This permits for widespread compatibility of motherboards and instances from totally different producers. As well as, a motherboard of a particular kind issue can match into some bigger kind issue instances, as a result of consistency of mounting screw areas, however the reverse isn’t true. As stunning as it could be, an “Prolonged ATX” motherboard won’t match right into a “micro ATX” case!

Totally different kind elements swimsuit totally different kinds of PCs: bigger motherboards are extra highly effective and possess extra options, however usually demand increased value tags and at all times require bigger instances. Smaller kind elements can produce quiet, compact PCs, however with some sacrifices when it comes to efficiency and compatibility.

Let’s take a better take a look at the advantages and disadvantages of a number of the hottest motherboard kind elements in the marketplace! We’ll begin with the commonest and work all the way down to the rarer varieties, itemizing off specs and a few professionals and cons for every as we go.

The fundamental kind issue since its introduction by Intel in 1995, the usual ATX kind issue is the bread and butter of the buyer computing world. Most motherboards produced are of ordinary ATX dimension, and the mid-tower instances made to carry them are in no brief provide (but). These motherboards are comparatively giant, measuring 305 millimeters tall and 244 millimeters huge; that’s about an inch wider and taller than an strange piece of printer paper. They provide a fantastic steadiness between performance and value that meets (or usually exceeds) the wants of the common shopper. These motherboards will match right into a case designated both “ATX” or “mid-tower”, however they’ll additionally match into bigger EATX or “full tower” instances as effectively, simply with some additional house left over.




    • Dimension: 305mm x 244mm | 12” x 9.6”
    • Common CPU sockets: 1
    • Common RAM slots: 4
    • Max PCI slots: 7
    • Common SATA ports: 6-12
    • Suitable instances: Mid-tower (ATX), Full tower (EATX)


    • Quite common, big market choice
    • Loads of RAM and PCI slots
    • Good price-to-performance ratio

    • Can solely match mid-tower or bigger instances


Customary ATX motherboards are primarily really useful for these needing a gaming laptop or a traditional workplace PC. The big variety of PCI slots permits for a bevy of graphics playing cards, sound playing cards, and different {hardware} to be put in (relying on the precise motherboard’s slot varieties). 4 RAM slots permit for in depth reminiscence capability, good for demanding workstation actions or gaming when you produce other duties open on a number of displays. However the comparatively giant dimension of this manner issue means that you’re normally restricted from utilizing a case smaller than a mid-tower, which can or could not introduce points into your construct.

Micro ATX

The Micro ATX kind issue is basically a typical ATX motherboard shortened right into a sq. on the costly of dropping three PCI slots. This manner issue is appropriate with ATX instances and energy provides, and infrequently makes use of the identical chipsets as their full-sized brethren. Measuring 9.6” tall in addition to huge, these squat motherboards are glorious choices for funds builds as their decrease variety of PCI slots and comparatively weaker overclocking efficiency knocks the value down just a few notches. Including to their worth is their versatility: along with micro ATX mini towers, micro ATX motherboards can match into any mid- or full tower case that helps different ATX kind elements… for those who can abdomen the unused house.




    • Dimension: 244mm x 244mm | 9.6” x 9.6”

    • Matches into all however the smallest instances
    • Cheaper than different fashionable kind elements


    • Fewer PCI slots than customary ATX
    • Usually use weaker VRMs, which impedes overlocking


The Micro ATX kind issue could be really useful to these on the lookout for options just like customary ATX on a funds. Motherboards of this manner issue sometimes sport the identical variety of CPU and RAM slots as a typical ATX board however at a cheaper price. Whereas there’s fewer most PCI slots comparatively, 4 remains to be loads for many shoppers trying to construct a gaming PC. Nevertheless, decreased overclocking potential implies that you won’t be able to push these motherboards to the extent of efficiency you’d discover in customary ATX or EATX.


Initially created as a compact motherboard that forgoes the necessity for cooling followers (sometimes now not true), the mini-ITX is the smallest kind issue really useful for PC constructing. Regardless of the ITX designation, mini-ITX motherboards are usually nonetheless appropriate with all sizes of ATX instances, together with micro-ATX, mid-tower, and full-tower. These tiny sq. boards are simply above 6” lengthy on either side—an ultra-small board good for small-footprint PCs the place emphasis is positioned extra on look, house effectivity, or portability than on uncooked energy. Sporting a single PCI slot and two RAM slots means rigorously chosen, environment friendly {hardware} is a should for those who plan on gaming with a mini-ITX motherboard.



    • Dimension: 170mm x 170mm | 6.7” x 6.7”
    • Common CPU sockets: 1
    • Common RAM slots: 2
    • Max PCI slots: 1
    • Common SATA ports: 2-6
