IT 286 Week 3 Power Supply Diagnostics & Repair Quiz answer …

Question 1:
– The power supply is responsible for delivering electrical power to the components of a computer system. It converts high voltage AC power from the wall outlet into lower voltage DC power that the components can use.

Question 2:
– The standard voltage output of a power supply is 12 volts DC. This is the voltage used by most computer components, such as the motherboard, processor, and hard drives. Other voltage outputs may include 5 volts and 3.3 volts.

Question 3:
– The main reason for a power supply not turning on is a faulty power switch. This can be due to a loose connection, damaged switch, or a power surge. Checking the power switch and its connections should be the first step in troubleshooting a non-responsive power supply.

Question 4:
– A power supply can fail for a variety of reasons. Some common causes include power surges, overheating, component failure (such as capacitors), or physical damage. It is important to try to identify the cause of the failure in order to prevent future issues.

Question 5:
– A multimeter is a useful tool for diagnosing power supply issues. It can be used to measure the voltage output of the power supply. If the voltage is significantly below the standard voltage output, it may indicate a faulty power supply.

Question 6:
– When replacing a power supply, it is important to choose one with the appropriate wattage. The wattage rating of a power supply indicates how much power it can deliver to the components of a computer system. Choosing a power supply with insufficient wattage can cause instability or system failures.

Question 7:
– When installing a new power supply, it is important to ensure all connections are secure. This includes connecting the power cables to the motherboard, hard drives, and other components, as well as ensuring the power supply is properly grounded.

Question 8:
– In the event of a power supply failure, it is important to first disconnect the power supply from the wall outlet before attempting any repairs or replacements. This reduces the risk of electrical shock or damage to the system.

Question 9:
– In some cases, a power supply may be repairable. This can involve replacing faulty components, such as capacitors, or fixing wiring issues. However, it is often more cost-effective and efficient to simply replace the entire power supply.

Question 10:
– In conclusion, the power supply is a critical component of a computer system. It is responsible for providing the necessary electrical power to all components. When troubleshooting power supply issues, it is important to consider factors such as the voltage output, connections, and possible causes of failure. If a power supply is found to be faulty, it should be replaced with one of appropriate wattage and installed securely. Repairing a power supply is possible in some cases but may not always be the most practical solution.
