A desktop support technician is tasked with replacing the power cables for a series of desktop computers that have recently been updated to a newer model. The technician notices that the new desktops have a different power supply unit (PSU) design. Which type of power cable should the technician ensure is used for the newer desktop models?
Correct Answer: B
Correct Answer. B. Standard three-prong power cable Most modern desktop computers require a standard three-prong power cable, also known as a C13/C14 coupler. This cable is suitable for connecting the desktop to an AC power source, providing a grounded and safe power connection necessary for the higher power requirements of newer desktop models. Option A is incorrect because two-prong power cables typically do not provide grounding, which is essential for the safety and proper operation of desktop computers. Option C is incorrect because USB power cables are not capable of delivering the required voltage and current for desktop computers. Option D is incorrect because desktop computers do not use proprietary adapters similar to those used for laptops; they generally use standardized cables.
