Investigate

Inspect an unsafe GPU-installation proposal

A technician proposes reusing a spare modular PSU cable for a GPU swap. The parts list also leaves uncertain radiator clearance. Use the cable compatibility and fit records to revise the installation plan before accepting the PC.

Decision 1

A cable that physically fits

The existing modular PSU is model P. A spare cable came from model Q of the same brand. No manufacturer chart confirms Q's cable is compatible with P.

Lesson notes

Use this checklist to prepare for the final quiz.

Key ideas

  • Major upgrades affect the whole system.
  • Expansion cards need slot, clearance, cable, and service checks.
  • Power planning includes wattage, connectors, quality, and headroom.
  • Airflow is a planned path, not just more fans.
  • Validation proves the upgrade is stable.

Check your understanding

  • Can you explain PCIe slots as parking spaces with roads?
  • Can you explain PSU headroom as a budget?
  • Can you describe intake and exhaust airflow?
  • Can you name four post-upgrade validation checks?
