This enables for widespread compatibility of motherboards and circumstances from totally different producers. As well as, a motherboard of a selected type issue can match into some bigger type issue circumstances, because of the consistency of mounting screw areas, however the reverse will not be true. As stunning as it might be, an “Prolonged ATX” motherboard is not going to match right into a “micro ATX” case!

Totally different type elements go well with totally different types of PCs: bigger motherboards are extra highly effective and possess extra options, however usually demand increased value tags and all the time require bigger circumstances. Smaller type elements can produce quiet, compact PCs, however with some sacrifices when it comes to efficiency and compatibility.

Let’s take a more in-depth take a look at the advantages and downsides of a few of the hottest motherboard type elements in the marketplace! We’ll begin with the most typical and work right down to the rarer sorts, itemizing off specs and a few execs and cons for every as we go.


Widespread Type Components

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




    • Measurement: 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 circumstances: Mid-tower (ATX), Full tower (EATX)


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


    • Trendy chipsets and options could be dear
    • Can solely match mid-tower or bigger circumstances


Normal ATX motherboards are primarily really useful for these needing a gaming laptop or a standard 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 particular motherboard’s slot sorts). 4 RAM slots permit for intensive reminiscence capability, excellent for demanding workstation actions or gaming when you produce other duties open on a number of displays.

Micro ATX

The Micro ATX type issue is actually an ordinary ATX motherboard shortened right into a sq. on the costly of shedding three PCI slots. This manner issue is appropriate with ATX circumstances and energy provides, and sometimes makes use of the identical chipsets as their full-sized brethren. Measuring 9.6” tall in addition to huge, these squat motherboards are wonderful choices for finances builds as their decrease variety of PCI slots and comparatively weaker overclocking efficiency knocks the value down a couple of 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 type elements… in case you can abdomen the unused house.




    • Measurement: 244mm x 244mm | 9.6” x 9.6”
    • Common CPU sockets: 1
    • Common RAM slots: 4

    • Common SATA ports: 4-8
    • Suitable circumstances: Micro-ATX, Mid-tower (ATX), Full tower (EATX)


    • Matches into all however the smallest circumstances
    • Cheaper than different well-liked type elements


    • Fewer PCI slots than commonplace ATX
    • Typically use weaker VRMs, which impedes overlocking


The Micro ATX type issue could be really useful to these searching for options much like commonplace ATX on a finances. Motherboards of this kind issue usually sport the identical variety of CPU and RAM slots as an ordinary ATX board however at a cheaper price. Whereas there’s fewer most PCI slots comparatively, 4 remains to be loads for many customers trying to construct a gaming PC. Nevertheless, diminished overclocking potential implies that you will be unable to push these motherboards to the extent of efficiency you’d discover in commonplace ATX or EATX.


Initially created as a compact motherboard that forgoes the necessity for cooling followers (usually not true), the mini-ITX is the smallest type issue really useful for PC constructing. Regardless of the ITX designation, mini-ITX motherboards are usually nonetheless appropriate with all sizes of ATX circumstances, together with micro-ATX, mid-tower, and full-tower. These tiny sq. boards are simply above 6” lengthy on each side—an ultra-small board excellent 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 fastidiously chosen, environment friendly {hardware} is a should in case you plan on gaming with a mini-ITX motherboard.



    • Measurement: 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
