What is microATX in the computer

microATX is the name of a computer board structure, also known as the mini ATX structure, which is a simplified version of the ATX structure.

Role

The main purpose of the Micro ATX specification is to reduce the overall cost of the PC system and to reduce the power requirements of the computer system.

Structural characteristics

The main features of the Micro ATX architecture are smaller motherboard sizes, smaller power supplies, and lower motherboard and power supply dimensions that directly reflect the cost of the computer system. While reducing the size of the motherboard can reduce costs, the number of I/O expansion slots available on the motherboard is relatively reduced, and the Micro ATX supports up to four expansion slots, which can be a combination of various specifications, such as ISA, PCI, or AGP, depending on the motherboard manufacturer.

Expansion slots

The Micro ATX Motherboard reduces the expansion slots to 3-4, the DIMM slots to 2-3, reduces the motherboard width from the horizontal, reduces the total area by about 0.92 square inches, and is more compact than the ATX standard motherboard structure. In accordance with the Micro ATX Standard, the board should also integrate graphics and audio processing capabilities.
