What Does a Motherboard Actually Do in a PC?

Before we dive in, let’s look at what a motherboard does. Think of a city. You have homes (your CPU), power plants (your power supply), and factories (your graphics card). The motherboard is like the roads and power lines of a city, connecting everything. Without it, you just have a bunch of separate buildings.

The motherboard is a big circuit board (PCB) with a few key jobs:

• It Holds Your Parts: The motherboard’s main job is to hold all the key parts of your computer. This includes the CPU, the memory (RAM), and cards like your graphics card.
• It Gives Power to Parts: The motherboard gets power from your power supply (PSU). It then sends that power to the CPU, RAM, and other parts plugged into it.
• It Lets Parts Talk: This is its most important job. The motherboard has paths called “buses” that let all the parts talk to each other. When you move your mouse, the signal goes through the motherboard to the CPU. The CPU then tells the graphics card to move the cursor on your screen. This all happens instantly, thanks to the motherboard.

In short, everything you do on your PC uses the motherboard. That’s why picking a good one is so important for a fast and stable computer, and a key part of learning how to pick a motherboard.

The First Big Decision: Choosing Your CPU Socket (Intel vs. AMD)

First, you need to pick your processor when building a PC. Are you using Intel or AMD? Your CPU choice narrows down your motherboard options. The CPU has to fit a specific “socket” on the board. You can’t put an AMD CPU in an Intel motherboard, or an Intel CPU in an AMD board.

The CPU socket is the part on the motherboard that holds the CPU. It has a special pin design that must match the CPU. Think of it like a key and a lock. Only the right key (CPU) fits the right lock (socket).

What Are the Current Sockets for Intel and AMD?

CPU sockets change every few years. Right now, these are the main sockets you will see:

• For Intel: The main socket for new Intel consumer CPUs (like 12th, 13th, and 14th Gen) is LGA 1700. “LGA” means the pins are on the socket, not the CPU.
• For AMD: The main socket for the newest AMD Ryzen CPUs (7000 series and up) is AM5. With AM5, AMD also uses an LGA design, so the pins are on the socket. For older Ryzen 5000 CPUs, you need an AM4 socket.

What Happens If I Choose the Wrong Socket?

It just won’t work. The CPU will not fit in the wrong socket. Forcing it will break the tiny pins on the socket or CPU. This can ruin expensive parts. Checking the socket is the most important step.

How Do I Know Which Socket My CPU Needs?

This is easy to find. The product page or box for a CPU will clearly list the socket it needs. For example, an Intel Core i7-14700K needs an LGA 1700 socket. An AMD Ryzen 7 7800X3D needs an AM5 socket. Always check this before you buy a motherboard.

How to Pick a Motherboard: Understanding Chipsets

Once you know your socket, you need to pick a chipset. If the motherboard is the city’s road system, the chipset is the traffic control. It’s a set of chips on the board that decides your PC’s features.

What Features Does a Motherboard Chipset Control?

The chipset controls many of the motherboard‘s features, like:

• How many USB ports you get and how fast they are.
• How many fast M.2 drives you can use.
• The number of SATA ports for other drives.
• If you can “overclock” your CPU and RAM to make them run faster.
• The version of PCIe slots, which is key for your graphics card.

Intel and AMD both have different chipsets. They usually come in high-end, mid-range, and budget options.

What Are the Main Differences Between High-End and Budget Chipsets?

Usually, pricier chipsets have more “lanes” for data. Think of these as highways. More lanes mean more data can move at once. This lets you use more high-speed parts at the same time.

• High-End Chipsets (Intel Z-series, AMD X-series): These have the most PCIe lanes and USB ports. They also have the newest tech and let you overclock your CPU and RAM. They are for users who want the best possible performance.
• Mid-Range Chipsets (Intel B-series, AMD B-series): This is the best choice for most people, especially gamers. They have a good mix of features and price. You get lots of ports and can often overclock your memory.
• Budget Chipsets (Intel H-series, AMD A-series): These are for simple PCs. They have fewer features and ports. They also don’t let you overclock. They are great for an office PC or a simple computer for web browsing.

Which Intel Chipset is Right for Me? A Guide for LGA 1700

For Intel’s LGA 1700 socket, there are three main chipsets:

• Z790: This is the top chipset. It’s for people who want the very best. It lets you overclock the CPU and RAM. It also has the most ports for USB and storage.
• B760: This is the most popular choice. It has great features for the price. But you can’t overclock your CPU with it. You can still overclock your RAM, which helps in games.
• H710: This is the basic option. It has the fewest features and no overclocking. It’s made for cheap PCs where cost is the top priority.

Which AMD Chipset Should I Choose? A Guide for AM5

For AMD’s AM5 socket, the choices are similar:

• X670E and X670: The “X” chipsets are for high-end builds. The “E” in X670E means “Extreme.” It promises a PCIe 5.0 slot for both the graphics card and a fast M.2 SSD. These are for users who want top performance.
• B650E and B650: This is the most popular pick for gamers and most users. The “E” version also promises a PCIe 5.0 slot for the graphics card. The B650 boards offer a great mix of features and price.
• A620: This is the budget chipset for AM5. It gives you what you need for a modern Ryzen PC but has fewer features to keep the cost low.

How to Pick a Motherboard Based on Size: Form Factors Explained

After you pick a socket and chipset, you need to pick a size. Motherboards come in standard sizes called “form factors.” The motherboard’s size decides which PC cases it fits in and how many slots it has.

The three main sizes you will see are ATX, Micro-ATX, and Mini-ITX.

What is an ATX Motherboard? (The Standard Choice)

ATX is the full-sized standard. It measures 12 x 9.6 inches. Its large size means it has the most features and slots. You will usually find four RAM slots and many PCIe slots.

• Who is it for? ATX is best for most people, especially if it’s your first build. It gives you lots of room and makes future upgrades easy. You need a mid-tower or full-tower case for an ATX board.

What is a Micro-ATX (mATX) Motherboard? (The Compact All-Rounder)

Micro-ATX is a bit shorter than ATX, at 9.6 x 9.6 inches. It’s a great middle option. It often has four RAM slots like ATX boards, but fewer PCIe slots. This is fine for most people who only use one graphics card.

• Who is it for? mATX is great for builders who want a smaller PC but still want good features. They fit in smaller mATX cases and are often a bit cheaper than ATX boards.

What is a Mini-ITX Motherboard? (For Tiny Powerhouse PCs)

Mini-ITX is the smallest size, at just 6.7 x 6.7 inches. These boards are for very small PCs. To be this small, they have fewer features. You only get two RAM slots and one PCIe slot for a graphics card.

• Who is it for? Mini-ITX is for people who want the smallest PC they can build. Building in a Mini-ITX case is tricky because it’s small. But you get a tiny PC that is still very powerful.

Are There Other, Larger Motherboard Sizes?

Yes, for very powerful PCs, you might see E-ATX boards. They are even bigger than ATX boards. They are made to hold the most powerful parts but are too much for most people.

How to Pick a Motherboard: What Key Features and Ports Should I Look For? 🤔

Now for the fun part: the special features. Here, you need to think about how you will use your computer.

How Many RAM Slots Do I Need?

Most ATX and mATX boards have four RAM slots. Mini-ITX boards have two. For most people, two slots are fine for 16GB or 32GB of RAM. That’s plenty for games and daily tasks. But, four slots let you add more RAM later without swapping your current sticks.

Should I Choose a DDR4 or DDR5 Motherboard?

This is a big decision. For the newest CPUs, you can pick a motherboard that uses older, cheaper DDR4 RAM or newer, faster DDR5 RAM. You can’t mix them. A DDR5 board only takes DDR5 RAM. DDR5 is faster and better for the future. But DDR4 is a good value for cheaper builds.

What Kind of PCIe Slot Do I Need for My Graphics Card?

The PCI Express (PCIe) slot is for your graphics card. You want the top slot to be a PCIe x16 slot. This gives it the most speed for the best performance.

Is PCIe 5.0 Necessary for My Motherboard?

You should also check the PCIe version. PCIe 5.0 is the newest and fastest, then PCIe 4.0. A PCIe 4.0 graphics card works in a 3.0 slot, but it’s best to match them. A PCIe 4.0 slot is fine for today’s graphics cards. PCIe 5.0 is more for future-proofing.

Why Are M.2 Slots So Important for Storage?

Fast storage uses the M.2 slot. This tiny slot holds a super-fast NVMe SSD. These drives are much faster than old hard drives. This means your PC starts up and loads games very quickly. Try to get a motherboard with at least two M.2 slots.

Do I Still Need SATA Ports?

Yes. You still need SATA ports for regular SSDs and large hard drives. These are great for storing lots of photos, videos, and files. Most boards have at least four SATA ports, which is enough for most people.

How Do I Know How Many USB Ports I Need?

First, look at your desk. Count how many USB things you use. Make sure the motherboard you pick has enough ports for your keyboard, mouse, headset, and other gear. It’s good to have one or two extra ports for the future.

What Kind of USB Ports Should I Look For?

Speed matters too. Look for a mix of USB types. This includes fast USB 3.2 Gen 2 ports and at least one USB Type-C port for new devices. A built-in I/O shield is also a great feature. It’s a metal plate that makes putting the board in the case much easier. For more information on the technical specifications of PCBs, you can review materials like those provided by Stanford University’s CS107e course.

Do I Need Onboard Wi-Fi and Bluetooth?

Many motherboards now have Wi-Fi and Bluetooth built-in. This is very handy. It saves you from buying a separate Wi-Fi card. If your PC is far from your router, getting a motherboard with Wi-Fi is a great idea. It often costs just a little more and is very handy.
