What does the 24-pin power connector do?

  1. Provides power to the CPU only

  2. Supplies power to the motherboard

  3. Allows data transfer to peripherals

  4. Connects the GPU to the motherboard

The correct answer is: Supplies power to the motherboard

The 24-pin power connector, also known as the ATX power connector, is primarily responsible for supplying power to the motherboard itself. This connection provides the necessary electrical power to the various components on the motherboard, including the chipset, memory, and expansion slots. It plays a crucial role in ensuring that the motherboard can operate and support the functioning of all connected devices. While the connector does support power to the CPU via separate power lines from the motherboard, its main function encompasses providing power beyond just the CPU, extending to all essential components on the motherboard. This distinguishes the 24-pin connector from connectors that serve specific purposes, such as data transfer or connections for graphics processing units (GPUs). Thus, its key role is to ensure that the motherboard and its associated hardware receive the power they need for operation.
