Free CompTIA A+ 220-1101 Practice Question

A technician is upgrading a motherboard in an older desktop machine which requires a 24-pin power connector. However, the existing power supply only has a 20-pin power connector. What is a potential consequence of using a 20-pin to 24-pin adapter for this upgrade?

  • The adapter includes additional capacitors that smooth out the power supply's output, thus stabilizing the system.

  • The adapter increases power efficiency by reducing the number of active power lanes to the motherboard, which will save energy.

  • Using the adapter will double the data transfer rate between the power supply and the motherboard.

  • It may lead to insufficient power distribution to the motherboard, causing instability or underperformance.
