11. 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? (Select two).
Answer: C,F
Adding an optical drive and upgrading the graphics card would most likely cause the insufficiency.
Adding an optical drive and upgrading the graphics card typically require more power from the PSU, which can lead to insufficiency in power supply, especially if the existing PSU is not rated to handle the additional load.
A) Replacing the HDD with an SSD
Replacing an HDD with an SSD generally does not require additional power, as SSDs consume less power than traditional hard drives. Therefore, this option is unlikely to contribute to a power insufficiency.
B) Upgrading the firmware
Upgrading firmware is a software process that does not impact the hardware power requirements of a computer. This action does not draw additional power from the PSU, making it an unlikely cause of power insufficiency.
C) Adding an optical drive
Adding an optical drive increases the total load on the power supply unit, as it introduces a component that consumes additional power. This can lead to an insufficient power supply if the PSU is already near its limits.
D) Adding more RAM
While adding more RAM does increase power consumption, the amount is relatively low compared to other components. Therefore, while it may contribute to power draw, it is not likely to be a primary cause of power insufficiency.
E) Adding a CMOS battery
Adding a CMOS battery is a minimal power requirement that is negligible in the context of overall power consumption. This option does not significantly affect the power supplied by the PSU.
F) Upgrading the graphics card
Upgrading the graphics card typically demands a significant amount of power, as modern GPUs are designed to handle advanced graphics and processing tasks. This can easily exceed the capacity of an underpowered PSU, making it a likely contributor to power insufficiency.
Conclusion
In summary, both adding an optical drive and upgrading the graphics card are actions that increase the power demand of the system, potentially exceeding the PSU's capacity. Other options, such as replacing an HDD with an SSD, upgrading firmware, adding RAM, or adding a CMOS battery, do not significantly contribute to power insufficiency and therefore are not likely causes.
