What Is UATX Motherboard? Guide and Comparison with ATX

Many newbie builders are stumped when trying to figure out What Is A ATX Motherboard. In addition, which method is the most effective. Let us take a closer look at what makes one form factor motherboard better than another so that you can make an informed decision about which one is Best for You. It is essential that you always carry a notebook. Since it was first introduced in December 1997 and first put into use in January 1998, MicroATX, also known as UX, has become a motherboard industry standard.

MicroATX motherboard format

A MicroATX motherboard can be up to 9.6 inches wide (244 244 mm). The term “micro ATX” refers to motherboards that are smaller than the standard ATX form factor of 244 205 mm (9.5 8.1 in). ATX Motherboards are 25% longer than conventional ATX Motherboards, at 12 9.6 inches (305 244 millimeters). It’s nearly impossible to compare motherboards because of the large variety of differences. Features, cost, size and other aspects must all be taken into account while making a decision.

The most important thing to keep in mind is that before making a purchase, you should perform as much research as possible. The ATX bus standard was intended to be backward compatible with MicroATX. Full-size ATX motherboards have all the mounting points, whereas MicroATX motherboards only have a subset of them, and the I/O panel is identical on both boards.

Because of this, MicroATX motherboards may be placed in full-size ATX cases without issue. Furthermore, microATX motherboards use the same power connectors as ATX motherboards, therefore full-size ATX power supplies can be used with microATX boards without modification.

There are many components that microATX boards can share with full-size ATX boards because of their use of the same chipsets (north and south bridges). MicroATX cases have fewer expansion slots than ATX cases since they are smaller in size than ATX cases.

ATX Motherboards typically contain seven PCI or PCI-Express expansion slots, while microATX boards only have four (four being the maximum permitted by the specification). In order to reduce space in the casing and expansion slots, many motherboard makers produce Micro ATX motherboards with integrated peripherals (especially integrated graphics). Small form factor and media center computers can be built using these motherboards.

It is possible to free up expansion slots using the ASRock G31M-S motherboard, which has integrated Intel GMA graphics, HD Audio, and Realtek Ethernet (among other capabilities), allowing it to do so. The conventional Northbridge/Southbridge pair has much of this functionality, therefore it has become common for ATX boards to have all of these components in recent years.

It is no longer necessary to have a huge number of expansion slots, and microATX may now be used in ATX cases because of the inclusion of “must-have” features on the motherboard. As a result of a recent study, budget-conscious DIY PC purchasers choose MicroATX Motherboards over full ATX Motherboards since the cost reductions for equivalent feature sets exceed the enhanced expandability afforded by extra PCI/PCI Express slots. Since 2006, high-end enthusiast gaming setups no longer require full-size ATX motherboards due to the availability of dual-GPU configurations on microATX motherboards.

Regulation of taxes is the responsibility of a UTAX Board.

If you’re spending a lot of money, what kind of motherboard should you get? Is there a difference between a UATX and an ATX motherboard in terms of performance? If you want to construct your own computer from the bottom up, one of the most important considerations you’ll have to make is which motherboard to choose. However, choosing the best one for you may be a challenge. It’s easy for people to become overly attached to a single firm or organization, and this can lead to a loss of perspective.

Comparing ATX and UATX

Comparing ATX and UATX

Analyzing them side by side, it’s possible that the UATX and the ATX will reveal some shared characteristics. On the other hand, it’s a little more difficult to tell the two groups apart. The size of their bodies is the most obvious distinction between them:

  • Micro-ATX (UATX): 9.6″ x 9.6″ vs. 12.0″ x 9.6″ in standard ATX
  • In terms of computer form factors, Mini-ITX (6.7′′x6.7′′) is the most common.
  • In comparison to a typical ATX motherboard, the UATX is only a few millimeters narrower. For some users, having more PCIe lanes available on an ATX motherboard may be an advantage.
  • If you need a multi-GPU setup or a big number of PCIe devices, ATX is the best choice. Only one or two lanes of PCIe can be found in the UATX, depending on the model. Because they are smaller in size, they can be used in smaller-sized cases. There are often more alternatives for tiny form-factor housings.
  • When comparing the sizes of UTAX and ATX Motherboards, keep in mind the types of PC cases you can use with each.
  • If you want to create a smaller gaming PC than what is currently available, you won’t be able to use an ATX motherboard. On the other hand, a UATX motherboard is the best option. Any motherboard will work as long as you don’t mind a larger chassis, and the rest of the configuration is left up to you.
  • When it comes to choosing a motherboard, you’ll have to take into account a number of other aspects, including the size of the case. Keep in mind that most medium and large-sized cases may fit a smaller motherboard. If you want a laptop that looks good, you should think about what a smaller motherboard can do in a larger casing.
  • With so much empty space in your case, everything will be pushed to the upper left corner. contrary to widespread perception, ATX motherboards cannot be used in smaller enclosures


A UATX Motherboard should now be clear to you. the differences between an uatx board and the way it functions Deep breaths. Consider what you truly require at this moment. In order to get the most out of your gaming experience, you must have the greatest alternatives available. Even if it takes a little extra effort, it’s well worth it. With any luck, you now have a clearer idea of what UATX form-factors are available and which one is most suited to your needs.
