CompTIA A+ Core 1 (220-1101) — Question 134

A user reports that a computer will not turn on. The technician verifies the power cord and the outlet the computer are plugged into are both working properly. Which of the following is the hardware component that has MOST likely failed?

Answer options

• A. PSU
• B. CPU
• C. RAM
• D. GPU

Correct answer: A

Explanation

The Power Supply Unit (PSU) is responsible for supplying power to the computer components. If the computer does not turn on despite a working power cord and outlet, the PSU is the most probable failure point. The CPU, RAM, and GPU would not prevent the system from powering on if the PSU is functional.
