Your motherboard connects everything together. It determines which CPUs, RAM, and storage you can use, and provides expansion slots, USB ports, and networking.

Match the chipset to your CPU. AMD B650/X670 pairs with Ryzen 7000 (AM5). Intel B760/Z790 pairs with 12th–14th gen Core (LGA 1700). Higher-tier chipsets offer more PCIe lanes, USB ports, and overclocking support.
ATX is the standard size with the most expansion slots. Micro-ATX saves space while keeping most features. Mini-ITX is for compact builds but limits expansion. Make sure your case supports the form factor you choose.
Look for built-in Wi-Fi 6E or 7 if you need wireless. Check the number of M.2 slots for NVMe storage, USB-C headers for front panel ports, and whether the board has enough fan headers for your cooling setup.
The voltage regulator module (VRM) on a motherboard controls how much power your CPU receives. Boards with higher-quality VRMs and more power phases deliver cleaner, more stable power, which matters most for high-core-count or overclocked CPUs. Budget boards sometimes cut corners here, causing throttling under sustained load. If you are running a power-hungry chip, look for reviews that test VRM thermals — a board with a decent heatsink on the VRMs will handle demanding workloads much better.
When a new CPU launches on an existing socket, older motherboards often need a BIOS update to recognise it. Some boards have a USB BIOS flashback feature that lets you update the BIOS without a CPU installed — invaluable if you are buying a brand-new processor with a board that has been sitting on a shelf. Always check the manufacturer support page for the latest BIOS version and verify your target CPU is listed in the compatible processors table before purchasing.
Most modern motherboards include capable onboard audio and at least 2.5 Gigabit Ethernet, which is sufficient for the vast majority of users. Dedicated sound cards are rarely needed unless you are doing professional audio production. Similarly, built-in Wi-Fi modules on mid-range and higher boards perform well enough that a separate PCIe Wi-Fi card is unnecessary. Spending more on a board with better onboard features can actually save money compared to buying add-on cards later.
Think about what you might add to your system down the line. If you plan to install a capture card, a sound card, or additional NVMe storage, make sure the board has enough PCIe slots and M.2 connectors. Some budget boards share bandwidth between M.2 slots and SATA ports, which can disable certain connectors when an NVMe drive is installed. Reading the motherboard manual or specification sheet before buying reveals these shared-lane configurations and prevents unpleasant surprises during a future upgrade.
A motherboard is one of the hardest components to replace once a system is built, so reliability matters. Boards from well-known manufacturers typically offer better warranty support and more frequent BIOS updates. Look for reinforced PCIe slots if you plan to use a heavy graphics card, and check for sufficient heatsinks on M.2 slots and the chipset. A three-year warranty is standard, but some premium boards extend this to five years. Investing a little more in a reputable board can save significant hassle if something fails.
It is tempting to save money on the motherboard and spend more on the CPU or GPU, but going too cheap can limit your build. A motherboard that lacks USB BIOS flashback, has a weak VRM, or only has one M.2 slot can cause frustration later. Aim to spend roughly 15–20% of your total build budget on the motherboard. This usually lands you in the mid-range, where you get solid power delivery, adequate connectivity, and a reliable feature set without paying for unnecessary premium extras.
