How to Choose Between MATX Motherboard and ATX Motherboard
Micro ATX maintains the position of the peripheral interface on the backplane of the ATX standard motherboard and is compatible with ATX. The Micro ATX motherboard reduces the number of expansion slots to 3-4, and the number of DIMM slots to 2-3, which reduces the width of the motherboard from the horizontal direction, and its total area is reduced by about 0.92 square inches, which is more compact than the ATX standard motherboard structure.
