How do I choose the right parts for my first PC build?

Start with your budget and what you want the computer to do. Gaming, video editing, schoolwork, and general browsing all require different parts. If gaming is the goal, also decide what resolution and performance level you want. Those details will narrow down the CPU and graphics card, which usually take up most of the budget.

A typical build includes a case, power supply, motherboard, CPU, CPU cooler, memory, storage, and possibly a dedicated graphics card. Choose the CPU and graphics card first, then select compatible memory and a motherboard with the ports and features you need. After that, choose storage, the case, cooling, and the power supply. Check that the motherboard and graphics card fit the case and that the power supply has enough capacity and the right connectors.

A good process is to make a complete parts list with a compatibility-checking tool, then review the list from start to finish. Confirm the socket, memory type, motherboard size, graphics-card length, cooler clearance, storage connections, and power requirements. Compare the total price against your budget, and have someone experienced check the list before ordering.

Look at current completed builds and component lists for the kind of system you want, then use them as examples rather than copying blindly. Software and games often publish recommended hardware requirements, which can help you estimate the CPU, memory, and graphics performance you need. Watching a full beginner build guide can also make the assembly and operating-system installation much less intimidating.
