How to Connect Power Button to Motherboard

Looking for how to connect power button to motherboard? The “System Power” button on a motherboard is a convenient way to turn on the system. It is a fairly common feature, but sometimes you may need to connect it to a power supply yourself to make it work.

In this article, I will show you how to connect the System Power button to a motherboard and a power supply. Here is everything you will read in this article:

How To Connect Power Button to Motherboard?

Before you can connect power button to motherboard, you need to first know how to locate the terminal on your motherboard. Here is how to locate terminals on the motherboards.

How To Locate Terminals On The Motherboard

Take a closer look at your motherboard and you’ll find two main power-based terminals at the back end: a 24-pin and 8-pin terminal, which acts as the main link between the power supply and the motherboard.

Using an 8-pin connection is important to allow your motherboard process power. If you don’t correctly connect the 8-pin connection to the main power supply and your PC attempts to use more power than it needs, it can cause damage to the motherboard.

While all industry-standard computer uses the same type of power connectors, it is important to know that the terminal position of each motherboard may be different based on the manufacturer. But the terminal should be easy for you to locate.

Connecting your computer’s power switches with the motherboard makes it easy to turn the entire system off or on.

Difference Between 8-Pin and 24-Pin Terminals

24-Pin Terminal

The 24-pin terminal is a common connection found in desktop computer motherboards. Older models used 20-pin terminals. The additional four pins allow the motherboard to power all internal components and have since become a standard across all major motherboard manufacturers.

While it is worth noting that a 24-pin terminal can function on an older 20-pin motherboard, there are no guarantees it will work perfectly on new generation motherboard.

8-Pin Terminal

Moving on, the 8-pin terminal is what connects the supply power to the motherboard. The 8-pin terminal can be found on the Front Panel Header of the motherboard.

The computer is reliant on it being connected to start up. So, in short, connecting the power button to the motherboard involves connecting the power cord to the 8-pin socket.

Steps To Connect The Power Button To The 8-Pin Socket

Locate 8-Pin Terminal?

The Front Panel Header (FPH) is where the 8-pin terminal that transfers current from the power button to the motherboard is located.

It’s important for booting up your Operating System and initializing other crucial computer systems. The FPH is usually easy to locate as it is labeled ‘Front Panel Header’ or ‘F_Panel’ on most motherboards.

Get Ready To Connect

Please be informed that the F_Panel is equipped with a power button jumper that turns on and off the power supply of your motherboard. Right before connecting the cable, ensure that the power outlet is switched off to prevent electrocution.

Besides, there are some connection pins on the F_Panel that are used for other components and functions; therefore, you should make sure to connect to the right pins by referring to the specification or manual of your motherboard.

Connect The Power Button Jumper To The 8-Pin Terminal

To power on the motherboard and components of your custom-built PC system, you need to connect the Power Switch jumper to the Power Switch pins on the Front Panel Header.

This is a pretty easy job, but please make sure you move the jumper only after ensuring that your PC’s case is turned off and your current workstation off as well. The Power Switch pins are located next to the Power LED pin within the Tristate Header on the motherboard so locating these two pins should not be difficult.

Does the Polarity (+/-) Matter When Connecting the Jumper to The Pins

When connecting a jumper to a motherboard, there is no need to worry about the polarity of the jumper or any pins for that matter. You can connect it on any two pins as long as you complete the circuit and power gets from one pin to another. With a jumper, the polarity does not matter.

However, for LED lights on a hard disk or power supply unit, polarity matters in that you need to make sure that the negative jumper is connected in the negative pin and the positive jumper is connected in the positive pin.

Close The Computer And Press The Power Button

To ensure your motherboard uses the power button correctly, once you’ve assembled it and made the necessary connections, close up the CPU to prevent any external damage to it or the other parts in your computer.

Once that’s done, switch on your power outlet and press the power button to see whether or not everything works perfectly.

PC Doesn’t Turn On After Connecting The Jumper Cable

Sometimes, people experience PC not turning on after connecting the jumper button. If your PC refuses to turn on, you may want to check the following:

  • Check the 24-pin ATX connector to see that it is correctly connected to the motherboard.
  • Check that the 8-pin connector is correctly and tightly connected to your motherboard from PSU.
  • Check the power switch jumper to ensure it is not damaged.
  • Check the power switch pin on the FHP to ensure they are not damaged.

How To Turn On The motherboard Without A Power Button

Turning on the computer without a power button is not such a hard thing to do. However, you need to have some technical knowledge of the motherboard and the power switch location to get this done.

Some motherboards have stickers that point to the location of the pins. To make this easier for you, locate the power switch section. You can attach the power button, power LED, reset button and Hard Disk LED with these pins.

To power up your computer with a working power button connects two pins and signals the motherboard to power on the computer. By following the same procedure, you can turn your computer on without pressing any power button.

Just locate the two pins for the power button from the pins on your motherboard’s F_Panel. Use a test pin or a metal surface, such as a screwdriver to touch the two pins to power on your computer without pressing any button.

Conclusion

If you want to start building your computer, connecting the Power Button is a good place to start. There’s no need to be intimidated by it, as long as you know how your Front Panel works and uses the signal from your Power Button correctly.

Make sure you’re familiar with your power supply unit (PSU) and your Front Panel before working on a PC. A few minutes of research are time well spent and will ensure that you don’t make mistakes during installation, like me. If you find this guide helpful, share it with your friends
