White ATX is the most well-known and used form factor, there is also a non-standard proprietary form factor which falls under the name of LPX, and Mini-LPX. The LPX form factor is found in low-profile cases (desktop model as opposed to a tower or mini-tower) with a riser card arrangement for expansion cards where expansion boards run parallel to the motherboard. While this allows for smaller cases it also limits the number of expansion slots available. Most LPX motherboards have sound and video integrated onto the motherboard. While this can make for a low-cost and space saving product they are generally difficult to repair due to a lack of space and overall non-standardization. The LPX form factor is not suited to upgrading and offer poor cooling.
LPX (9.00" wide x 13.00" deep) Developed by Western Digital when making motherboards, which was duplicated by many other manufacturers and is no longer made by Western Digital.
The LPX motherboard riser card contains all of the expansion slots.
Placement of the video, parallel, two serial and PS/2 connections have changed locations.
Plantwiz. Thankx for your response.
Is there anyway to identify from a diagram wheather its a AT or Baby AT MOBO other then by its dimension and both AT and Baby AT MOBO does not come with PS/2 port ?
Ways to Identify between LPX and NLX
LPX and NLX - The only difference is they have raiser card.
LPX - The Raiser card located in the middle of the MOBO
NLX - The Raiser Card located on the side of the MOBO
Both LPX and NLX expension slots will be placed horizontally.
Is that Correct ?
Thank you very much for your responding. I am feeling much confortable to identitfy the type of Form Factors.
Right now I am just starting to study from Chapter 1 - MOBO.
Its a bit sticky on identify the type of Form Factors.
how often that Form factors questions appear on the exam ? Any idea ? Coz I am still worrying about if they put a diagram up. I was unable to tell wheather is XT/AT/Baby AT/ATX/LPX/NLX.
