Our free PC build compatibility checker searches from Koukan's real parts database — the same one that powers our marketplace listings. Simply search for your CPU, motherboard, GPU, RAM, PSU, case, cooler, and storage and add them to the interactive 3D view above.
The checker validates CPU socket compatibility with your motherboard, ensures your RAM DDR type matches, checks GPU clearance in your case, verifies your PSU has enough wattage for your build, and confirms your CPU cooler fits in both the case and the CPU socket.
All checks run instantly in your browser — no account or personal information required. Whether you're a first-time builder or an experienced enthusiast, use this tool to avoid costly compatibility mistakes. Use the 3D View to see your parts positioned inside a virtual PC case with zoom and pan, or Simplified View for a quick list overview.
