How to choose a motherboard
Chipset, form factor ATX/mATX/ITX, VRM, connectivity — the complete guide to picking the right motherboard for your CPU and build.
What a motherboard does
The motherboard is your PC's backbone: it connects CPU, RAM, storage, GPU, and peripherals. It doesn't generate performance on its own, but determines what you can connect and how.
Going too cheap can limit your CPU (weak VRM). Going too expensive for a basic build wastes money.
Socket compatibility: the first priority
Every CPU generation uses a specific socket. Your motherboard must match your CPU's socket — this is non-negotiable.
Intel LGA1700: 12th, 13th, 14th Gen Core. Z690/B660/H610 chipsets (12th gen), Z790/B760/H770 (13th, 14th).
AMD AM5: Ryzen 7000 and future generations. X670E, X670, B650E, B650, A620 chipsets.
Selects automatically checks socket compatibility. Never ignore a red warning.
Chipset: what actually changes
The chipset manages connections between CPU and peripherals. High-end chipsets (Z790, X670E) offer more PCIe lanes, allow CPU overclocking, and have more robust VRM.
Entry-level chipsets (H770, B760, B650, A620): no CPU overclocking, reduced connectivity, low price. Perfect for standard builds.
Mid-range chipsets (B760, B650): best value. XMP/EXPO support, enough M.2 slots, often 2.5G Ethernet.
Form factor: ATX, mATX, or ITX
ATX (305×244mm): standard size. 7 expansion slots, more M.2 and SATA ports. Recommended for most builds.
Micro-ATX (244×244mm): more compact, 4 slots. Good compromise for compact mid-tower cases.
Mini-ITX (170×170mm): most compact. 1 PCIe slot, 2 RAM slots. Ideal for SFF but pricier for equivalent features.
Check your case supports your chosen form factor. ATX in an mATX case is impossible.
VRM: critical for powerful CPUs
The VRM converts 12V power to precise CPU voltage. Weak VRM on a powerful CPU → overheating, throttling, instability.
For Core i5 or Ryzen 5: basic VRM is fine. For Core i9 or Ryzen 9, aim for at least 12+2 phases with quality MOSFETs.
Storage: M.2 and SATA
NVMe SSDs (M.2 PCIe) are 5–10× faster than SATA. Check the number of M.2 slots and their version (PCIe 4.0, 5.0).
If you have multiple drives, count available SATA ports. mITX boards often have only 2–4.
Network and audio connectivity
Ethernet: 2.5G has become standard on mid-range and high-end boards.
Wi-Fi: optional if you're using wired. Boards with Wi-Fi 6E include an M.2 Key-E module. Don't pay for it if you don't need it.
Onboard audio: Realtek ALC4080 codec provides decent sound for speakers or standard headsets.
