How Can You Put a Micro ATX Motherboard In ATX Case? Guide

MicroATX (sometimes called μATX, uATX, or mATX) is a motherboard standard introduced in September 1997. The maximum size of a microATX motherboard is 9.6 x 9.6 inches. However, there are examples of motherboards using the microATX notation despite being smaller than 244 x 205 mm (9.6 x 8.1 inches). You can get best cases for Micro ATX.

The standard ATX size is 25% bigger at 12 x 9.6 inches (305 x 244mm).

How Big is a Micro ATX Motherboard?

The main query mostly people ask, can you put micro atx motherboard in an atx case? You have to understand the features to look into find how big it should be.

Backward Compatibility:

The microATX specially designed for backward compatibility with ATX. The mount points for it are a subset using on full-size ATX boards and have identical I / O panels. Thus, MicroATX motherboards can use in full-sized ATX cases.

In addition, most MicroATX motherboards tend to use the same power connectors as ATX motherboards. It allows full-sized ATX power supplies for use with MicroATX motherboards.

Finally, microATX boards typically use the same chipset (northbridge and southbridge) as full-size ATX boards, allowing them to use many of the same components. However, mATX cases are generally much smaller than ATX cases, and they have fewer expansion slots.

Scalability: 

Many manufacturers release MicroATX motherboards with a full complement of integrated peripherals devices (particularly integrated graphics). These can serve as the basis for small form factor PCs and multimedia centers.

Scalability of micro ATX motherboard

For example, the ASRock G31MS motherboard includes integrated Intel GMA HD graphics, audio, and Realtek Ethernet (among others). Thus freeing up expansion slots already used for graphics cards, sound, and network cards. However, it has become even more common for ATX boards to integrate all of these components in recent years. Most of these functions are contained in a typical north/southbridge chip pair.

Since motherboards already have “must-have” features, there is no need for multiple expansion slots. The use of microATX has even increased for use in ATX cases.  In the home PC market, microATX motherboards are often the go-to motherboard of choice.

The feature-parity savings outweigh the added scalability of additional PCI-Express slot features provided by full ATX versions on microATX motherboards for professional gaming enthusiasts, further reducing the need for full ATX motherboards.

In addition, some microATX chassis require low-profile PCI cards and custom-sized power supplies. Compared to MiniITX, microATX motherboards have up to four expansion slots and four DIMM slots instead of one expansion slot and two DIMMs (or SODIMMs) on MiniITX motherboards. It means that the microATX supports dual graphics and quad-channel memory configurations.

Does Micro ATX Fit In ATX Case?

Micro ATX motherboards will fit and function properly inside an ATX case. Its benefits include better airflow, room for upgrades, more drive bays, and more space for wiring. The only drawback is that the PC case size is much larger. The motherboard can look very small compared to the case.  However, the answer of will micro ATX fit in atx case depends on many other factors.

Does Micro ATX Fit In ATX Case

Therefore, you would pay attention to the following points:

  • The unused motherboard space can be used for other devices. (additional drive bays, water coolers for components, internal USB hubs, the background I / O boards, etc.) 
  • Inner box black color does not draw attention to unused space, but the primary color of unpainted aluminum or steel will make it more visible. 
  • Do you use interior lighting in the case? If so, where is the light concentrated? Again, if the light only illuminates an area of ​​the motherboard and leaves the rest of the case in the dark, it will make the uatx motherboard size less noticeable. 

However, in the end, a beautiful motherboard, in your case or not, is a matter of personal preference and opinion. Honestly, it is your computer, and your own opinion is very important.

Can I fit a Micro ATX Motherboard in a Mid Tower Case?

Yes, full tower and micro atx mid tower cases fits in standard ATX motherboards, which are by far the most common motherboard sizes. Both can also work with smaller mATX motherboards. The exact dimensions vary by case type, but most mid-size cases reach around 18 inches in height and 8 inches in width.

The mounting holes on the mATX board are the same as on the ATX board. Only there are fewer holes in them because the board is not that big. In this case, you should have no problem using this motherboard.

Is a Micro ATX Motherboard Good?

Yes, Micro ATX is a smaller version of ATX. However, it has excellent performance and a much lower price tag. This is especially handy if you are looking for a more personal adjustment of micro atx in atx case, only do this when you need all the additional PCIe slots.

Summaries Words
While there are several form factors besides microATX and ATX, these are the 2 most common motherboard sizes used in gaming PC builds. mATX and ATX motherboards have pros and cons. mATX boards are an ideal space-saving option but often overlooked features. ATX boards have many features, but they are a little more expensive.
In the end, you decide which type depends entirely on your building plans and how much money you have in your budget. There is no performance difference between mATX or ATX motherboards, no difference in overclocking (on equivalent motherboards), and ultimately no reason to choose one over the other than your personal needs. Just make sure your motherboard is compatible with the CPU socket and runs on the correct chipset, and also make sure your motherboard and case are compatible with each other.
