所謂主板結(jié)構(gòu)就是根據(jù)主板上各元器件的布局排列方式，尺寸大小，形狀，所使用的電源規(guī)格等制定出的通用標(biāo)準(zhǔn)，所有主板廠商都必須遵循。主板結(jié)構(gòu)分為AT、Baby-AT、ATX、Micro ATX、LPX、NLX、Flex ATX、E-ATX、WATX以及BTX等結(jié)構(gòu)。其中，AT和Baby-AT是多年前的老主板結(jié)構(gòu)，已經(jīng)淘汰；而LPX、NLX、Flex ATX則是ATX的變種，多見于國外的機(jī)，國內(nèi)尚不多見；E-ATX和W-ATX則多用于服務(wù)器/工作站主板；ATX是市場上常見的主板結(jié)構(gòu)，擴(kuò)展插槽較多，PCI插槽數(shù)量在4-6個(gè)，大多數(shù)主板都采用此結(jié)構(gòu)；Micro ATX又稱Mini ATX，是ATX結(jié)構(gòu)的簡化版，就是常說的“小板”，擴(kuò)展插槽較少，PCI插槽數(shù)量在3個(gè)或3個(gè)以下，多用于機(jī)并配備小型機(jī)箱；而BTX則是英特爾制定的一代主板結(jié)構(gòu)，但尚未流行便被放棄，繼續(xù)使用ATX。
