How to connect motherboard and chassis?

The correct wiring method between the motherboard and the chassis is crucial for the normal operation of the computer. Properly connecting the motherboard and chassis can ensure the normal operation of hardware devices such as power supplies and fans, while avoiding computer malfunctions caused by incorrect wiring. In this article, PHP editor Strawberry will introduce you in detail the wiring method of the motherboard and chassis, helping you to correctly connect computer hardware devices and ensure the stable operation of the computer.

How to connect the motherboard and chassis?

The wiring method between the motherboard and the chassis is as follows: First, align the I/O interface slot on the back panel of the chassis with the I/O interface on the back of the motherboard, install the motherboard into the chassis, align it with the screw holes and secure it .

Then connect the power cord between the motherboard and the chassis, and connect the power pins on the motherboard to the plug on the chassis power cord.

Next, connect the USB, audio and power button cables on the front panel of the case to the corresponding connectors on the motherboard.

Finally, connect other cables on the motherboard, such as hard drive data cables, fan power cables, etc. After ensuring that the connection is firm, close the side panel on the left side of the chassis and the wiring is completed.

How to connect the chassis to the motherboard?

Connecting the chassis and motherboard is one of the important steps in assembling a computer. The following is the general connection method:

1. Prepare the case and motherboard: Make sure you have selected a compatible case and motherboard and place them on a clean surface suitable for operation.

2. Install the I/O cover: There is usually a removable metal plate on the back of the chassis, called the I/O cover. Before installing the motherboard, you need to open the case and remove the I/O cover according to the I/O interface layout behind the motherboard and store it in a safe place.

3. Mounting brackets/screws: Look inside the case. There are usually some brackets or screw holes for fixing the motherboard. Determine which brackets/screws need to be installed based on the motherboard size and hole layout.

a. Generally, ATX motherboards require 9 brackets/screws, Micro-ATX requires 6, and Mini-ITX only requires 4.

b. Use the provided brackets/screws or your own brackets/screws, and insert them into the bottom of the chassis or the fixing holes. Make sure the brackets/screws line up with the motherboard's mounting holes.

4. Install the motherboard: Gently place the motherboard inside the case so that the brackets/screws pass through the corresponding mounting holes on the motherboard. Make sure the back of the motherboard is not in contact with the case.

5. Fix the motherboard: Use appropriate screws to fix the motherboard to the chassis. Make sure not to tighten the screws too tightly or too loosely to avoid damaging the motherboard.

6. Connect the front panel: According to the marks on the chassis and motherboard, connect the power button, USB interface, audio interface and other cables on the front panel of the chassis to the corresponding pins or connectors on the motherboard.

7. Connect power and data cables: Connect power cables, SATA data cables, fan cables, etc., and connect them to the corresponding interfaces on the motherboard and other hardware devices (such as hard drives, optical drives, and fans).

8. Double check: Make sure all connections are tight and no cables are caught between any moving parts.

After completing the above steps, the chassis and motherboard are successfully connected together. Note that the actual connection method may vary depending on your case and motherboard model, so refer to your case and motherboard's user manuals for detailed instructions before you begin.
