CompTIA A+ Core 1 (220-1101) — Question 162

Which of the following should a user do FIRST when upgrading the power supply on a gaming PC?

Answer options

• A. Update the BIOS
• B. Disconnect the system memory
• C. Check the wattage rating
• D. Reseat the graphics card

Correct answer: C

Explanation

The correct answer is C because verifying the wattage rating of the new power supply ensures it meets the power requirements of the gaming PC. The other options are not the first steps; updating the BIOS or disconnecting memory is unnecessary at this stage, and reseating the graphics card is only relevant after ensuring the power supply is compatible.
