What is an ITX motherboard?

Introduction of ITX Motherboards

Information Technology Extended, or ITX, is a form factor for small computer motherboards developed by VIA Technologies. Typically smaller in size compared with other motherboard form factors such as ATX motherboards and microATX motherboards, Mini-ITX motherboards are designed to be used in small form factor (SFF) computing units, and to be used with small and low-power CPUs and fewer expansion slots and connectors, though a wide range of features, including USB, Ethernet, and audio, etc. are still considered standards.

ITX motherboards are popular when it comes to building small, powerful, and portable systems to fit in tight spaces, and are often used in embedded systems, such as kiosks and digital signage.

How Has The ITX Motherboard Evolved Over Time?

Development of ITX Motherboards

Since the introduction of the original ITX form factor in 2001, there have been several different variations and, needless to say, improvements. For example, Mini-ITX, which was introduced in 2001 has a size of only 17 cm x 17 cm. Nano-ITX, introduced in 2003, is even smaller than Mini-ITX, with a size of 12 cm x 12 cm. Pico-ITX, introduced in 2007, is one of the smallest SBC form factors, with a size of only 10 cm x 7.2 cm.

In addition to the different motherboard size variations, the ITX form factor has also evolved to include new features and technologies. For example, newer ITX motherboards are now equipped with more advanced features, such as support for faster processors, more memory, and more I/O ports. They also often include additional technologies, such as Wi-Fi, Bluetooth, and USB 3.2 support. Overall, the ITX form factor has evolved to become smaller, more advanced, and more versatile, making it a popular option for a motherboard in size-sensitive applications.

How to choose the best ITX motherboards?

As you attempt to choose an ITX motherboard that you think you are going to need, you may start to realize there are certain criteria–some criteria might matter more than others–that you will have to meet solely depending on the industry your PC is to serve in. Just to name a few of common concerns that will definitely arise, your application may rely on, for example, more computing power than storage, more networking than peripheral connection, more display finesse than control signals, and so on.

These concerns will dictate your purchase of the ITX motherboard as you do want everything in your business to be on the money. So, with a quick glance over the following sections, you will have a rudimentary of the criteria to guide you, and when it's time to build your PC, you will know what features and strong suits of the motherboard options on the market are going to be crucial or decorative, aka waste of money.

What hardware do I want to keep?

If you're only upgrading your PC  system, you might want to first ask yourself what has been going well with the previous ITX motherboard and what hasn't. Since hardware upgrade is closely linked to the amount of downtime of your business, you certainly would not want to end up regretting the setup and having to power down the system for any minor hardware adjustments. Any underperforming services and potential problems such as glitchy imaging cameras or poor WiFi speed stability should immediately go on the list of your priorities. Find out where the problem occurs. Is it the low bandwidth USB port that cannot give the high-resolution camera enough leeway? Is it the old SATA drive that caused the program to crash from time to time? If there are peripherals that you do not wish to upgrade along with the ITX board at the moment, make sure they are good as new. Record all the existing unsatisfactory performances and test them out before you earmark the budgets.

What hardware has to go on the motherboard board?

For building new systems, this would be the most urgent question. It all comes down to what applications will be implemented in your business. Here are a few rules of thumb that might guide you to the right questions to ask, but you have to expect that the answer will always have some tradeoffs.

  • What is prioritized in the application? Is it computing power, space, storage, graphics, control signals, etc.?
  • Is the system going to be a workhorse and heavily used in incessant computing, including the TDP desktop CPU and the GPU? Do I need to budget carefully for power consumption and room for cooling systems?
  • Do I have to save space by going for m.2 SSD storage and WiFi cards, or do I not care about size and plain old chunky SATA drives and GbE ports–do not forget the fiber cables that come into place–are more than welcome.
  • Is PCI-E for graphics cards essential to my business? Can integrated graphics processing capability in the CPU handle the tasks such as dual display, image processing, video streaming, etc. that my business deems essential?
  • Does the service rely on rapid and instantaneous tasks so I have to make sure there is enough memory? Is 16G enough? Or should I bump it up to 64G?

What other features do I need in an ITX Motherboard?

Certain ITX motherboards are designed to cater to certain industries. Not only hardware but also firmware and software features that are compatible with certain brands of providers can be what you're looking for, and you have to be careful when choosing compatible ITX motherboards. Bundled services and niche industry requirements such as tamper-proof storage and rugged designs might be paramount when the decisive moment presents itself. Beware of these added values that can be in conflict with the hardware features that you think you need but wouldn't be worse off without.

Here are some standardized and widely adopted firmware features for you to consider:

  • Overclocking for temporary demands of performance
  • AI optimizations for automatic optimal performance in different scenarios
  • Security such as encryption and secure boot
  • VM ware support for different operations systems in one computer
  • NVMe for extra SSD speed boost and RAID for data redundancy and data loss prevention
  • BIOS or UEFI remote management for easy maintenance

For the software features, most of them are manufacturers' proprietary enhancements that go with their hardware products. These enhancements include:

  • Software utilities to optimize performance and monitor hardware status
  • Audio and graphics fine-tuning software for the best experience
  • Network controllers and adapters, Bluetooth controllers, and other connectivity-based software configurations

The added values of the above can seem inconsequential at first, and that's probably because we as end users are accustomed to working with computers that are already fine-tuned without realizing it. But once you have made a new purchase and overlooked these features, the impact of lacking them could be devastating.

Cost and budget

The quality, performance, and durability of the ITX motherboard you procure in the end have much to do with your choice of brand and price. But they are definitely not to be overstressed. Reputable and sizable motherboard manufacturers provide advantages that will benefit you in the long run but also may trick you in terms of decision-making. Ask yourself these questions and see how important they are in impacting your business operation:

  • Are global brand names more reliable than local businesses? What reviews can I find to support that going for particular pricey brand names will guarantee a fitting future payoff?
  • Does the motherboard come with a warranty? Does the warranty reflect truthfully about the set price?
  • Have I or any source of information dealing with the brand name in terms of after-sale services? Are the sales representatives helpful in getting you prompt solutions to mitigate your loss?
  • When there's a stalemate during your sourcing, does the brand name provide you a fair comparison with their competitors or do they deny the merits of going for other manufacturers?

At the end of the day, it's you who has to talk to the provider when maintenance and defects call for their service again. Get to know possible and predictable future scenarios and make sure when adversities occur, the cost of the product can honestly reflect how much toil that comes your way.

A Quick Peek at the Recommended Mini-ITX Motherboards

As of date, the discussion of choosing amongst motherboard manufacturing tycoons has not ceased being a hot invigorating topic. As a disinterested decision maker who seeks to source the best mini-ITX option for your business (which we assume you are) instead of a fervent believer of certain brands, you will find this quick walkthrough section very practical in guiding you through the main differences in mini-ITX boards of different manufactures.

In September 2022, the latest flagships that were built with the new chipsets Intel Z790 and AMD X670 obsoleted the existing motherboard market, especially those targeting the gaming industry, boasting their compatibility with the latest processors: Intel 13th-Gen Raptor Lake and AMD Ryzen 7000 Series. And amongst the standard ATX motherboards and other larger boards released, we are certainly flabbergasted that mini-ITX form factors are not entirely overlooked:

  • ASUS ROG STRIX Z790-I GAMING (Intel 13th-Gen)
  • MSI MPG Z790i EDGE (Intel 13th-Gen)
  • ASUS ROG STRIX X670E-I GAMING (AMD Ryzen 7000)
  • ASROCK Z790M-ITX (Intel 13th-Gen)

Needless to say, ASUS has always set the price mountain high (Amazon). MSI, by going in a different direction–RAID support–leaves out the PCI-E 5.0 x4 M.2 2280 storage, the key feat reflected by the prices of ASUS ROG STRIX Z790-I and X670E-I. Whether the 100-dollar difference in price is worth, it depends on your budget range.

The only feature that makes the slashing price of ASUS ROG STRIX Z790-I worth it is probably (and very subjectively) the two Thunderbolt™ 4, USB 3.2 Gen 2 ports. The potential of this spec is limitless (40 Gbps bandwidth and quick charging), but it is quite unsure how many of the customers are going to see the benefit of it.

On the second tier of these newly released products, mini ITX is again not the star of the show but not entirely left out. By going for Intel chipset B650, for example, ASUS ROG STRIX B650E-I, you can still enjoy the merits of the PCI-E 5.0 x4 M.2 2280 storage along with AMD Ryzen 7000 series processors.

But if you only care about the latest processors, MSI MPG B650I Edge WiFi might not even seem a bad idea:

At the end of the day, you are still helping your business with the latest support of DDR5 memories with the overclocking speed of 6400+ MHz, the powerhouses of Intel 13th-Gen Raptor Lake and AMD Ryzen 7000 Series, and the PCI-E 5.0 x16 graphics. So, the hundred-dollar differences in the amount of USB 3.2 Gen 2 ports and the PCI-E 5.0 x4 M.2 SSD could be the more decisive factors you might really mull over before you whip out the cash.
