Hopefully, this will help you find the right screws and standoffs to keep your new system together and running smoothly. So let’s get started by discussing why you need them in the first place.

Why are motherboard screws and standoffs important?

Motherboard screws and standoffs are important components when building a computer. They serve several crucial functions:

Preventing Electrical Shorts:

Insulation: Standoffs are insulating spacers that lift the motherboard above the case. They prevent the conductive components on the back of the motherboard from making direct contact with the metal case, reducing the risk of electrical shorts.

Conductive Elements: Motherboards have circuits, traces, and solder points on their back. If these come into contact with the case, it could create unintended pathways for electricity, leading to short circuits.

Protection: The standoffs, by maintaining separation, protect the motherboard and its delicate components from potential damage caused by electrical shorts.

Ensuring Proper Alignment:

Form Factor Compatibility: Motherboards come in various sizes or form factors (e.g., ATX, microATX). Standoffs are positioned in the case according to the specific form factor, ensuring that the motherboard fits properly and aligns with the mounting holes.

Stability: Proper alignment provided by standoffs ensures that the motherboard is stable within the case. This stability is crucial for the overall structural integrity of the system.

Avoiding Misalignment Issues: Incorrect alignment may lead to difficulties in installing other components, such as expansion cards or cooling solutions, and may even result in physical damage during the installation process.

Facilitating Heat Dissipation:

Airflow: Standoffs elevate the motherboard, creating a gap that allows air to flow underneath and around its components. This promotes better airflow, preventing heat buildup.

Cooling Efficiency: Improved airflow helps dissipate heat generated by the motherboard’s various components, including the CPU, GPU, and power delivery components.

Preventing Overheating: Effective heat dissipation is essential for preventing components from overheating, which can lead to performance issues and reduced hardware lifespan.

Ensuring Stability and Security:

Secure Mounting: Motherboard screws fasten the motherboard securely to the standoffs, preventing any unintended movement or shifting. This secure mounting is vital for the long-term reliability of the system.

Vibration Resistance: Securely mounted motherboards are less susceptible to vibrations caused by moving parts, such as cooling fans or hard drives. This helps maintain component connections and reduces the risk of hardware failures.

Long-term Reliability: Stability provided by proper mounting contributes to the long-term reliability of the system by minimizing the wear and tear on connectors and preventing physical stress on the motherboard.

Simplifying Maintenance and Upgrades:

Accessibility: Well-mounted motherboards are easier to access during maintenance or upgrades, allowing for convenient installation or removal of components.

Component Connection: The secure connection facilitated by screws and standoffs simplifies the process of connecting and disconnecting various components, such as RAM modules, expansion cards, and power cables.

Reducing Wear and Tear: Properly secured motherboards are less likely to experience physical stress during component changes, reducing the risk of damage and ensuring a smoother upgrade or maintenance experience.

Do Motherboard Have Screws in the Same Location?

The location of the motherboard screws can vary from case to case. Generally speaking, most cases will have four mounting points for a standard ATX motherboard. These mounting points usually consist of two on each side at the corners of the board. However, some cases may have additional mounting points as well as other features such as a standoff or an I/O shield. Be sure to check your case specifications before purchasing or installing a new motherboard.

Different Motherboard Sizes:

The size of your motherboard is determined by its form factor. The most common form factors include ATX, Micro-ATX (mATX), and Mini-ITX. The size refers to both physical dimensions and layout; larger motherboards generally tend to provide more features than smaller ones but they also take up more space in the chassis. An ATX motherboard is typically 305mm x 244mm while an mATX is 244mm x 244mm and a Mini-ITX is 170mm x 170mm in size.

Different Sizes of Screws and Standoffs:

The size of the screws and standoffs you need for your build will depend on the form factor of your motherboard. For example, an ATX motherboard requires M3x6mm screws while mATX and Mini-ITX require M2.5x5mm or M2x3mm screws. The standoffs you need will also vary depending on the size of your motherboard; for example, an ATX motherboard requires 6mm standoffs while mATX and Mini-ITX need 5mm or 3mm ones respectively.

What happens if you don’t use standoffs?

If you do not use standoffs when installing your motherboard, there could be several issues that arise.

Electrical Shorts:

When standoffs are omitted during motherboard installation, the absence of a protective gap between the motherboard and the metal case exposes the system to the imminent danger of electrical shorts.

The conductive elements on the back of the motherboard, including traces and components, may inadvertently make contact with the conductive surface of the case.

This contact can give rise to electrical shorts, posing a severe threat to the motherboard’s integrity and causing irreversible damage to interconnected components.


The omission of standoffs results in the motherboard resting directly on the case, impeding the natural airflow crucial for effective cooling.

This compromised cooling mechanism can lead to overheating issues, affecting the performance and reliability of critical components such as the CPU and GPU.

Overheating not only induces performance degradation but also holds the potential for permanent damage to these essential hardware elements, jeopardizing the overall stability of the system.

Alignment Issues:

Standoffs play a pivotal role in aligning the motherboard with the case’s specific mounting holes. Without them, achieving precise alignment becomes challenging.

This misalignment not only complicates the secure attachment of the motherboard with screws but also introduces the risk of uneven pressure on the board, potentially causing physical damage and compromising the structural integrity of the system.

Vibration and Mechanical Stress:

Standoffs serve as stabilizing elements, mitigating vibrations originating from components like cooling fans and hard drives.

Their absence renders the motherboard more susceptible to these vibrations, exposing it to increased mechanical stress.

Prolonged exposure to mechanical stress can compromise the reliability of the motherboard and its connectors, introducing potential long-term issues that may affect the system’s overall stability and performance.

Difficulty in Component Installation:

Standoffs provide elevation and aid in aligning the motherboard with other case components.

Without them, the installation of additional components, such as expansion cards and memory modules, becomes arduous.

This lack of proper alignment can result in a less organized and more challenging build process, impacting the overall efficiency and functionality of the computer system.

Risk of Physical Damage:

The absence of standoffs heightens the risk of direct contact between the motherboard and the case, increasing the potential for physical damage.

This risk is particularly pronounced during the installation process or when making alterations to the system.

Without the protective buffer provided by standoffs, the motherboard becomes vulnerable to scratches, dents, and other forms of physical harm, compromising its aesthetic appeal and potentially impacting functionality.


As we talk earlier, in most cases, motherboards don’t come with screws and standoffs pre-installed.

You will need to purchase them separately according to the components you are using for your build. Different types of screws are used for different components.

Understanding the basic of screws and standoffs is important so that you can assemble all the required parts correctly and make sure your system is running at its best.


Do motherboards come with standoff screws?

No, motherboards do not come with standoff screws. Standoff screws are used to mount a motherboard in a PC case and are typically added separately from the motherboard itself. Generally, standalone screws can be purchased from any local hardware store or online retailer for relatively cheap prices. Standoff screws need to correspond with the size of the mounting holes in your frame and with the type of screw (and thread) provided on your motherboard. Therefore, it is important to select standoffs that match both before you buy them.

Are motherboards supposed to come with screws?

No, motherboards are not typically designed to come with screws. Many laptop and pre-built computers include a full set of components, including the motherboard, pre-installed in the case by the manufacturer and do not usually include extra screws aside from those necessary to fasten external peripherals. On the other hand, when building or modifying computer systems from scratch, additional screws may be required if none were included in the motherboard package. The type of screw needed depends on your case – some require small Phillips head screws while others need larger hexhead bolts – so make sure you have the right hardware handy.

Do Motherboards Come With M 2 Standoffs?

Yes, most motherboards come with M 2 standoffs. Depending on the size of your motherboard and its form factor, you will usually find two or four M 2 standoffs pre-installed in the mounting holes around the perimeter of your motherboard. The mounting holes allow for a secure connection between your board and any compatible device such as an SSD or tower case.

What Comes With Motherboard?

Motherboards usually come with a variety of components and accessories, depending on the exact model. These typically include the CPU socket, memory slots, power connectors, I/O ports (such as USB or Ethernet), expansion slots such as PCI Express and SATA connectors for connecting storage devices, fan headers for attaching cooling fans to your system, and other miscellaneous parts such as jumpers or capacitors. Additionally most motherboards also come with a thermal paste pre-applied to help dissipate heat from the CPU more effectively.

Are Motherboard Standoffs Preinstalled?

No, motherboard standoffs are not pre-installed. Standoffs generally come separately with either a case or motherboard package, and it’s up to you to make sure they’re installed correctly before beginning assembly. If you aren’t sure how many standoff screws are required for your particular build, refer to your user manual or consult an experienced builder for help.

Do All Motherboards Need Standoffs?

Yes, all motherboards should have standoffs installed in order to keep them secure and stable while they are mounted on the chassis. Standoffs provide a space between the motherboard and the chassis/case, which prevents any potential short circuits that may occur due to components touching each other. In some cases, standoffs also prevent components from vibrating too much due to fan movement or other sources of vibration inside the case.

Will Motherboard Turn On Without Standoffs?

No. Motherboards require the use of standoffs to keep the components from coming into contact with other conducting surfaces and causing short circuits or other related damage. The main purpose of standoffs is to prevent a ground loop when motherboards are installed into metal cases, which can be caused by contact between the board’s mounting holes and the case’s mounting points. Without standoffs, it won’t be possible for power to flow properly through all connections, which will prevent your motherboard from turning on.
