Buying Guide

Match CPU socket and architecture

Confirm the board supports your processor family—examples here include ARM-based single-board designs and Intel LGA1150 and AMD AM3+ sockets—to avoid compatibility issues

Choose the right form factor

Micro ATX and single-board form factors determine case fit and expansion slot availability; pick a board that fits your case and expansion needs

Check supported memory type and speed

Boards in this price band use DDR3 or integrated memory on SBCs; ensure the board’s RAM type and max speed match your modules

Look for integrated connectivity

Built-in features such as Wi‑Fi on single‑board computers or onboard audio and SATA ports reduce the need for extra cards or adapters

Consider diagnostic and testing tools

A PSU and motherboard diagnostic tester can save time troubleshooting power and POST issues when assembling or repairing budget systems
