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 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 broad; that’s about an inch wider and taller than an strange piece of printer paper. They provide an incredible steadiness 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” circumstances as properly, simply with some further area left over.




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

Whereas there’s fewer most PCI slots comparatively, 4 continues to be a lot for many customers trying to construct a gaming PC. Nonetheless, decreased overclocking potential signifies that you will be unable 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 type issue advisable for PC constructing. Regardless of the ITX designation, mini-ITX motherboards are typically 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 good 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 fastidiously chosen, environment friendly {hardware} is a should in case you 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
