Complete PC parts checklist before buying
Run through every compatibility, clearance and power check before paying for your components.
Check parts in PCNavo →Quick answer: PC build checklist
Before buying, verify CPU socket and BIOS support, DDR generation, motherboard and case size, GPU clearance, PSU wattage and connectors, cooler fit, storage slots and the exact model code of every component.
- CPU socket and BIOS
- DDR4 or DDR5 memory
- GPU and cooler clearance
- PSU capacity and connectors
- Case and motherboard size
- Storage slots and lane sharing
Verify the core platform
Confirm that the CPU socket matches the motherboard and that the exact processor appears on the motherboard support list. Check whether a specific BIOS version is required. A matching socket alone does not guarantee support.
Confirm that the motherboard uses the selected DDR4 or DDR5 memory and that its size fits the case. Review the board manual for storage slots, expansion layout and front-panel connectors.
Check graphics-card fit and power
Use the dimensions of the exact graphics-card model, not only the GPU family. Confirm length, thickness and height against the case, including any reduction caused by a front radiator.
Check the recommended system power and required connectors. The power supply should provide the correct native cables and sensible headroom for the complete build.
Confirm cooling compatibility
Check CPU cooler socket support and mounting hardware. For air coolers, verify height and memory clearance. For liquid coolers, verify radiator size, thickness, fan position and clearance around the motherboard.
Review whether the processor includes a usable stock cooler. Higher-power processors may need a stronger solution to sustain performance without excessive noise.
Review storage and connectivity
Confirm that every NVMe drive uses a supported M.2 slot and that installing it does not disable another required port. Count the SATA connections, USB headers, display outputs, network features and expansion slots you actually need.
Remember that a processor without integrated graphics may require a discrete graphics card before the system can display an image. Motherboard video ports do not create graphics capability by themselves.
Final checks before payment
Compare exact product codes, warranty coverage and return rules. Save a copy of the final parts list and verify every component is compatible.
Plan for an operating system, monitor cable, network connection and basic tools. After assembly, update the BIOS only when necessary, enable the supported memory profile and monitor temperatures during initial testing.
- Matching CPU socket and BIOS support
- Correct DDR generation and capacity
- GPU clearance and power connectors
- PSU capacity and quality
- Case, cooler and radiator clearance
- Storage slots and lane sharing
- Exact model codes and warranties
How to use this guide
Start with your actual workload, monitor and total budget. Compare complete component combinations instead of judging one specification in isolation, because a more expensive part can force compromises elsewhere in the build.
Before purchasing, verify the full model code on the manufacturer website. Confirm motherboard support, BIOS requirements, memory generation, power connectors, physical dimensions and warranty terms for your country. Specifications and manufacturer support information can change after this article is updated.
