Form Factor of Motherboard

Form Factor of Motherboard refers to its physical shape, layout and positioning of components on it. It also determines the type of system case it will fit into. Some motherboards that have the same function ability can be packaged into different form factors. The only major difference between such motherboards will be the form factor.

The Motherboard can be classified into three from factors:-

1. Obsolete Form Factor

2. Modern Form Factor

3. Proprietary form factor

 Obsolete Form Factor

Obsolete form factors consist of Advanced Technology (AT), Baby AT and Low Profile Extended (LPX) form factors. IBM computers used the AT form factor motherboards and the LPX fond factor was mostly used by Western Digital. The size of these motherboards was very large and was used in the earlier days. Nowadays this form factor is not used and is replaced by the ATX and micro ATX form factors.

Baby AT Form Factor

Baby AT Form Factor is very much similar to the original IBM XT motherboard structure. The baby AT form factor fits into most of the system cases. A baby AT motherboard is 8.5 inches wide and about 13 inches long. The length of baby AT motherboards is not fixed. It supports a maximum of 8 slots.

 Advanced Technology (AT) Form Factor

AT form factor is also known as the full-size AT form factor. This form factor matches the original IBM AT motherboard in structure and layout. This type of motherboard is very large and is about 12 inches wide and 13.8 inches long. The AT form factor is not used much by present-day motherboard manufacturers. This type of motherboard does not fit into most of the popular system cases and its size also makes installation and troubleshooting difficult. It supports a maximum of 7 slots.

Low Profile Extended (LPX) Form Factor

LPX and mini LPX form factors are used for small slim line or low profile cases. This form factor was developed by Western Digital, who no longer produces motherboards. However, many manufacturers have duplicated the LPX form factor. The LPX form factor has advantages like low cost and small size. However, it is difficult to upgrade or expand. These motherboards also exhibit cooling problems and as such the machine shut down automatically at times. It supports a maximum of 8 slots.

Modern Form factor and Proprietary Form Factor will be dealt in details in my next article.
