CompTIA A+ Core 1 (220-1001) — Question 404

Which of the following should be considered FIRST when upgrading the power supply on a high-end gaming PC?

Answer options

• A. Wattage rating
• B. PSU redundancy
• C. Cooling fans
• D. 20+4 pin adapter

Correct answer: A

Explanation

The wattage rating is the most crucial aspect to consider first when upgrading a power supply, as it determines if the PSU can handle the total power requirements of all components. PSU redundancy, cooling fans, and the 20+4 pin adapter are important but secondary considerations that come into play after ensuring the wattage is sufficient.
