When selecting a power supply, which specification is critical to match with the motherboard to ensure proper connectivity?

• A. Voltage rating
• B. Connector type
• C. Efficiency rating
• D. Brand compatibility

Answer: (B)

When selecting a power supply for a motherboard, the connector type is critical for ensuring proper connectivity. Motherboards typically require specific connectors from the power supply to function correctly. These include the 24-pin ATX power connector, which is essential for supplying power to the motherboard, as well as additional connections like the 4-pin or 8-pin CPU power connector, and potentially others for additional components. If the connector type doesn't match, the power supply will not connect to the motherboard at all, leading to failure in powering up the system. For example, using a power supply with a 20-pin connector on a motherboard that requires a 24-pin connector would be inappropriate. Ensuring the correct connector type is chosen helps maintain compatibility and ensures that all required connections can be made securely. While voltage rating, efficiency rating, and brand compatibility are all important factors in selecting a power supply, they do not directly affect the immediate physical connection between the power supply and the motherboard. Hence, focusing on connector type is paramount for establishing that necessary connection.
