Learning Goals

Study Outcomes

  1. Identify key PC components -

    Accurately name and recognize functions of major parts like the motherboard, CPU, RAM, storage drives, and power supply within a computer build test environment.

  2. Apply proper mounting techniques -

    Demonstrate how to securely install the motherboard, expansion cards, and cooling solutions step by step to ensure a stable and efficient assembly.

  3. Connect cables and power delivery -

    Master the correct routing and attachment of power, data, and fan cables to optimize airflow and system performance.

  4. Implement effective cooling solutions -

    Evaluate and choose between air and liquid cooling options, then apply best practices for installing heatsinks, fans, and thermal paste.

  5. Troubleshoot common assembly issues -

    Analyze and resolve typical errors such as boot failures, hardware conflicts, and cable misconfigurations to refine your PC build test proficiency.

Study Guide

Cheat Sheet

  1. Motherboard Layout & Compatibility -

    Review common form factors (ATX, micro-ATX) and socket types (LGA1200 vs AM4) to ace your computer build test. A handy mnemonic is "Every Socket Means CPU Connect" to remember pairing CPU and board correctly (source: Intel & AMD tech docs).

  2. CPU Installation & Thermal Management -

    Practice applying ~0.5 g of thermal paste in a pea-sized dot and mounting your cooler evenly to avoid hotspots (source: CPU manufacturer guidelines). Use the "3-2-1" rule - 3 turns per screw, 2 screws per side, 1 level mount - to secure the heatsink without warping.

  3. Memory Channel Balancing -

    Install RAM in paired slots (A1/B1 or A2/B2) for true dual-channel performance, boosting bandwidth by up to 20% (source: Kingston Tech Guide). Remember "Pair to Share Faster" to slot sticks correctly before you test your PC build.

  4. Power Supply Sizing & Efficiency -

    Calculate total wattage: CPU + GPU + drives + 20% headroom (e.g., 450 W + 200 W + 50 W = 700 W → choose 850 W PSU). Aim for at least an 80 Plus Bronze rating for >82% efficiency under load (source: PSU manufacturers' calculators).

  5. Cable Management & Airflow Optimization -

    Route cables behind the tray and tie them off to maintain positive air pressure and cool your components (source: PC Building Guide by Tom's Hardware). Use the rhyme "Air Flows Fair When Cables Are Bare" to remember keeping the main chamber clutter-free.
