Do you have the knowledge that it takes to build your PC? Are you ready to pick out the best motherboard that will fulfill your needs? Selecting a motherboard can be a confusing task due to the abundance of choices which lead to confusion about the exact type that suits you and your requirements. To the untrained eye, the most apparent difference between the ATX, Micro ATX, and Mini ITX would be their size, but there is more than meets the eye.
Many things set these motherboards apart, and our article highlights these differences to help you distinguish between them in a more educated manner. This post discusses the crucial factors that matter the most when selecting a motherboard for the purpose you require them to fulfill. Each variant is intended for a particular purpose; therefore, it is vital that you choose the correct one.
Let’s examine the basics:
ATX VS Micro ATX VS Mini ITX – Basic Features
Firstly, as we previously mentioned, the sizes of the ATX, Micro ATX, and Mini ITX are different, which is apparent in their physical dimensions. Still, they all meet the required standards, which makes them compatible with most computers’ chassis. Each motherboard has equally spaced mounting screws located on edge following the typical design for PC cases.
Usually, most chassis include multiple form-factor motherboard mounting, which will allow you to easily install your ATX, Mini ITX, and Micro ATX in the PC tower.
Following are the Motherboards’ standard dimensions:
|ATX VS Micro ATX VS Mini ITX|
|ATX||305 x 244 mm||12.0 x 9.6 inches|
|Micro ATX||244 x 244 mm||9.6 x 9.6 inches|
|Mini ITX||170 x 170 mm||6.7 x 6.7 inches|
The ATX is physically the largest among the three. However, in terms of the width, the ATX and Micro ATX are the same, but the similarities end there because the Micro ATX is shorter than ATXl considering tower PCs. To explain further, the Micro ATX will easily fit an ATX chassis, but a PC case with a Micro won’t be able to house an ATX motherboard.
Therefore, the form factor is an essential initial consideration when purchasing a motherboard. Ensure that the motherboard you go with is compatible with the PC case you have selected because incompatibility will be a costly mistake that should be avoided at all costs, especially for beginners.
Thankfully, installing the motherboard in a PC chassis is a simple task that most people can do by themselves. However, there are some minute details that one should be careful about to avoid any mounting and performance issues.
ATX is an abbreviation of Advanced Technology Extended, a standard created by Intel to ensure that various ATX components are physically and electrically compatible. The computer chassis and the power supply must follow the ATX standard and fit together.
VIA Technologies created the Mini-ITX, which is considered a smaller ATX. ITX is short for Information Technology eXtended.
It is important to remember that the dimensional differences between the Mini ITX, Micro ATX, and ATX play an essential part in nearly all aspects of this comparison. The size of each motherboard determines the number of chipsets and slots they can have on the PCB. The Mini ITX features only a single PCIe slot since it is the smallest among the three. Small-sized motherboards may only offer one built-in LAN and fewer connections for peripheral and limited storage device connections.
Most modern motherboards also have WiFi and Bluetooth connectivity because it has become a necessity. A majority of them come with the newest WiFi-6 and BT 5.1 connectivity. However, smaller motherboards might not offer these features.
Heat Transfer and Cable Management
The three motherboards make the best of the space available by adjusting all the components on board. However, the ATX motherboard, the largest of the three, offers the best heat transfer capability with bigger heatsinks on the chipset and VRM. Furthermore, the space allows for better cable management through the strategic placement of headers, which reduces any management issues.
But if you are comparing the Mini ITX vs. Micro ATX, their compact size means lesser space to cool down, which may require a high number of fans or AIO cooling with increased efficiency. The cable management on these motherboards is more complex.
The RAM capacity is another significant distinction between regular ATX, micro ATX, and tiny ITX. You’ll be relieved to discover that the standard and micro ATX motherboards can accommodate up to four modules. In contrast, the smallest board in the group can support up to two, implying that the ATX boards can handle at least twice as much capacity as the mini ITX boards.
If you wish to have additional room for upgrading, you should avoid choosing the mini ITX. This is not the ideal option if you intend to play more sophisticated games in the future.
The layouts of the different form factors are the most noticeable distinction between them. They differ in terms of the number of PCIe slots. The conventional ATX is your best bet in this regard. It has a capacity of 7 slots. The micro ATX, on the contrary hand, can hold as many as four, while the small ITX can only have one.
Depending on how you intend to use these spaces, this could be a deal-maker or a deal-breaker. They are useful for adding graphics cards, sound cards, and other expansions. That’s why, before diving in, you should figure out exactly what you’re searching for. You may be interested in a more compact PC but discover that it limits your ability to customize your PC setup as much as feasible on a larger motherboard.
Furthermore, we mentioned that micro ITX boards had PCIe slots right on edge, which could present issues with bigger graphics cards in the future.
The actual prices may be surprising to learn because the smallest motherboard – the Mini ITX, isn’t the cheapest. In fact, it might be the most expensive in terms of the starting prices. While the ATX and Micro ATX motherboards are priced around the $50 to $60 starting price range, the Mini ITX starts at $100. Remember that the Mini ITX is only preferable if you are building a compact gaming computer.
The Micro ATX motherboards are the cheapest among the three, but the ATX motherboards have the best value for money due to the higher number of PCIe slots.
ATX VS Micro ATX VS Mini ITX – Overview
Now we will be providing a quick overview of the motherboards, as well as the specifications they offer:
If you are building a workstation or a top-notch gaming PC, then ATX motherboards are a great option because they come with four ram slots, allowing you to increase your computer’s memory to your needs. You can run up to 32 GB ram on each slot.
While it may be too much Ram for gaming, various tests and benchmarks show that 8 GB and 16 GB ram offer minimal frame rates and performance differences. However, 32 GB of Ram might not be enough for a developer or PCs intended for professional work.
Another unique standout feature of the ATX motherboard is the 7 PCIe Slots that can support PCIe cards and Multi-GPU.
Furthermore, in terms of performance and additional upgrades to a PC, ATX is the top choice. Although the ATX is one of the most expensive and the biggest motherboards, they are worth the investment due to their versatile enhancement support.
Let’s examine the Pros and Cons of ATX.
- A higher number of PCIe Slots
