What is LPX?(What is, Concept and Definition)

LPX ( Low Profile eXtension ) is a motherboard form factor developed by Western Digital in 1987, when it was manufacturing motherboards, which was used at the end of the 1980s and throughout the 1990s.An LPX motherboard is 9 "wide x 13" deep, uses a riser card, and has a different location for the video, parallel, serial, and PS/2 ports compared to Other motherboards.Below is a picture of a Packard Bell LPX motherboard, as you can see, this motherboard has big brown riser card slot.Using riser card allowed expansion cards to be installed Parallel to the motherboard, so the LP in the LPX stands for "low profile." The low profile allowed computers using this motherboard to be much thinner than computers using a Baby-AT motherboard.

The LPX motherboard was not the only motherboard that had a riser card.The NLX motherboard also has a riser card, however the NLX motherboard is actually connected to the riser card instead of having the card vertical on the motherboard.
