Replacing the power supply with one that has a higher wattage rating will best address the issue. Installing a second power supply or changing the voltage input won’t necessarily provide the additional power needed. Similarly, changing the output to 5V doesn’t necessarily mean the power supply can provide more wattage.

For high-end graphics work, a workstation would benefit from a power supply with a high wattage rating. The 700W power supply would provide the most power for high-performance parts like a graphics card. The other options, while they might function, would not provide the same level of power and could potentially lead to performance issues.

The correct answer is a power supply with an 80 PLUS Gold rating. This type of power supply is specifically designed to be efficient at intermediate (20-100%) load levels. The other options are incorrect because they are either less efficient or designed to be efficient at full load levels.

Ordering a power supply with a 3.3V output is the best solution as it will meet the motherboard’s requirements. Using a 5V or 12V power supply could damage the components as they provide more voltage than required. Using a power supply with a 220–240 VAC input doesn’t address the voltage output requirement.

The energy efficiency rating of a power supply indicates how much of the input power is successfully converted into output power for the system, making it the most relevant specification for improving energy efficiency. Wattage rating, voltage output, and redundancy capability do not directly relate to energy efficiency.

The correct answer is to wait and order a 5V power supply. Installing a 3.3V power supply in a system that requires 5V can lead to insufficient power delivery and potential hardware damage. Using a voltage converter or attempting to modify the power supply are risky options that can also lead to hardware damage.

The 24 pin connector can fit into a 20+4 pin motherboard slot. The additional 4 pins are designed to be detachable to accommodate older motherboards. Hence, there is no need to purchase a new power supply or use an adapter.

The redundant power supply should have the same output voltage as the primary power supply to ensure it can adequately power the server in the event of a primary power supply failure. The wattage rating of the redundant power supply is less critical, as long as it meets the minimum requirements for the server.

The 1000W power supply with an 80+ Platinum efficiency rating would be the best choice. It has enough power to handle the server’s needs and has a high energy efficiency rating, which can help save on energy costs. While the other options may have sufficient wattage, their efficiency ratings are lower, meaning they will use more energy to deliver the same amount of power.

A modular power supply is the best choice because it allows for redundancy in case one module fails. The voltage input and output options (110–120 VAC, 220–240 VAC, and 3.3V output) are irrelevant to the requirement of redundancy or the 20+4 pin connector.

The correct answer is a PSU with a wattage rating of 900W. A higher wattage PSU will not harm the system, and it gives a buffer for power spikes or future upgrades. The other options are incorrect because they offer less wattage than required or just meet the requirement without any room for power spikes or future upgrades.

A power supply tester can be used to check if the power supply is providing the correct output to the system’s components. If it’s not, then the power supply is likely the problem. While checking the input voltage setting and the wattage rating can provide useful information, they would not directly confirm if the power supply is functioning correctly. Replacing the power supply without confirming it’s the problem could lead to unnecessary costs.

The correct answer is to use the 24-pin connector as it is. The extra 4 pins in a 24-pin power connector are designed to be detachable so that the connector can be used with either a 20-pin or a 24-pin motherboard. The other options are not suitable as leaving 4 pins unattached can result in insufficient power delivery, and purchasing a new power supply or an adapter is an unnecessary expenditure.

The correct answer is to wait and order a redundant power supply. For a server running several virtual machines, redundancy in power supply is crucial to prevent downtime. Installing a standard power supply or using two standard power supplies won’t provide the needed redundancy, and modifying a standard power supply to act as a redundant power supply is not feasible.

The correct answer is a redundant power supply. This type of power supply allows for continuous operation even if one module fails, making it ideal for mission-critical servers. The other options are incorrect because they do not provide the redundancy needed for continuous operation in case of module failure.

Using an adapter to convert the 24 pin connector to a 20+4 pin connector is the best solution, as it will allow the power supply to connect to the motherboard without needing to replace the power supply. Using a power supply with a 20 pin or 4 pin connector will not provide all required connections, and using a power supply with a 5V output does not address the connector issue.

The 80 PLUS certification guarantees that the power supply is at least 80% energy efficient at 20%, 50% and 100% of rated load. None of the other options directly affect the energy efficiency of a power supply.

The correct answer is to set the power supply switch to 220-240 VAC. When installing a power supply, it’s important to match the input voltage with the voltage provided by the power outlet to prevent damage to the power supply or the system. The other options are not correct as they can lead to incorrect voltage supply which could damage the power supply or system components.

Checking the power supply’s voltage output with a multimeter will help the technician determine if the power supply is delivering the correct voltage to the system components. If the voltage is lower than what’s required, it can cause the system to power off unexpectedly. The other options are not as direct or may not accurately diagnose the power supply problem.

The correct answer is a modular power supply with a 20+4 pin motherboard connector. This is because the modular power supply allows flexibility in connecting different types of cables, including the required 20+4 pin motherboard connector. The other options are incorrect because they either lack the necessary pin configuration or do not offer the flexibility of a modular power supply.

The 5V rail on a power supply typically provides power to the hard drives, older motherboard logic, and various other electronics on the motherboard.

European countries typically use a mains electricity supply rated at 220-240V, 50Hz. Therefore, the technician should set the power supply to 220-240 VAC. The other settings would either not provide enough power (110-120 VAC) or are not relevant to the voltage setting (modular power supply and wattage rating).

The correct answer is to use an adapter to convert the 8-pin connector to a 6-pin connector. Modular power supplies often come with a variety of adapters for different connector types. Using the 8-pin connector as it is or connecting only 6 pins might potentially damage the motherboard or the power supply, and purchasing a new power supply is an unnecessary expenditure.

The correct answer is 220-240 VAC. This is because the company’s server room has a dedicated power line that supplies 220-240 VAC. Therefore, the power supply unit should be compatible with that voltage. Options 110-120 VAC, 3.3V, and 5V are incorrect as they do not match the voltage supplied by the dedicated power line.

The main purpose of a redundant power supply is to maintain server uptime even if one power supply fails. The other options, while potentially beneficial, are not the primary reasons to use a redundant power supply.
