Discussion on some problems of assembling host 2

After the motherboard is installed in the chassis, the following is the final power supply, the outer end of the chassis, hard drive cable, CPU heatsink line, motherboard power cord and other wiring issues:

(1) Read the user manual of the motherboard to understand the location of each connection and the relevant instructions.

(2) Generally according to the power cord interface and the shape of the socket can determine the majority of the connection.

Front panel connection issues:

From the motherboard user manual, locate the interface location for the front panel: These are the switches, reboots, and power lights that connect the chassis. The Power led+ (Power lamp positive), power led-(negative power supply), reset SW (restart key), Power SW (on the key), this plug and unplug, you must remember to follow the instructions to plug in.

　　　

Front usb Cable

Front usb, the first most easy to identify and install is the original USB3.0 interface , as long as the plug to the protruding part of the slot on the small notch, you can be inserted firmly. The reverse is not plugged in, so do not stick.

USB2.0 interface, the shape is slightly different, but you can see it is actually 9 needles, the lower right corner of the position of a needle so that the reverse is not plugged in, note oh.

In general, the hardware manufacturers are now the interface to testify the overall, and designed anti-stay operation. Such an interface is not easy to connect to wrong.

Front Audio wiring

The audio line is also 9 pin, but it is obvious that the arrangement and the USB are not connected, it is also reverse the words are not plugged in.

　　

Other connections in the previous paragraph

In addition to these, the motherboard also has some other similar pins of the interface, easy to cause misleading, such as speaker (that is, connecting the buzzer interface for fault judgment, but I do not like the sound, so generally do not install it ...) ）

Connection of power supply cable---motherboard power cord

now the mainstream power lines, are divided into two shares. The 20-pin +4-pin structure is done because some low-end motherboards actually require only 20-pin interfaces (which are basically very low-end ones), while the general mainstream is 24-pin, but in order to maintain commonality, so separate the 4 stitches behind, we just need to see if the motherboard is 24 or 20, Then decided not to put the 4-pin and to the 20-pin together, the power cord because directly into some side of the circle, only after the direction can be plugged in, so this also as long as the attention not to plug the good.

　　　　　　

Connection of the power supply cable---CPU power cable (auxiliary power cord) and CPU heatsink power supply (CPU fan power)

These two are introduced just because the two are usually next to the CPU, but not the same interface, and one is the power, the other is the power out. CPU fan is the first diagram below, generally written next to the Cpu_fan, because the above design slot channel, so do not worry about plug-in. CPU power, it is from the power cord, but the interface has two, the majority of the current is still mainly 4-pin, part of the high-end only to see the 8-pin CPU power supply port, as long as the interface plug, the card buckle card is OK, and the motherboard power supply is square + round mouth, also do not worry about plug

4-pin CPU-powered 8-pin CPU-powered graphics installation

The installation of the video card is relatively easy, generally speaking, the slot behind the chassis is sealed, and the method of sealing is two, one is to use a screw to fix a blank behind the back, the other is directly and the chassis of the iron plate, directly before and after pulling off the good, now the interface of the video card is relatively single, Basically are pci-e mainly , the old interface has almost eliminated the light. The first picture is the card slot, access is not very difficult, just remember to put the card above the gold finger protection shell removed, and then access to the interface, then tighten the screws OK.
The only thing that needs special attention is that today's mid-and high-end discrete graphics cards mostly need to be powered independently , and the power-supply interface is similar to the CPU's power supply interface, which is a square + circular interface with a snap buckle, typically 6-pin. After the card is fixed, connect the power cord. Video card installation is relatively simple, but if need to remove, then pay attention to need to move the upper right corner of the interface diagram of the clip, the video card is bouncing up a little, then pull.

Installing the hard drive and optical drive

whether it is a solid-state drive or a mechanical hard disk, now the interface is the same, are like the right side of the left side of the power supply, and these two interfaces are designed to be L-type, of course, is also to prevent the insertion of the wrong (now all the interfaces are more humane, Unlike the old IDE line is blurred) to connect the power port of the line from the computer's power above, we just find the length of the same line connected on the line.

Note the difference between 3.0 and 2.0 of the SATA cable interface,

SATA data interface of the line general motherboard of the box will be sent one or two. The answer is to connect to the motherboard of the SATA interface, one end to the hard disk, the only thing to note is that Some motherboards are not all interfaces are SATA3.0, so it is best to check the instructions, determine which is SATA3.0 (low-end motherboard is all SATA2.0, that there is no way), especially the SSD, if received SATA2.0, interface rate bandwidth will have bottlenecks.

　　

Connection of optical drive or recorder (power cable, data cable SATA)

The optical drive/recorder, like the hard disk interface, is now also SATA interface, but the optical drive is generally not so high, so SATA2.0 is enough. (The SATA3.0 can also be connected to the 3.0 interface)

　　

Other wiring, in addition to the above-mentioned line of the connection method, the installation may also encounter some other additional things, such as:

A. Chassis Cooling fan

Some of the chassis or their own additional purchase of cooling fan, if the chassis itself sent, then generally there is no adaptation problem, but if you want to purchase additional cooling fan, pay attention to whether the chassis has to reserve the corresponding size of the cooling hole to the fan. (Most of the fan will cause noise problems, so if it is not particularly high-end equipment, the temperature is not special, not recommended to install an additional cooling fan), and then the fan installed on the chassis side before installing a dust screen, and then the fan is installed behind the dust net, and this fan power cord, usually the old 4-pin ladder type interface, Now the power is still retained these lines, everyone from the power part of the line to find a bit. In addition, this old-fashioned power cord can be converted to and from the SATA power cord, which can be achieved with the conversion line below.

　　

　　　　

B. Card Reader

For some photographers, a convenient built-in card reader, compared to each time you plug and unplug a card reader is much more convenient, but in fact, the card reader installation method, and the front of the other USB interface is the same , its behind, but also the above mentioned USB2.0, USB3.0 and so on. The card reader has some chassis, but also can buy their own optical drive bit of the reader, but if the USB3.0 interface itself, it should be noted that the motherboard needs at least two native USB3.0 interface to meet the reader and the front USB3.0

　　

Fan governor

Some high-end chassis with a fan governor, of course, this can also be installed, but the cost is high, the effect is general, price is not very high. Most fan governors are loaded with a line between the CPU fan's power connector and the CPU fan line, and the other interface is the same as the normal interface, such as the 4-pin old power connector.

Recognize the I/O panel

Connected peripherals, the main interface name and so on are below, just about some common sense, these IO panel interface does not need to connect, has been integrated into the motherboard.

　　

　　

We normally need these wires:

(1) USB2.0 (2) USB3.0 (3) keyboard, mouse interface (4) Display output interface VGA, DVI or HDMI display, can be connected to three monitors (5) Audio part speaker (6) LAN port cable (7) S/PDIF Optical network card

Other Notes:

A.usb interface generally black is USB2.0, Blue is USB3.0, of course, this is only the industry regulation calibration, but there is no exception.

B.HDMI and DVI are display output interface, connect the monitor with, HDMI not to say, home TV those also have, DVI interface, explain more complex, we just need to know dvi-i compatible with dvi-d, but D can not be compatible with I, from the interface look can also distinguish clearly, Because the interface of D has only one horizontal line, and I have 4 additional pins, interested can Baidu a bit--DVI interface-Baidu Encyclopedia.

C. When the external display, the preferred or DVI or HDMI, which is not the difference between the VGA interface because it is an analog signal, and is already the old standard, so for the resolution of more than 1440x900 above the screen, a little sense of difficulty, clarity is indeed a difference. Of course, if your video card and monitor have a DP interface, the DP interface is a better choice.

D. In the audio interface, the green is the output, that is, to connect the headset, the speaker, the red is the input, that is, to connect the microphone. As for the other several interfaces, I believe that the people who can use them, also do not need me to introduce ...

E.lan Mouth is our network, desktop can buy USB wireless network card to achieve wireless Internet access, wireless is not a patent for mobile phones and notebooks, so if the wiring is more troublesome, the desktop can consider the purchase of wireless network card. But it's not as stable as wired, wired or wired.
