Mini ITX Motherboards

Build a Smaller PC with the Right Mini-ITX Motherboard

A compact PC starts with a motherboard that gives you the features you need without taking up unnecessary space. Mini-ITX motherboards are suited to small gaming systems, home PCs, media setups, and compact workstations where case dimensions matter.

Choose according to your processor platform, budget, storage needs and connectivity rather than size alone. If you are considering a different form factor, browse all types of motherboards to see which layout works best for your build.

Choose Your Intel or AMD Mini-ITX Platform

Your processor socket is the first compatibility check. Intel Mini-ITX motherboards in the range include options using LGA1700 and LGA1851, while AMD Mini-ITX motherboards cover AM4 and AM5 platforms.

An AM5 Mini-ITX motherboard, for example, must still support the exact AMD processor you intend to install. The same applies to Intel boards, so always check the manufacturer’s CPU support list and any required BIOS version before ordering.

Mini-ITX Gaming Motherboards for Compact Setups

A Mini-ITX gaming motherboard can support a powerful small-form-factor system when the board, graphics card and case are chosen together. You should look at the power-delivery design, PCIe graphics slot, fan and pump headers, networking, and the connections required by your gaming setup.

Motherboard size does not determine which graphics card will physically fit. GPU length, thickness, and cooler clearance depend mainly on your case design and component layout, so check the graphics-card limits of your compatible PC case before completing the build.

Compare Mini-ITX & Thin Mini-ITX Before Buying

Standard Mini-ITX is commonly used for conventional compact desktop builds, while a Thin Mini-ITX motherboard is designed for slimmer, specialist systems where internal height and power arrangements can differ. Do not assume the two formats are interchangeable. The following details matter especially when replacing a board in an existing low-profile PC:

• Board dimensions and mounting points
• Power input and connector requirements
• DIMM or SO-DIMM memory support
• Available PCIe expansion
• CPU cooler mounting
• Chassis compatibility

Get the Memory, Storage & Connections You Need

Check the specification of each small form factor motherboard carefully, as compact dimensions can mean fewer expansion options than larger ATX designs.

Some boards support DDR4 while newer platforms may use DDR5. You should also confirm whether the board accepts standard desktop DIMMs or SO-DIMMs, along with its maximum supported memory capacity and speed.

Storage provision can differ too. Check the number and specification of M.2 slots, available SATA connections and rear USB ports before purchasing. Wi-Fi and Bluetooth are available on selected models, but they are not standard on every Mini-ITX board.

Match Your Board to Your Case, Cooler & Power Supply

Mini-ITX builds reward careful component matching. Before ordering, confirm that your case supports the motherboard mounting format and leaves enough room for your CPU cooler, RAM modules, and internal cables.

Check your chosen CPU cooling options against the case’s cooler-height or radiator limits as well as the motherboard socket.

You should also check what PSU format your case accepts and how much power the complete system requires. Mini-ITX does not automatically mean SFX. Some compact cases support other PSU formats, so use the case specification and total system requirements to select a suitable power supply .

Compare ASUS, ASRock, GIGABYTE & MSI Options

Laptop Outlet stocks Mini-ITX options from ASUS, ASRock, GIGABYTE, and MSI across different Intel and AMD platforms. Rather than choosing on brand name alone, you should look at the features that affect your particular build. Useful differences can include:

• CPU socket and chipset
• DDR4 or DDR5 support
• M.2 and SATA storage capacity
• Wired and wireless networking
• Rear and internal USB connectivity
• Fan and cooling headers
• Included antennas and accessories
• Board layout and connector positioning

This makes it easier to choose a board that fits both your hardware requirements and your budget without paying for features you will not use.
