Motherboard standoffs

What Are Motherboard Standoffs and What Are They Used For?

The motherboard is one of the most critical components to install when assembling a PC. Since computer cabinets are built of metal, there must be room between the motherboard and the casing to avoid direct contact.

On both the back and front sides of a motherboard, there are several electrical connections. A standoff is a metal spacer that goes between your motherboard and the casing.

So, in the most basic sense, standoffs provide extra space between the motherboard and the chassis. While motherboard standoffs may appear to be insignificant, they are an essential component of PC construction.

What Are Motherboard Standoffs?

A motherboard standoff is a small cylindrical or hexagonal-shaped metallic object that screws into the designated mounting holes on the PC case. Standoffs are used to keep the motherboard separate from the CPU casing. It is also called motherboard mounting screws.

The motherboard standoffs are one-of-a-kind. They have threads on one end, just like a normal screw. This is the side of the standoff that is attached to the PC casing. The other end of the standoff’s hole is threaded on the inside.

The motherboard will be screwed in at this point. Instead of a top head, a standoff screw has an anchor into which motherboard screws can be inserted. Standoff screws are typically screwed into a casing.

The motherboard is then placed on top of the standoffs. Each motherboard screw necessitates the use of a standoff.

Depending on the motherboard form factor, different quantities of screws and standoffs are required (i.e., ATX, mATX, Mini-ITX).

What Is the Purpose of Installing Standoffs or Spacers?

There are a lot of complex electrical connections on the back of the motherboard, with hundreds of solder spots and electrical connectors.

The standoff acts as a barrier between the motherboard and the metal casing, preventing a short circuit in the motherboard when it comes into contact with the metallic computer case.

A short circuit will occur if the metals come into contact, destroying your computer. As a result, the motherboard must be raised so that it does not come into contact with the metallic PC chassis, which could result in a short circuit.

Aside from preventing dangerous short circuits, standoffs serve two other functions.

They accomplish two things: first, they securely hold the motherboard in place; second, the space they create helps to cool the motherboard during operations by allowing air to flow more freely.

Is It Compulsory to Use Motherboard Standoffs?

You most certainly do.

Many people wonder if a motherboard can be mounted without the use of standoffs. However, you should never assemble a PC without using proper motherboard standoffs.

Non-use of motherboard spacers may result in an electrical short circuit, resulting in total system damage and, in the worst-case scenario, endangering yourself.

Many computer cases include standoffs that are either built into the case or come preinstalled. You must ensure that your computer case supports the form factor of your motherboard, whether it has built-in, preinstalled, or individually supplied standoffs.

Do Motherboard Standoffs Come with the Motherboard?

No! They don’t own any. Standoffs are included (or built into) the computer case.

Many people believe that motherboards include screws and standoffs. The vast majority of the time, however, this is not the case.

Although motherboards are standardized within form factors, case shapes, sizes, and depths can vary greatly, necessitating the use of screws and standoffs to ensure compatibility.

When it comes to screws and standoffs in modern computers, however, there is a lot of consistency. For example, if you have standoffs from an ATX case, they will almost certainly work with any ATX board in any ATX case.

Where to Find Motherboard Standoffs?

Standoff screws are usually included with the computer cabinet when you buy them. If it is not available, try online stores such as Amazon and Newegg. They might also be available at your local computer store.

Check that the standoff you select is compatible with your case. They are inexpensive, with a pack of good quality Motherboard Standoffs Screw Kit only costing a few dollars on Amazon.

How Do You Put Motherboard Standoffs in Place?

Some PC cabinets come with brass hex standoffs that require a hex driver to install, while others come with a clip that snaps into the tray.

Unfortunately, neither the casing nor the motherboard comes with a hex driver. It is, therefore, preferable to obtain a hex driver for this purpose.

Position the motherboard so that all of the standoffs are visible through the mounting holes. Then, beginning with the center mounting point, insert the screws/clips to secure the motherboard to the cabinet.

The mounting holes’ locations will differ depending on the form factor of the motherboard. As a result, before you install the standoffs, double-check that you’ve matched and identified the specific holes required to mount your board form factor.

Also, ensure that it is just tight enough. Overtightening the standoffs may cause them to break or damage the case. The space beneath should be left empty to avoid any damage to the motherboard and to encourage adequate ventilation.

What Happens if Motherboard Standoffs Aren’t Used?

The purpose of the motherboard standoff screws has already been mentioned. These standoff spacers assist in raising the motherboard slightly above the computer case and avoiding a direct short circuit.

It’s impossible to predict whether you’ll fry your motherboard, CPU, or both, or whether your computer will fail to start without standoffs, but one of these outcomes is almost certain.

Simply put, if you install a motherboard without standoffs, you will be disappointed. Without exception, always take the time and care to install all of the screws and standoffs that your motherboard supports. This approach guarantees that the motherboard is never shorted.

What Is the Procedure for Removing Motherboard Standoffs?

Using needle-nose pliers, secure the standoff in place before loosening the motherboard screws. After that, the motherboard and standoff can be removed. A needle-nose plier is not a costly item for this purpose, and it is readily available on Amazon.

What Are the Materials Used in Standoffs?

For motherboard standoffs, brass, a copper-zinc alloy, is commonly used.

Although it is a metal, brass has a lower conductivity than pure copper or steel, making it useful for isolating circuits.

Brass also has excellent anti-rust properties. Standoffs, on the other hand, can be made of any material, including plastic.


Installing a standoff is a necessary part of building a PC, not an optional step.

They play an important role in preventing the motherboard from coming into contact with the casing and shorting out.

Standoffs for motherboards are commonly included with the case you buy for your motherboard. In a suitable case, you’ll find corresponding mounting holes for your board’s form factor.

One of the few things that most novices overlook when building a computer is the need for motherboard standoffs.

This article explained everything there is to know about motherboard standoffs, including what they are, why they are used, and how they should be positioned.

Yes, while installing a motherboard on a computer chassis, you must utilize motherboard standoffs. These standoff spacers help to raise the motherboard slightly above the computer case, preventing a direct short circuit.

What do motherboard standoffs do?

Motherboard standoffs are metal risers that keep your motherboard raised from the motherboard tray in your PC case. Standoffs are required to protect your components because if your motherboard comes into contact with your casing, the electric discharge might short the circuits on your motherboard, or possibly your RAM or CPU.

What size are motherboard standoffs?

A #6-32 UNC standoff is commonly used on motherboards and other circuit boards.

What happens if you install a motherboard without standoffs?

It is dependent on the case’s design and the material used. If it is metal, you risk shorting it out and maybe damaging the board if you fix the board without standoffs. There’s nothing to worry about if it’s non-conductive, like plastic.

What is the difference between a standoff and a spacer?

The primary distinction between a spacer and a standoff is that standoffs are threaded on both ends, whereas spacers are not.
