PC Part Picker & System Builder
PlanMyPC is a free online PC part picker and system builder. Choose a CPU, motherboard, memory, graphics card, storage, case, and power supply, and we automatically check that your parts work together, estimate your system’s power draw, and track prices as you go.
Whether you’re building your first gaming PC, upgrading an existing rig, or planning a high-end workstation, the builder keeps your parts list compatible and within budget from start to finish.
How the PC builder works
Add parts by category and let PlanMyPC handle the hard part. Here’s what you get with every build:
Compatibility checking
Every part you add is checked against the rest of your build in real time — CPU socket, RAM type, GPU clearance, and PSU headroom — so you catch conflicts before you buy.
Wattage estimation
As you pick components, PlanMyPC estimates total system power draw and recommends a power supply with enough headroom for stable, efficient operation.
Live price tracking
See current prices for each part and track how they move over time, so you can time your purchase and stay on budget.
Works for any build
From a budget office PC to a 4K gaming rig or a workstation, start from scratch or a template and customize every component to fit your needs.
