Which computer component provides power to the system?

• A. Wireless Network Card
• B. CPU
• C. Motherboard
• D. Power Supply

Answer: (D)

Power supply is the component that provides power to the system by converting mains AC into the DC voltages that all parts rely on. It delivers rails such as +12V, +5V, and +3.3V through connectors to the motherboard, drives, and graphics card. The CPU and other devices draw power from these rails via the motherboard’s voltage regulation. The wireless network card also consumes power from the system, but it does not generate power. The motherboard serves as the platform that distributes power and data, while the actual power comes from the power supply. Without it, the computer cannot boot or run.
