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 instances made to carry them are in no quick 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 atypical piece of printer paper. They provide an ideal stability between performance and worth that meets (or typically 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” instances as properly, simply with some additional house left over.




    • Dimension: 305mm x 244mm | 12” x 9.6”

    • Usually use weaker VRMs, which impedes overlocking


The Micro ATX kind issue may be really useful to these in search of options much like customary ATX on a price range. Motherboards of this kind issue usually sport the identical variety of CPU and RAM slots as an ordinary ATX board however at a lower cost. Whereas there’s fewer most PCI slots comparatively, 4 remains to be loads for many customers seeking to construct a gaming PC. Nonetheless, lowered overclocking potential implies that you won’t be able to push these motherboards to the extent of efficiency you’ll discover in customary 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 useful for PC constructing. Regardless of the ITX designation, mini-ITX motherboards are typically 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 if you happen to plan on gaming with a mini-ITX motherboard.



    • Dimension: 170mm x 170mm | 6.7” x 6.7”
