DFI's embedded Mini-ITX motherboard (measuring to only 170mm x 170mm) is designed with a variety of I/O connectors for low power solution with passive cooling and DC input features and for desktop solution with high performance. GIGABYTE Thin Mini-ITX motherboards are designed to revolutionize the DIY PC industry, offering DIY users the opportunity to build their own All-in-One PC. All-in-One PCs are becoming a very popular choice for many of today’s consumers, offering a space-saving, more integrated PC experience that doesn’t compromise on performance and features.
ATX motherboard size comparison; rear is on left.microATX (sometimes referred to as μATX, uATX[1] or mATX)[2] is a standard for motherboards that was introduced in December 1997.[3] The maximum size of a microATX motherboard is 9.6 × 9.6 in (244 × 244 mm). The standard ATX size is 25% longer, at 12 × 9.6 in (305 × 244 mm).
Currently available microATX motherboards support CPUs from VIA, Intel or AMD.
Backward compatibility[edit]
microATX was explicitly designed to be backward-compatible with ATX. The mounting points of microATX motherboards are a subset of those used on full-size ATX boards, and the I/O panel is identical. Thus, microATX motherboards can be used in full-size ATX cases. Furthermore, most microATX motherboards generally use the same power connectors as ATX motherboards,[4] thus permitting the use of full-size ATX power supplies with microATX boards.
microATX boards often use the same chipsets (northbridges and southbridges) as full-size ATX boards, allowing them to use many of the same components. However, since microATX cases are typically much smaller than ATX cases, they usually have fewer expansion slots.
Expandability[edit]
Most modern ATX motherboards have a maximum of seven PCI or PCI-Express expansion slots, while microATX boards only have a maximum of four (four being the maximum permitted by the specification). In order to conserve expansion slots and case space, many manufacturers produce microATX motherboard with a full range of integrated peripherals (especially integrated graphics), which may serve as the basis for small form factor and media center PCs. For example, the ASRockG31M-S motherboard (pictured right) features onboard Intel GMA graphics, HD Audio audio, and Realtek Ethernet (among others), thus freeing up the expansion slots that would have been used for a graphics card, sound card, and Ethernet card. In recent years, however, it is common even for ATX boards to integrate all these components, as much of this functionality is contained in the typical northbridge/southbridge pair. With the 'must-have' functions already present on the motherboard, the need for having many expansion slots has faded, and adoption of microATX has increased even to be used in ATX cases.
In the DIY PC market, microATX motherboards in general are favored by cost-conscious buyers, where cost savings for the equivalent feature sets outweigh the added expandability of extra PCI/PCI Express slots provided by the full ATX versions. Since 2006, dual-GPU configurations became possible on microATX motherboards for high-end enthusiast gaming setups, further reducing the need for full ATX motherboards.[5]
In addition, some microATX cases require the use of low-profile PCI cards[6] and use power supplies with non-standard dimensions.[7]
Compared to Mini-ITX, microATX motherboards have a maximum of four expansion slots and four DIMM slots, as opposed to the single expansion slot and two DIMM (or SO-DIMM[8]) slots on Mini-ITX motherboards. This means that microATX allows dual-graphics card and quad-channel memory configurations.[9]
