A technician made several upgrades to a computer and then determined the power supplied by the PSU is insufficient. Which of the following would MOST likely cause the insufficiency? (Choose two.)

The correct answer is C. Adding an optical drive F. Upgrading the graphics card. Optical drives (C) require dedicated power connectors and add meaningful wattage draw to the system. Discrete graphics cards (F) are by far the largest power consumers in a PC, with high-end GPUs potentially requiring 200–400W on their own - upgrading one is the most common reaso

Explanation

Optical drives (C) require dedicated power connectors and add meaningful wattage draw to the system. Discrete graphics cards (F) are by far the largest power consumers in a PC, with high-end GPUs potentially requiring 200–400W on their own - upgrading one is the most common reason a PSU becomes insufficient. Replacing an HDD with an SSD (A) actually reduces power consumption. Upgrading firmware (B) is a software action with no hardware power impact. Adding RAM (D) adds only a few watts and rarely strains a PSU. A CMOS battery (E) is a small 3V coin cell that draws negligible power.
