A computer's power supply converts mains AC to low-voltage regulated DC power for the internal components of a computer. You are building a new computer. You are deciding which type of power supply to install. Which of the following definitions BEST describes a valid type of power supply? Correct Answer: A single-rail power supply provides one rail (PCB trace). This provides the best safety for the computer by providing a single point of shutdown in the event of a short circuit. Correct Answer: A single-rail power supply provides one rail (PCB trace) used to always provide equal wattage to all devices attached to the power supply. Correct Answer: A dual-rail power supply provides separate rails (PCB traces) used to provide equal wattage to the devices attached to each rail. Correct Answer: A dual-rail power supply provides separate rails (PCB traces) used to balance the power load between multiple circuits, which prevents any one circuit from becoming overloaded.
