Novice Learn the three graphics installation board

The motherboard is a very important device in the computer, it is the basic platform of all other accessories. Therefore, we first to understand the board of the motherboard, I hope more readers will be able to understand the motherboard, understand the motherboard on the premise of installing a motherboard.

First, understand the board type

We often say that the motherboard board type, refers to the motherboard on the layout of the components of the arrangement. You may find it strange that this article is not about how to install the motherboard? How to pull on the board of the motherboard type? Because different motherboard board types may require different chassis, power supplies, and so on. So it is necessary to understand the common motherboard board types, mainly: At, Baby at, ATX, Micro ATX, Flex ATX and other structures.

1. At structure (as shown in Figure 1)

At is the most basic type of board, which is generally used on motherboards prior to 586. At the motherboard size is larger, the board can be placed more components and expansion slots. It is a straight design with a keyboard socket on the edge, with 8 I/O expansion slots on the upper left of the motherboard. However, some peripheral interfaces (such as: serial port, parallel port, etc.) need to be connected with the cable and then installed on the chassis, a large number of cables caused the internal structure of the computer complex, confusion, unreasonable layout.

2. Baby at structure (as shown in Figure 2)

Baby at Motherboard is an improved type at motherboard that is slightly longer than the at motherboard and is considerably narrower than the at motherboard. Baby at the motherboard after the I/O expansion slot at the motherboard, keyboard sockets and other peripherals and components placed in place, and the memory slot and other internal components of the structure of the contraction, coupled with large scale integrated circuit to reduce the internal components, so baby at the motherboard than at the motherboard layout more reasonable. However, when installing PCI or ISA long cards, due to the CPU and CPU heatsink block, it is easy to install the situation is not in place. Baby at motherboards, which are typically built with two 6-pin connectors and 20-pin power connectors, can use the at or ATX power supplies.

3. ATX structure (as shown in Figure 3)

ATX is the most common motherboard structure, which rotates 90 degrees counterclockwise on baby at, which makes the motherboard's long edge close to the rear of the chassis and the peripheral interface can be integrated directly into the motherboard. The ATX structure has a standard I/O panel socket that provides two serial ports, a parallel port, an PS/2 mouse interface, and a PS/2 keyboard interface of 159mmx44.5mm size. These I/O interface signals directly from the motherboard, the cancellation of the connection cable, so that the motherboard can be integrated more functions, but also eliminates the electromagnetic radiation, contention space and other drawbacks, further improve the stability and maintainability of the system. In addition, in the motherboard design, because of wide width, the memory slot can be close to the rightmost I/O slot design, CPU slots are also designed in the memory slot on the right or the lower part of the I/O slot on the full length of the card is no longer limited, the memory of the replacement is more convenient Floppy interface and hard disk interface arrangement position, but also let you save data cable, easy to install.

4. MICRO ATX Structure (as shown in Figure 4)

The Micro ATX is also called the mini ATX structure, which is a simplified version of the ATX structure. The main purpose of the Micro ATX specification is to reduce the overall cost of the PC system and to reduce the power requirements of the computer system. The main features of the Micro ATX architecture are smaller motherboard sizes, smaller power supplies, and lower motherboard and power supply dimensions that directly reflect the cost of the computer system. While reducing the size of the motherboard can reduce costs, the number of I/O expansion slots available on the motherboard is relatively reduced, and the Micro ATX supports up to four expansion slots, which can be a combination of various specifications, such as ISA, PCI, or AGP, depending on the motherboard manufacturer.

5. Flex ATX Architecture (as shown in Figure 5)

Flex ATX Also known as the WTX structure, it is the latest developed by Intel, the introduction of All-in-one integrated design ideas, so that the structure of simple refining, reasonable design. The biggest benefit of the Flex ATX Architecture is that it is about one-third smaller than the Micro ATX motherboard area, making the chassis more compact to layout.
