Different Types of Motherboard Form Factors You Should Know

Knowing the types of motherboard is handy for pretty much anyone who uses a computer. Well, the motherboard is the main module or the component that connects all the other components of a computer.

It’s true that many individuals consider CPU and RAM to be the most important parts of a motherboard. However, all the other components of your computer are connected to the same component. For instance, components like PCI slots, capacitors, USB ports, M.2 slots, and everything else are connected to the motherboard. So, without a motherboard, your computer cannot perform at all. Below, we discuss the motherboard form factors that are available in the market today. We introduce the different types of motherboard options so you can decide which one is better.

In fact, different types of motherboard options are used to solve different types of problems. So, those motherboards become a crucial part of further advancements. There is no shortage of motherboard form factors to consider. But the thing is that not all those products retain their popularity and consistency. Also, the other options are slow in adoption.

With that said, this article explains aspects like form factor, its importance, and different types of motherboard.


Introduction to motherboard form factors 

In simplest terms, motherboard form factors represent the specifications of a given motherboard variety. It includes options like the type of the board, its dimensions, the availability of the ports, power supply, etc.

It also offers all the necessary details. As a result, anyone can check if that product is compatible with the requirements of the consumer. You can have different types of form factors, and they are designed to serve different purposes. For instance, a full-sized motherboard will have a large number of PCIe slots compared to a mini-ATX board. That’s just a simple example for your information.

Generally, motherboard form factors differ depending on the advancements of the technology. When computer technology gets advanced, the manufacturers of motherboards tend to change the standards of their products. The standards of a motherboard assure the size as well as the layout.

It is true that the changes in form factors take place gradually. However, the evolvement is regular. In 1995, ATX boards were introduced along with their standards. Twelve years later, ATX boards received an update. Those boards are known as ITX as of today, and they are much smaller than their ancestors. Also, they maintain their own standards.

The requirement for ITX boards emerged because the changes took place related to the demand for the computer. For instance, many computer users wanted to use smaller, compact systems with more portability.

Form factors are generally based on aspects like subsets and supersets. Form factors determine to which requirement they cater. To make it clearer, a desktop computer will have more connection ports and sockets compared to a multimedia system. Also, multimedia systems don’t have the ability to add extra cards. However, you can expect the same with a desktop PC. That is because the types of motherboard used in these two systems are different as they cater to different requirements.

With a small motherboard, you can expect better convenience in terms of portability. However, they may lack additional ports and slots that are available in bigger versions.


Components included in all types of motherboard 

Regardless of the type of motherboards, they have several important, must-have components. Each of those components is assigned a different task. You can read the below section and learn those components.

01. CPU Socket

CPU Socket

CPU Socket is a must-have component no matter what types of motherboard we are talking about. It is the socket where your CPU is mounted. Well, Intel and AMD are the main manufacturers who make processors. They are installed on different sockets. Also, you cannot use those processors interchangeably on sockets.

A CPU socket is made with hundreds of pins or pinholes to establish a connection with the processor. Both of the aforementioned companies (AMD and Intel) have released different types of sockets over the past period. Those sockets support a specific generation of processors.

02. VRM

VRM

VRM is the shortened form for Voltage Regulator Module. It regulates the voltage received from the power supply and offers the correct voltage to the CPU. The regular power supplies offer a +12V DC EPS power connecter. The VRM converts that voltage to a smaller value (between 1.1V to 1.4V). A VRM has three main components called Choke, Capacitor, and MOSFET. Those three components ensure that there is a regular, stable, and controller power supply to the motherboard.

03. DIMM Slots

DIMM Slots

Dual In-Line Memory Module (often known as DIMM) slots are essential to install your RAM sticks to the motherboard. RAM sticks have volatile memory, and they store data temporarily. Different types of motherboard can have a different number of DIMM slots. For instance, some motherboards have 2 DIMM slots while another may have 8 of them.

Also, here is the full PCI vs. PCI Express comparison for your reference.

04. PCI Slots or Expansion Slots

PCI Slots or Expansion Slots

PCI is the abbreviation for Peripheral Component Interconnect. Those slots are there to connect peripheral devices to the motherboard directly. The most common type of PCI slots is PCI-E X1 and PCI-E X16. When it comes to older types of motherboard, you can find AGP slots. Those are used to install video cards. However, they are now being replaced by faster PCI-E slots.

05. SATA

SATA

SATA stands for the term Serial Advanced Technology Attachment. Basically, it is an interface that builds a connection between the motherboard and a storage device (SSD). Compared to other components, SATA or SSD drives are connected to the motherboard with 7 pins.

06. M.2.

M.2.

This could be considered one of the latest inclusions of modern-day motherboards. This module can be used to establish Wi-Fi, SSD, Bluetooth, and other types of connections. This module lets PCI, USB, and SATA buses get through. With that said, pretty much all the Intel and AMD motherboards come with at least a single M.2 slot.

07. Audio

Audio

Even if you check different types of motherboard, they all have a dedicated audio section. This specific section is located next to the audio jacks. You can easily identify it by looking at the PCB circuit along with several capacitors. In addition to that, you can see high-end motherboards with more components in the same section.

08. CMOS battery

CMOS battery

CMOS is another non-volatile memory that comes with any type of motherboard. You can find it easily because it has a round shape with silver color. It is responsible for storing all the information related to hardware. For instance, it has information related to CPU, RAM, and Disk Drives. In addition to that, the same module stores the correct time and date as well.

09. Headers

Headers

Basically, headers are a sort of connectors that appear in the form of pins. They are used to connect various types of peripherals to the motherboard. For instance, it connects components like chassis fans, CPU fans, USB, audio (front panel), and so on. Each of these connectors comes with different configurations. Also, they work at a specific voltage.

10. Power Connectors

Power Connectors

The motherboard cannot work unless you provide a power supply. There are different types of power connectors assigned for different components. Some of those components don’t even want additional power connectors. They draw power from the slots themselves. You can find two main power connectors, namely ATX and EPS. The pin configuration will vary on different types of motherboard. Well, the ATX is designed to provide power to different sections of the motherboard. On the other hand, EPS is dedicated to providing power to the VRM unit we explained earlier on.
