    Study Notes

    Motherboard Connectors

    • Power Connectors:
      • 24-pin ATX power: Standard power connector for motherboards, providing 3.3V ±5V and ±12V power.
      • 20-pin connector compatibility: Older 20-pin connectors can be used with a 24-pin connector.
      • Modular design: Some power supplies offer modular 24-pin connectors with additional pins.
      • Keyed connectors: Pins are keyed to ensure proper insertion orientation.
      • Locking mechanism: A locking mechanism prevents accidental disconnection.
      • Orientation matters: Correct orientation is crucial before connecting.

    CPU Power

    • 4-pin ATX 12V connector: Provides 12V power to the CPU.
    • Location: Usually near the CPU.
    • Labeling: Often labeled as "CPU", "P4", or "ATX 12V".
    • Keyed connector: Ensures proper insertion orientation.

    Storage Connections

    • SATA (Serial ATA) Connectors: Connectors for hard drives and solid-state drives (SSDs).
    • Different layouts and colors: Some motherboards use different colors or layouts.
    • eSATA (external Serial ATA): Allows connection of external storage devices.
    • Expansion cards: eSATA connectors can be added via an expansion card.

    Pin Headers

    • Purpose: Provide connections for various components, such as power, USB, and case button control.
    • Examples:
      • AAFP: External audio connectors.
      • TPM: Trusted Platform Module connector.
      • USB connectors: Legacy and USB 3.0 connectors.
      • Cooling fan controls: Power and control for cooling fans.
    • Positioning: Located at the edge of the motherboard.

    Case Connectors

    • Connection method: Case buttons (power/reset), and lights (power/hard drive) connect to motherboard pin headers.
    • Labeling for clarity: Connectors frequently labeled for correct use.

    M.2 Connector

    • Modern Motherboards: Newer motherboards support M.2 connector for SSD connectivity.
    • Small form factor: Allows for smaller, high-performance storage.
