This permits for widespread compatibility of motherboards and circumstances from completely different producers. As well as, a motherboard of a particular kind issue can match into some bigger kind issue circumstances, because of the consistency of mounting screw places, however the reverse isn’t true. As surprising as it might be, an “Prolonged ATX” motherboard is not going to match right into a “micro ATX” case!

Completely different kind elements swimsuit completely different types of PCs: bigger motherboards are extra highly effective and possess extra options, however usually demand greater value tags and all the time require bigger circumstances. Smaller kind elements can produce quiet, compact PCs, however with some sacrifices by way of efficiency and compatibility.

Let’s take a more in-depth 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 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 Elements

The fundamental kind issue since its introduction by Intel in 1995, the usual ATX kind issue is the bread and butter of the patron computing world. Most motherboards produced are of normal ATX dimension, and the mid-tower circumstances made to carry them are in no brief provide (but). These motherboards are comparatively giant, measuring 305 millimeters tall and 244 millimeters extensive; that’s about an inch wider and taller than an atypical piece of printer paper. They provide a fantastic steadiness between performance and value that meets (or usually exceeds) the wants of the typical client. 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 effectively, simply with some additional area 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 circumstances: Mid-tower (ATX), Full tower (EATX)


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

Micro ATX

The Micro ATX kind issue is actually a normal ATX motherboard shortened right into a sq. on the costly of dropping three PCI slots. This kind 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 extensive, these squat motherboards are wonderful 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… if you happen to can abdomen the unused area.




    • Dimension: 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)


    • Suits into all however the smallest circumstances
    • Cheaper than different fashionable kind elements


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


The Micro ATX kind issue will be really helpful to these on the lookout for options much like commonplace ATX on a funds. Motherboards of this manner issue usually sport the identical variety of CPU and RAM slots as a normal ATX board however at a cheaper price. Whereas there’s fewer most PCI slots comparatively, 4 continues to be lots for many customers trying to construct a gaming PC. Nevertheless, decreased overclocking potential implies that you will be unable to push these motherboards to the extent of efficiency you’ll 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 kind issue really helpful 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 either side—an ultra-small board excellent for small-footprint PCs the place emphasis is positioned extra on look, area 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 if you happen to 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
    • Suitable circumstances: Mini-ITX, Mini tower (Micro-ATX), Mid-tower (ATX), full tower (EATX)
