The DTX format is a form factor for motherboards ( mainboards) of microcomputers, which was presented by AMD in early 2007. DTX motherboards are equipped with 244 mm x 203 mm significantly smaller than the motherboards in the ATX format, but they are backward compatible with it. The Mini- DTX format is 170 mm × 203 mm an even smaller version (lower depth). DTX is intended for use both in the normal PC as well as for use in the living room computer.

In contrast to the mini -ITX format DTX provides two expansion slots, each one expected to PCI and PCI- Express connector. In addition, in the standard installation of a ExpressCard slot is provided. This is probably (like some mini- ITX boards ) placed at the bottom.

As an advantage over the standard ATX format with 6 or 4 slots significantly lower costs for the production of printed circuit boards are called, as a manufacturer of a standard AT board instead of 2 ATX motherboards 4 DTX or even 6 mini- DTX motherboards can cut. We follow here the trend toward fewer and fewer expansion cards in personal computers because on the one hand components such as disk controllers and network interfaces have become standard components and are consistently installed on the motherboard, on the other hand, expansion components are increasingly operated externally to USB ports and in many cases no longer available as a plug-in card are. So far, this development has hardly led to smaller PC cases, as the savings from the uATX format in this regard are hardly worth (6 cm in height at tower cases ).
