What is a Motherboard?

First of all, you must know that what is a motherboard. I think you must have an idea about it in pictures, yet the definition is here;

“A motherboard is actually a printed circuit board that has the principal components with connectors of the device in which it is used. It allows the communication between the crucial electronic components equipped in it”.

Like in the case of a laptop motherboard, the components will be of a laptop. It is really an essential part of a laptop because it is holding and connecting the crucial components of a laptop together in one place. These components include the processor, connectors, RAM, graphics card and hardware components.

It’s the central communication hub and without it a laptop is nothing. That’s why understanding the motherboard size chart is really important. There are different names of a motherboard. It is also called a logic board, circuit board, mainboard, system board, and the planer board too. Also, read about the laptop screen size comparison chart.

Type of a motherboard – Motherboard Size Comparison Chart

There are many different types and each of them definitely varies in their sizes. That is what today’s topic is. We will guide you about the Motherboard Size Comparison Chart. The types are;

  • AT
  • Micro ATX
  • Extended ATX
  • Mini ITX
  • Pico ITX

So, these are some of the motherboard types which was developed a lot of years back. ATX standards were developed by the Intel while Mini ITX is a product of Via technologies. These models are still used in now a day laptops, yet they have modified a lot for sure according to the modern requirements.

Motherboard Size Comparison Chart

Here, you will get to know about the comparison of different sizes of the motherboard. You must know that there are different sizes and definitely a size matters a lot. It is really difficult to choose the proper size of a motherboard.

The purpose is to develop an understanding of these sizes so that you can select the accurate one if your laptop circuit board is dead and you are trying to replace it or due to any of the other reasons.

So, here is the Motherboard Size Comparison Chart for your people;

Motherboard size Height Width Official standard

I hope this chart has helped you in understanding the sizing. It tells you about the ideal height and width of a motherboard that is measured with great care. Almost all have their official standard sizes explained here, yet HPTX and XL-ATX might have some height and width with a slight difference.

These sizes of motherboards also vary on different laptops. This is because of the multiple standards of the processors and single processor motherboards. Each of these has slight modifications in its structure.

You can also measure the dimensions of your laptop system board yourself. You will be guided about in this article for sure.

Motherboard Form factors

Actually, the logic board form factors determine the physical sizes, feature or component placement, and general layout and also about the connectors and power supply. Different form factors of the laptop circuit boards are ATX, AT, baby ATX, Micro and Mini ATX, the Flex ATX, LPX, and Mini LPX and NLX.

Actually, the size and specifications (dimensions) of a motherboard is called as a form factor in technicians language. The AT form factor is the biggest and most older one. After that the baby AT gained so much popularity. So, a motherboard size is called as a form factor. 

Motherboard basic components

When you take out a motherboard from a laptop, you are so much confused that what is this complex circuit and what are its components. It looks like a hard thing to understand but it is not that much complex as you think. Once you will know about its components, you will understand the entire logic board circuit.

CPU socket

The processing unit of the laptop is equipped in its socket directly. The thing right next to it is the mounting points of the fans for the dissipation of heat. When a high-speed processor is working, it generates a lot of heat and for the dissipation of this heart, the fan mounting points are equipped in this circuit next to the CPU socket.

Card slots

There are different types of slots in a laptop main circuit. these slots are specifically designed for the specific components or either for the general expansions. Typical slots have their specific standards.

Modem Card Slot

This card slot for your connecting to any network either landline, ethernet, WIFI telephone line, etc. This is an older technology thing in some of the circuits to connect with the telephone line too.

Audio and video card slots

There is a small card slot for audio. It is the place where electrical signals are converted into audio signals. There are different types of ports found on the back depending upon the type of sound. Basically, 3.5 mm ports are for the speaker, microphone, recorder, and joystick.

Aside from the integrated graphics and the CPU slot, the video slot is located with the integrated video card in it. This goes to the high data slots including the ports for HDMI, display port and DVI which depends on the card.

Network card slot

NIC or the network interface card is placed in this slot. It allows connecting laptop via networks of different types like LAN, MAN, etc.

BIOS and CMOS

All of the motherboard information and settings are stored in the Basic Input Output System. This entire information can be easily accessed and modified using the BIOS mode. While CMOS is the battery which is responsible for keeping the entire data saved when the laptop is off.

Input & output ports

These input and output codes are located in the back with their color-coding. Different colors represent the different ports connections. Like pink for a microphone, green for speakers and headphones, ethernet network cable port is colorless. The keyboard one is purple, green for mouse and solid blue for the USB devices.

RAM slot

It is one of the most essential parts of a laptop’s entire internal circuit. RAM slot is a place where the RAM modules are placed. Some slots support the 32-bit bus while some support the 64-bit bus in it.

Cabinet connection

It is the area where you connect the power switch. Here’s the LED power indicator. The front audio and the USB port is also here. these connections are critical to controlling the operation of your system. 

Power connectors

The ATX connector is having at least 20 – 24 pin female connectors. Apparently, it is the larger connector among all. It utilizes the electricity to keep the motherboard running all the time when the laptop is ON. Every motherboard has special power connectors with them that gives power to the entire system. These power connectors use the power supplies too.  

Motherboard Size Differences

There are different motherboards and it is really difficult to pick up the one. However, you don’t have to get worried because I will tell you about different circuit boards of different sizes here. All of them come with new advancements or changes with time. Definitely, there sizes also varies and everyone has different capabilities for their work too. So here we go;
