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 being overloaded.
A computers 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 describe a valid type of PSU?
1.) Make sure the surge protector is turned on 2.) Make sure the power cord is plugged into the wall
An employee submitted a support ticket stating that her computer will not turn on. Which of the following troubleshooting steps should you take first?
1.) The wattage requirement for each individual circuit uses formula W=VxA 2.) The watt rating indicates how much power can be supplied to various devices.
Which of the following statements are true regarding power supply wattage?
Use an adapter cable to connect two 4-pin Molex connectors to the 8-pin PCIe connector.
You are building a new computer from both new and used parts. The video card is PCIe video card that requires an 8-pin power connector. However, your power supply doesn't have an 8-pin PCIe power connector. Which solution would be the least expensive option for your system?
Replace the power supply because it is failing
You are servicing a client's computer that has been randomly restarting. You decide to test the power supply using a multimeter. You connect the positive lead to the yellow wire on one of the Molex connectors. Which action should you take based on the multimeter reading. (10.24 Volts)?
Replace the power supply
