A desktop technician is connecting chassis components and power cables to internal system board locations. Match each motherboard connector or header on the left with its primary function or component connection on the right.
- 24-pin ATX Main Power ConnectorSupplies primary DC voltages (+3.3V, +5V, and +12V) directly from the PSU to system board components.
- HD Audio Front Panel HeaderConnects internal audio circuitry to case-mounted 3.5mm headphone and microphone jacks.
- 19-pin USB 3.2 Gen 1 HeaderProvides 5 Gbps data signaling pathways and power for front-facing USB Type-A enclosure ports.
- Chassis Intrusion HeaderConnects motherboard logic to case enclosure micro-switches to record unauthorized access in firmware.
Cevap
The 24-pin ATX main power connector pairs with supplying primary DC voltages from the PSU. The HD Audio header pairs with connecting front 3.5mm audio jacks. The 19-pin USB 3.2 Gen 1 header pairs with providing 5 Gbps data lines to front panel USB ports. The chassis intrusion header pairs with connecting enclosure micro-switches for security logging.
Each motherboard cable connection and internal header serves a dedicated purpose: the 24-pin ATX connector supplies primary multi-rail power, the HD Audio header routes front panel audio jacks, the 19-pin header handles SuperSpeed front USB connectivity, and the chassis intrusion pin header operates security monitoring switches.
