Build Compatibility Check
Verify three of the most common build-compatibility risks before you buy.
Quickly check three common build-compatibility risks: CPU/socket match, GPU clearance in the case, and PSU headroom for the GPU.

The three mistakes that stop a first boot
Scenario: you assembled a parts list and want a quick sanity check before checkout — will the CPU fit the board, will the GPU fit the case, will the PSU cope?
Example: AM5 CPU + AM5 board = OK; a 30 cm GPU in a 35 cm case = fits; a 650 W PSU vs a 320 W GPU = OK (needs ≥416 W). All three checks pass.
Boundaries: this covers sockets, GPU length, and PSU wattage only. It does NOT check cooler-vs-RAM clearance, PSU cable types, case form factor versus motherboard, or BIOS version requirements.
FAQ: what else should I verify? Cooler height versus RAM and case, that the PSU has the right PCIe connectors, and that the motherboard form factor fits the case. Use a full builder checklist for the rest.

Run the check above, then print this sheet and tick each item before checkout. Press Ctrl/Cmd + P to print.
- CPU socket matches the motherboard (e.g. AM5 CPU → AM5 board).
- GPU length is shorter than the case clearance (allow ~2 cm).
- PSU wattage is at least total load plus ~30% headroom (e.g. 320 W load → ≥416 W PSU).
- Cooler height clears RAM and the case (not covered by this tool).
- PSU has the correct PCIe power connectors for the GPU.
- Motherboard form factor fits the case (ATX / mATX / ITX).
