. Many friends have a headache in power cord installation. Next, let's take the two mainboards as an example, describes how to install power keys and restart keys in detail.

One group of slots in the above two pictures is the slot for keys such as power supply and restart of the chassis.

(In general, red indicates the positive pole. If you are not sure about the installation, you can view the "+/-" pole ID on the back)

The above two figures show the power supply, restart, hard disk indicator, and front-end alarm horn interfaces of the chassis. For more information about how to install and install the motherboard slot, see.

Is the connection between the chassis and the motherboard power supply. Among them, pwr sw is the power interface, corresponding to the pwr sw interface on the motherboard, reset is the restart key interface, corresponding to the reset Jack on the motherboard, the above speaker is the front-end alarm horn interface of the chassis. We can see that it is a four-PIN structure. The line of the red line is the + 5 V power supply line, which corresponds to the + 5 V interface on the motherboard, the other three needles are easily inserted. Ide_led is the hard drive indicator on the chassis Panel. It corresponds to ide_led on the motherboard, and the remaining pled is the indicator on the computer. You can insert it to the motherboard. Note that the hard disk operating indicator light and power indicator light are divided into positive and negative. During installation, note that red represents the positive pole.

8. Know the radiator interface on the motherboard to introduce the installation process in detail

Many of my friends are not very clear about the radiator interface on the motherboard. Next I will introduce it in detail.

Cpu_fam in the above three pictures is the power interface of the CPU radiator. We can clearly see that the current CPU radiator interface adopts the four-Pin Design, which is obviously more than other radiators, this is because the main board provides the CPU temperature monitoring function, the fan can automatically adjust the speed according to the CPU temperature.

In addition, there are some cha_fam sockets on the motherboard, which are used to power the radiator. if you add a radiator, you can use these interfaces to power the fan. In addition, we can see that these interfaces all adopt a foolproof design method and cannot be inserted in the opposite direction. Therefore, you can take a closer look at the installation, which is very simple.

IX. Introduction to other interface installation methods

Expansion slot on the motherboard, where black is the PCI-E slot for installing PCI-E graphics card, PCI-E graphics card interface see

PCI-E interface for graphics card

On the motherboard of the earlier chipset, because PCI-E is not supported, it is still the traditional AGP 8x graphics interface, see the middle brown slot. The rest are PCI slots used to expand PCI devices.

The back of the new Motherboard chipset does not provide com interfaces. Therefore, a com slot is built into the motherboard. You can extend the support for com to make it easier for old users to use.

The PS/2 mouse and keyboard on the back of the motherboard, coaxial audio, e-SATA, USB, and 8-channel audio output interfaces.

Through the detailed introduction in this article, I believe that my friends have a deep understanding and understanding of the computer connection, so there are users who have been running on the machine recently, you may wish to follow the illustration process of the small series, do it yourself, experience DIY.
