Gaming PC Power Supply Guide | PSU Sizing & Quality
Plan a gaming PC power supply around the configured CPU, GPU, connectors, efficiency and upgrade headroom.
The PSU is a system requirement, not a cosmetic upgrade.
1
Size the PSU after the CPU and GPU are known.
2
Check the exact connectors required by the configured graphics card.
3
Leave sensible headroom instead of sizing to the edge.
4
Choose quality and protection features before chasing wattage alone.
Configuration rule: exact compatibility, stock and final prices should be validated by the live WooCommerce configurator, not hard-coded into this static guide.
Use the guide with a real build
Once the requirement is clear, move to the bundle configurator. That lets you compare the current compatible choices instead of making a list from outdated or incompatible parts.
