Connecting the power button to the motherboard is a crucial step in assembling a computer. The power button’s purpose is to start and shut down the system.
While it might seem like a simple task, it’s essential to do it correctly to ensure your computer functions properly. This guide will walk you through the process of showing you the motherboard power switch pins to set up the power button to the motherboard.
Now to start with let’s take a look at the materials needed:
- Computer case with a power button
- Motherboard
- Screwdriver
- User manuals for the motherboard and computer case (if available)

How to Connect Power Button to Motherboard?
Right, it’s time to start connecting the power switch to your motherboard how exciting!
Step 1: Identify the Power Button Header on the Motherboard
The power button on a computer case connects to the motherboard through a small set of pins called the power button header.
Locate this header on your motherboard; it is usually situated at the bottom right corner and labeled “PWR_SW” or something similar, see the below two screenshots of my motherboards showing the power pins on the motherboard.
If you are still struggling to find them you might need to refer to your motherboard’s user manual to find the exact location.
Step 2: Identify the Power Button Connector
Examine the power button cable also known as the power sw cable that comes from your computer case. The power sw cable terminates in a connector that needs to be plugged into the power button header on the motherboard.
The connector typically has two wires, but it may have a single wire with a connector at the end depending on the age of the case.
Step 3: Motherboard Power Switch Connector
The power button connector is not symmetrical, so it needs to be plugged in the correct way. Look for a small arrow or a “+” sign on the connector; this indicates the positive side.
Align the connector with the corresponding pins on the power button header, ensuring that the positive side matches the positive pin on the header.
Carefully plug the power button connector into the power button header. Apply gentle pressure until it clicks into place. Make sure it is securely attached to prevent any accidental disconnections.
If you do not plug it in correctly or the wrong way around you will know as your computer and motherboard will not power on, so you will need to swap the power sw cable the other way around.
Step 4: Motherboard Cable Management
Once the power button connector is attached, tidy up the cables to ensure proper airflow and aesthetics within the case. Use cable ties or Velcro straps to secure loose cables, preventing any interference with cooling components or obstructing the motherboard.
Step 5: Test The Power Button To Motherboard
Before fully assembling your computer, it’s a good idea to test the power button. Connect the power supply to the motherboard if you have not done so already and then briefly press the power button on the case.
Hopefully, your PC front panel power switch should be working if that’s where it’s located.
If everything is connected correctly, your computer should power on. If it doesn’t, double-check the connection and make sure the power button is correctly oriented.
Final Thoughts:
Connecting the power button to the motherboard is a fundamental step in building a computer. By following these step-by-step instructions, you can ensure a smooth and error-free assembly process. I hope the process went smoothly and you have now learned how to connect a power button to a motherboard.
