PC builder.

Build a PC online

Select components from the local catalog or choose a hardware region in the schematic. Add, replace and remove parts to explore a custom PC build. The PC builder simulator shows assembly regions and illustrative clearance guides; it is not a scale-accurate physical model.

PC parts compatibility

Encoded checks cover CPU socket, motherboard mounting, memory generation/slots/capacity, cooler mounts and height, GPU clearance, PSU format/load/headroom/guidance and fan mounts. Failures and warnings are counted separately. Missing related parts leave a check unverified; a passing result covers only these rules.

Power and score estimates

Estimated load combines component power allowances and overhead. Recommended PSU capacity accounts for 30% load headroom and GPU manufacturer guidance. The Build Balance Score averages five editorial heuristics when core parts are present. Compatibility failures hold the score; warnings leave it provisional. These are not measured benchmarks.

Share your build

After selecting a component, copy a build link to preserve selected IDs and the build name in the URL. No account or database is needed. Continue to Rate My PC with the same selected hardware for a partial rating when only CPU, GPU and RAM are known.

Component data limits

Prices, load allowances and performance indices are estimates. LAB Reference parts are sample fixtures; GPU geometry is illustrative. Verify exact models, BIOS, memory support, connectors and clearance before purchasing. The finite catalog does not represent every available component.
