Are All Motherboards The Same Size

The motherboard is one of the most important components of a computer because it is connected to other components, such as RAM, graphics cards, storage devices, power supplies, etc. There are a variety of sizes, shapes, and models available in the market when purchasing a motherboard. There have been a lot of questions related to Are All Motherboards the Same Size.

It is of the utmost importance that you pick the right size motherboard if you plan on building a new PC. A motherboard is a key component of the performance of your PC, as different sizes of motherboards have different expansion slots, which are capable of supporting different types of hardware, which can have a substantial impact on your PC’s performance.

The motherboard plays a major role in the performance of a computer system, as it is apart from the case the most important component. Besides being able to connect all the components, it also provides a variety of functions such as audio, networking, ports/slots, etc., all of which make it very useful.

Are All Motherboards the Same Size?

Are All Motherboards the Same Size

Depending on the size and shape of the motherboard, there are different kinds of motherboards available on the market. In general, there are four common motherboard types and sizes: Extended ATX, ATX, Micro-ATX, and mini-ITX. Below is an explanation of each of these motherboard types.

ATX

The ATX stands for Advanced Technology Extended motherboard. There are several reasons why you should choose the ATX motherboard if you are planning to build a gaming computer. I would like to point out that this is the most commonly used motherboard design and its dimensions are 12 × 9.6 (305 × 244 mm).

ATX motherboards are the most popular gaming motherboards on the market, as they are the most commonly used motherboards for PC gaming. There are a number of choices you can select from when it comes to these motherboards. You can easily select a motherboard that complements your needs, tastes, and requirements, based on the type of motherboard you are looking for. 

As compared to Extended ATX motherboards, ATX motherboards have a smaller size compared to extended ATX motherboards. The ATX motherboard has four DIMM slots, which is why its width is smaller than its height, but its height is the same as E-ATX. There is quite a bit of similarity between the configurations of other ports and slots on ATX motherboards and those on E-ATX motherboards. 

Extended ATX (EATX)

In comparison to ATX motherboards, EATX motherboards are larger in size. A powerful gaming PC is best built with one of these motherboards. There is no doubt that these motherboards perform well and make a great choice when it comes to reliability and smoothness. 

Due to their size, EATX motherboards are unable to fit into compact computer cases, which is one of the reasons why they are incompatible with them. This particular motherboard has a dimension of 12 inches wide by 9.6 inches deep (305 mm x 244 mm), and it weighs about 15 pounds.

It is common to have eight DIMM slots, eight SATA ports, five or six PCI-E slots, and two or three M.2 slots on a motherboard. Due to their large size, these motherboards are only suitable for use in large PC cases since they have a large size and are not suitable for use in small PC cases.

It is most commonly used to mount these motherboards into full tower cases, although it is also possible to mount these motherboards into some higher-end mid-tower cases in cases.

Besides being designed in a better way, these motherboards are also much more expensive than most of the motherboards that are used almost daily, and they are also generally more expensive than most of the motherboards that are used every day.            

Micro-ATX Motherboards

A Micro ATX (mATX) motherboard is a smaller version of the ATX motherboards, which allows the motherboard to be fitted into a smaller casing. There are only a few centimeters of difference between microATX and ATX motherboards, and there are only a few centimeters of difference between the two types.

If you are looking for a motherboard that is not too expensive yet offers the features you are looking for, Micro ATX (mATX) motherboards are exactly what you are looking for. There is simply no difference between a normal ATX motherboard and one of these motherboards in terms of their specifications. When it comes to their size, however, they are a bit larger.

I find it quite interesting to see how the micro-ATX motherboards are configured in terms of their specifications. This motherboard’s width is pretty much the same as the width of the ATX motherboard, but its height is much less than the ATX motherboard’s height. This is why the PCI-E and M.2 slots on these motherboards are fewer than on some other motherboards.

Mini-ITX

According to our knowledge, Mini ITX motherboards are the smallest motherboards on the market for computers at the time of the writing of this article. It should be noted that Mini ITX motherboards have only two RAM slots, so you can only use 32GB of RAM if you pair up 16x2GB RAM sticks and connect them to the socket. It is important to note that there is no difference in size between a MINI ITX motherboard and a Micro ATX motherboard.

A MINI ITX motherboard has only two RAM slots. It is generally accepted that these motherboards are the smallest motherboards, and as a result, they are the most compact motherboards available. A large VRM section and a larger number of heatsinks are very rare to find on Mini ITX motherboards.

It is true that the performance of a system fitted with an ATX motherboard and one fitted with a mini-ITX motherboard will be the same so long as the case of the system is designed with a performance-oriented design.

Nano-ITX

In comparison to Mini ITX motherboards, Nano ITX motherboards are smaller in size. As far as I know, these motherboards have been on the market since 2003. The power consumption of these small motherboards is very low.

Those motherboards are of the size 12 cm by 12 cm (4.7 cm by 4.7 cm). This motherboard is specifically designed to be used with small computers, such as personal video recorders and smart TVs, as well as other devices, such as game consoles and other devices.

Pico-ITX

In 2007, VIA Technologies (Very Innovative Architecture Technologies), one of the world’s leading motherboard manufacturers, launched the Pico-ITX motherboard, the smallest form factor motherboard so far.

A PicoITX motherboard measures 10 x 7.2 cm (3.9 x 2.8), which is half the size of a Nano-ITX motherboard at 10 x 7.2 cm, which is the same size as a PicoITX motherboard. The size of the Nano-ITX motherboard is 10 x 2.2 cm (3.9 x 2.7 inches).

Pico-ITX motherboards are widely used in many different types of computers, such as media center computers, car computers, or even small home servers, which use a Pico-ITX motherboard. These motherboards have a number of components that are permanently installed on them, such as RAM and Processors, which cannot be replaced.

Conclusion

The information I have given in this article should have helped you gain a better understanding of all the sizes of motherboards since I have explained each one above. There are plenty of fair-priced ATX motherboards available for gamers and overclockers who are looking for motherboards with an affordable price tag.

A MicroATX or a Mini-ITX motherboard is also an option you should consider if you are looking for a mobo that is budget-friendly. There are two types of motherboards: Nano and Pico ITX, which are the smallest of all the motherboard types and are used for computers and smart TVs that are in cars.

Frequently Asked Questions

Do all motherboards fit in any case?

It is very important to note that the short answer to “Do all motherboards fit in any case?” is a big NO. It is important to note that not all motherboards can fit into all PC cases. This is because both the motherboard and the PC case are available in a variety of sizes.

How do I know if a motherboard will fit?

If you measure what is already inside of your case, you can figure out what size motherboard is going to fit inside of it. If you don’t know which size motherboard will fit in the case you are planning to use, the best thing to do is to purchase an ATX board if it is compatible with the case you are planning to use. 

Can I put any motherboard on my PC?

There are many different types of cases that are available on the market, most of which are designed to fit ATX motherboards, but some of them can also accommodate mATX motherboards, and still, others can even accommodate even smaller ITX motherboards. You should make sure that the motherboard you are searching for is compatible with the case of your computer in order to limit your search.
