The fastest way to plan a PC build: decide your budget and what you want the PC to do, choose your graphics card and CPU first, then build the rest of the parts list around them and run it through a PC planner tool to confirm everything is compatible. That single workflow — plan, choose, verify — is what separates a smooth first build from an expensive return trip. You can do all of it online for free: our PC build planner lets you build your PC online, part by part, with live compatibility and price checks and nothing to install.
Step 1: Set a budget and define the goal
Before you pick a single part, answer two questions: how much can you spend, and what is the PC for? A 1080p esports machine, a 1440p high-refresh gaming rig, and a 4K video-editing workstation have very different parts lists. As a rough guide, entry 1080p builds start around $700-800, a strong 1440p build lands near $1,200-1,500, and no-compromise 4K systems run $2,000 and up.
Step 2: Choose the CPU and GPU first
These two parts define performance and consume most of the budget, so choose them before anything else. For gaming, weight spending toward the graphics card; for editing, rendering, or coding, prioritize the CPU. Pick the platform here too — AMD AM5 or an Intel socket — because it dictates your motherboard and memory choices in the next step.
Step 3: Build the rest of the parts list around them
With the CPU and GPU locked, fill in the supporting cast. Match the motherboard to your CPU socket, add DDR5 memory (16GB minimum, 32GB for multitasking), a fast NVMe SSD, a right-sized power supply, and a case that physically fits your GPU and cooler.
Step 4: Verify compatibility with a PC planner
This is the step that saves beginners the most pain. A PC parts calculator (also called a system builder or virtual PC builder) checks the four things that trip people up: CPU-to-motherboard socket, RAM type, total power draw vs. PSU wattage, and physical clearance inside the case. It also tallies the running price so you stay on budget. Our free PC planner does all of this live as you add parts — no account required.
Build your PC online with a free PC build planner
You do not need any software to plan a build — you can build your PC online, right in the browser. Our free PC build planner is a full virtual PC builder: search real parts, add them to a list, and watch it validate socket, RAM, wattage, and case fit while it totals live prices. Save or share the result, or start from one of our community buildsand customize it. When you are happy with the parts list, the planner links straight out to buy each component — the fastest way to go from “I want to build my PC” to a verified, ready-to-order build.
Not sure where to start? Use a proven build
If a blank parts list feels intimidating, start from a build we have already balanced and compatibility-checked, then tweak it. Our best value gaming PC is a great template, and you can browse all community builds for more ideas across every budget.
