What Are Motherboard Standoffs?

Motherboard standoffs are a key part of the internal components of a computer. They are metal studs that connect the motherboard to your PC’s case. Without them, your computer wouldn’t function properly. In this post, we’ll cover what motherboard standoffs are, why they are important, and how they are used.

What Are Motherboard Standoffs? How Are They Used?

Today’s gaming computers contain an array of electronics and components that require careful assembly. The motherboard is one of the most important parts, as it contains all other components, such as the processor and RAM. When installing a new motherboard, it is important to secure it to the case properly. To do this, you use special screws called “Motherboard Standoffs.”

Motherboard standoffs are small metallic or plastic components that provide a secure way to mount your system’s motherboard. Although often seen as something trivial, these screws provide a solid foundation for your device’s vital parts; therefore, choosing the right type of standoff for each type of application could be advantageous for you in the long run. In this article, we’ll discuss motherboard standoffs and explain why they are used in computing systems.

Do I Need Motherboard Standoffs?

Yes, motherboard standoffs are necessary for operating a computer system, as they help provide proper space between the board and the case so that no short circuits occur. Aside from helping prevent electrical fires, Motherboard Standoffs also help keep your components secure and in place within the tower case. When building or upgrading a PC, it is typically recommended to use Motherboard Standoffs to ensure the motherboard fits firmly and there’s ample support for the components within your computer.

Do Motherboards Come With Standoffs?

Standoffs are essential for mounting the motherboard as they provide support and a secure fit when connecting the board to other components in a system. They’re usually made of steel or plastic, come in various lengths, and require an installed washer or nut to create a secure connection. Motherboards do not include standoffs, meaning you will need to purchase them separately. It is important to read your motherboard manual to know what standoffs are needed and make sure they are purchased accordingly.

Do PC Cases Come With Motherboard Standoffs?

Most PC cases come with standoffs, which makes the installation process much easier. The number of standoffs that come with a case will depend on the size and type of case you have. For instance, some mini ITX cases may only have two or three standoffs, while a full-sized tower case might include more than six. Refer to the manufacturer’s manual to find out how many are included in your specific case. You can purchase additional ones from an electronics store or online if there aren’t enough.

What Size Motherboard Standoffs Do I Need?

When purchasing Motherboard Standoffs, make sure you buy the right size for your specific system. The size of the screw will depend on the type of case and motherboard you have. Most cases and motherboards use M3 screws that measure 3mm in diameter; however, some require larger or smaller sizes such as #6-32.

How To Install Motherboard Standoffs

Installing your motherboard standoffs is essential when building or repairing a gaming pc. Be sure to install your motherboard standoffs correctly, though; if done incorrectly, there is the risk of damaging your motherboard beyond repair. To get it right and avoid expensive repair costs, take your time and follow the steps below!

1. Check The Size Of Your Motherboard 

Installing motherboard standoffs is vital to ensure that your PC’s motherboard tray correctly supports your motherboard and components. But before you start, the first step is to determine the size of your motherboard, as motherboard standoffs are typically designed for a specific motherboard type or size. The most common motherboard models are ATX, Micro-ATX, and Mini-ITX. Check out our post on Motherboard sizes if you’re not sure what kind you have. Make sure to measure the length and width of your motherboard accurately so that you select the correct size of motherboard standoffs for your setup — it’s always better to be safe than sorry!

2. Screw In The Standoffs

Installing motherboard standoffs is critical to getting your computer up and running. These unique screws ensure that the motherboard properly fits into the motherboard tray inside the chassis, creating an electrically insulated connection that prevents shorts and damage from vibration. Even if you’ve assembled systems before, it can’t hurt to double-check your motherboard standoff positions: these tiny screws need to be in the right spot for safety and compatibility with your other parts. The process isn’t hard, but it adds an extra layer of security to ensure everything’s done right when you finally fire up your shiny new system!

Determine the standoff locations by checking your motherboard user manual and gently screwing them into the motherboard using your fingers.

3. Mount Your Motherboard In The Case

The next step is to place the motherboard inside your case carefully. Be sure to line the standoffs up with the holes in the case.

4. Secure The Motherboard To The Case

Once the motherboard is in place, tighten the standoff down.


We have gone through a detailed explanation of what a motherboard standoff is and its crucial role in the protection, stability, and longevity of your computer. It is fundamental for your motherboard to be correctly mounted to ensure it can uphold all of the tasks you’ll use it for. With all said and done, we can add motherboard standoffs to the ever-growing list of tiny yet critical components that make up your gaming PC. Their importance should not be underestimated, as they are responsible for maintaining all the other pieces in place and ensuring they are ready to take on whatever tasks you throw at them. So be sure to equip your setup with the right size and type of standoff, so your build remains safe, strong, and efficient!
