What Are Motherboard Standoffs? Detailed Guide 2023

Assembling a PC is a great way to save money and ensure that you have a custom-built computer that meets your specific needs. However, it can be a daunting task, especially if you are not familiar with the various components of a computer.

One component that is often overlooked but is crucial for the stability and performance of a computer is motherboard standoffs. In this article, we will explore what are motherboard standoffs are, why they are important, and how to install them.

What Are Motherboard Standoffs?

Motherboard standoffs, also known as motherboard spacers, are small metal or plastic pieces that are used to create a gap between the motherboard and the computer case.

The standoffs screw into the case and provide a stable foundation for the motherboard to rest on. Without these standoffs, the motherboard would be in direct contact with the case, which could cause a short circuit and damage the motherboard.

Types of Motherboard Standoffs

There are two main types of motherboard standoffs: metal and plastic. The metal standoffs are made of brass or steel, while the plastic standoffs are made of nylon.

Both types serve the same purpose, but the metal standoffs are more durable and provide better grounding. However, plastic standoffs are often preferred by some builders because they are more forgiving and do not conduct electricity.

When selecting standoffs, it is essential to choose the right size and type for your motherboard and case. Most cases come with pre-installed standoffs, but it is crucial to check whether they match the motherboard’s mounting holes.

Using the wrong standoff size or type could cause damage to the motherboard or case.

Why Are Motherboard Standoffs Important?

Motherboard standoffs are important for several reasons:

1. Prevents Short Circuits: As mentioned earlier, motherboard standoffs create a gap between the motherboard and the case, preventing the motherboard from coming into contact with the conductive material of the case. This is essential because if the motherboard were to touch the case, it could cause a short circuit, which could damage the components of the motherboard.

2. Improves Airflow: Motherboard standoffs help to improve the airflow inside the computer case. By creating a gap between the motherboard and the case, air can circulate more freely around the motherboard, which helps to keep it cool. This is particularly important for high-performance systems that generate a lot of heat.

3. Provides Stability: Motherboard standoffs provide a stable foundation for the motherboard to rest on. This is important because the motherboard contains many delicate components that could be damaged if it is not properly secured.

How To Install Motherboard Standoffs?

Determine the Number of Standoffs Needed: The number of standoffs needed will depend on the size of the motherboard and the case. Most cases come with pre-drilled holes for standoffs, but you should consult the user manual to confirm the number and placement of standoffs required.

Screw in the Standoffs: Once you have determined the placement of the standoffs, screw them into the case using a screwdriver. Be careful not to over-tighten the screws, as this could damage the case or the standoff.

Align the Motherboard: Once the standoffs are in place, align the motherboard with the standoffs. The screw holes on the motherboard should line up with the standoffs.

Secure the Motherboard: Once the motherboard is aligned, use screws to secure it to the standoffs. Again, be careful not to over-tighten the screws.

Importance of Motherboard Standoffs

Motherboard standoffs are essential components in protecting the motherboard and ensuring that it works correctly. Without them, the motherboard would come into direct contact with the metal case, which could lead to a short circuit or even permanent damage to the motherboard.

Motherboards typically have many solder points underneath, which are sensitive to electrical interference. Any contact between the motherboard and the case could cause the solder points to short-circuit, leading to a non-functional motherboard. By installing standoffs, you create a buffer that prevents this from happening.


Motherboard standoffs are a crucial component in building a PC. They help to prevent short circuits, improve airflow, and provide a stable foundation for the motherboard.

When installing motherboard standoffs, it’s important to follow the user manual and not over-tighten the screws. By properly installing motherboard standoffs, you can ensure that your computer is stable, reliable, and performs at its best.


Q: What are standoffs used for?

A. Standoffs are small metal or plastic spacers used in electronic and computer hardware to create space between circuit boards and other components. They are used to support the circuit board and prevent it from touching other components, as well as to provide additional stability and support.

Q: What are standard motherboard standoffs?

A: Standard motherboard standoffs are small metal or plastic spacers that are used to mount a motherboard in a computer case. They are typically hexagonal in shape and come in a variety of sizes to fit different types of cases and motherboards. Standard standoffs are typically 6-32 threaded and come in different lengths to accommodate different case heights. They are often included with computer cases or can be purchased separately. It is important to use the correct size and type of standoff for your specific motherboard and case to ensure a secure and stable installation.
