Build Compatibility Check

Verify three of the most common build-compatibility risks before you buy.

Estimates only. These calculators use typical component specifications and rough rules of thumb. They are for planning and education, not purchase advice. Verify every number against your parts’ official datasheets before buying or building.

Quickly check three common build-compatibility risks: CPU/socket match, GPU clearance in the case, and PSU headroom for the GPU.

Result

All checks pass
Socket matchOK
GPU clearanceFits (30/35 cm)
PSU headroomOK (650 W)
Three of the most common “it won’t post / won’t close” mistakes. Also verify the cooler clears RAM and the PSU has the right cables — this check covers sockets, GPU length, and PSU wattage only.
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.

Printable pre-build compatibility checklist

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).
