In computer design, microATX (sometimes referred to as μATX, uATX [1] or mATX) [2] is a standard motherboard form factor introduced in December 1997. [3] The maximum size of a microATX motherboard is 9.6 × 9.6 in (244 × 244 mm).
A 20 % shorter variant of the ATX form factor. Compatible with most ATX cases, but has fewer slots than ATX, for a smaller power supply unit. Very popular for desktop and small form factor computers as of 2017. Mini-ATX: AOpen: 2005 150 × 150 mm (5.9 × 5.9 in) Mini-ATX is considerably smaller than Micro-ATX.
ATX is the most common motherboard design. [2] Other standards for smaller boards (including microATX, FlexATX, nano-ITX, and mini-ITX) usually keep the basic rear layout but reduce the size of the board and the number of expansion slots.
Mini-ATX motherboards are a smaller form factor of the ATX motherboards. It typically uses surface-mount technology for component placement, solid state capacitors to ensure stable power delivery, and an 8-layer PCB design to increase durability and longevity. This design is aimed to provide a better overall performance and reliability compared ...
The ATX connector provides multiple wires and power connections for the 3.3 V supply, because it is most sensitive to voltage drop in the supply connections. Another ATX addition was the +5 V SB (standby) rail for providing a small amount of standby power, even when the computer was nominally "off".
