    Study Notes

    Motherboard Connectors

    • 24-Pin Power Connector: Provides main motherboard power (3.3V ±5V, ±12V). Replaced the 20-pin connector. Some power supplies have a modular 24-pin connector with 20-pin base and 4 additional pins. Individual pins are keyed for correct orientation. Includes a locking mechanism.

    CPU Power Connector (4-Pin ATX)

    • Delivers 12V power specifically for the CPU. Located near the CPU. Identifiable with "CPU", "P4", or "ATX 12V" labeling. Also keyed for proper insertion.

    SATA Connectors

    • Used for connecting hard drives and SSDs. Colored connectors. Different layouts and colors are possible but all serve the same function.
    • eSATA: External Serial ATA connection, either through a built-in interface or expansion card. Allows for external storage devices with similar speed/performance to internal storage devices.

    Pin Headers

    • Groups of pins at the edge of the motherboard. Connect to various components: power, USB, case buttons.
    • Identified by labels (e.g., AAFP for external audio connectors). Varying types and functions across different locations

    TPM, USB, and Fan Connectors

    • Motherboard may contain:
      • TPM (Trusted Platform Module) connector
      • Legacy USB connectors
      • USB 3.0 connectors
      • Connectors for controlling cooling fans

    Case Connectors

    • Control buttons (power, reset): Connected to designated motherboard pins via connectors on the case. Connectors marked for precise placement.
    • Hard drive activity and power lights: Connected to related pins on the motherboard.

    M.2 Connector

    • Newer motherboards feature M.2 connectors. Commonly used for SSDs for fast storage.
    • Direct plug-in to the M.2 connector on the motherboard. Requires fastening the drive to the motherboard for secure connection.
