Motherboard

The motherboard is not a simple multilayer printed circuit board on which you install the main components of a personal computer (CPU, memory controller and the actual RAM, boot ROM, a base input-output interfaces). Typically, the motherboard includes connectors for additional controllers for connecting traditionally used bus USB, PCI and PCI-Express.Ot English. motherboard, sometimes abbreviated as MB or word mainboard - the main board.

Form factors of motherboards:

Form Factor AT

Form Factor LPX

Form Factor ATX

Form factor Micro-ATX

NLX form factor

Form Factor EATX

BTX Form Factor

Form factor mBTX

Form factor mini-ITX

Form Factor SSI EEB

Form Factor SSI CEB

nonstandard

Maternal Plataforma factor determines dimensions, mounting holes, power connectors of the motherboard, and even cooling requirements. When selecting devices for companies to remember that the housing company must support the form factor motherboard. Possible form factors motherboards: ATX, mATX, EATX, BTX, mBTX, mini-ITX, SSI EEB, SSI CEB, nonstandard.

ATX (Advanced Technology eXtended) - one of the most popular formats, PC motherboards, is ideal for the construction of a home computer. ATX board dimensions are 30.5 x 24.4. cm and 7 expansion slots support. The main connector for the power supply to a standard ATX motherboard can have 20 or 24 pins. Almost all of the latest models of motherboards have a 24-pin connector.

mATX (micro ATX) - A few drops of the size of a standard ATX. Suitable for constructing office computers when not needed many slots for system expansion. MATX boards have dimensions of 24.4 x 24.4 cm and 4 expansion slots support. The main connector for the power supply to the standard mATX motherboard has 20 or 24 pins. Almost all of the latest models of motherboards have a 24-pin connector. EATX (Extended ATX) motherboards differ from ATX size (up to 30.5 x 33.0 cm), used mostly for servers.

BTX (Balanced Technology Extended) - a new standard that comes to replace the ATX. In the development of this form factor a lot of attention was paid to the efficient cooling of the on-board components. BTX is ideal for building miniature computers. BTX motherboards have dimensions 26.7 x 32.5 cm, and 7 expansion slots support.

mBTX (micro BTX) - a smaller version of BTX. Dimensions of such boards are 26.7 x 26.4 cm mBTX support 4 expansion slots.

mini-ITX - form factor for motherboards investigated by VIA Technologies. Electrically and mechanically compatible with the form factor ATX. Motherboard mini-ITX have small dimensions (17 x 17 cm).

SSI EEB (Server Standards Infrastructure Entry Electronics Bay). The motherboard standard traditionally work to build servers. Connectors to enable feeding unit has 24 +8 contacts. Dimensions of such boards compose 30.5 x 33.0 cm

SSI CEB (SSI Compact Electronics Bay). Motherboard of the standard traditionally used to build servers. Connectors for the power supply are 24 +8 contacts. Dimensions of such boards are 30.5 x 25.9 cm

Form factor motherboard - standard defining the size of the motherboard for the personal computer, the place of its attachment to the body, placing it on the bus interfaces, I / O, CPU socket (if available), and slots for RAM, and another kind of Connector for connecting the board pitaniya.Materinskaya

Form factor is a recommendation. Specification form factor describes the mandatory and optional components. But the vast majority of manufacturers prefer to abide by the specification, since the price of compliance with existing standards are compatible motherboard and standard equipment of other manufacturers.

Obsolete: Baby-AT; Mini-ATX; full-size boards AT; LPX.

Modern: ATX; microATX; Flex-ATX; NLX; WTX, CEB.

Insertion: Mini-ITX and Nano-ITX; Pico-ITX; BTX, MicroBTX and PicoBTX
