Which of the following power supplies would provide the BEST solution?

  • A. 1000W 24-pin modular power supply
  • B. 220VAC 9000J surge protector
  • C. 500W redundant power supply
  • D. 2000VA uninterruptible power supply

Selected Answer: A
High Power Capacity: Dual graphics cards and high-performance workstations require significant power. A 1000W power supply provides ample power to support these components reliably. Modular Design: A modular power supply allows for better cable management and improved airflow within the case. It enables the installation of only the necessary cables, reducing clutter and enhancing cooling efficiency. 24-pin Connector: This is a standard connector for modern motherboards, ensuring compatibility with a wide range of systems.

Based on what I encounter in these CompTIA questions, you always need to pick up clues from the questions and read between the lines. In this case, they specifically mentioned dual video cards may or may not be added. There's no mention of redundancy. So a modular 1000W PSU meets the requirements. If the team eventually decides to go through with the plan to add a second GPU, you can easily add them with enough power to spare.

C. 500W redundant power supply A redundant power supply is designed to provide backup power in case one power supply unit fails. In a scenario where the management team has not decided on installing dual graphics cards, a 500W redundant power supply would be a good solution. It provides redundancy to ensure continuous power supply in case one unit fails, and it has sufficient wattage (500W) to handle the power requirements of workstations, including the possibility of dual graphics cards in the future. Options A and B are not specifically redundant power supplies. Option D, the 2000VA uninterruptible power supply (UPS), is designed to provide backup power in case of outages but doesn't inherently provide redundancy like a redundant power supply would.

Remember its dual GPU and a single GPU takes up the majority of the power supply wattage

A 1000W 24-pin modular power supply provides enough power to support a dual graphics card configuration, which requires a significant amount of power. A modular power supply allows the technician to connect only the cables that are necessary for the current configuration, reducing cable clutter and improving airflow inside the case. This makes it easier to install and maintain the power supply.

why not C ? Redundant seems to be the most fit answer here.

To ensure a reliable power supply solution and taking into consideration potential future upgrades such as dual graphics cards the best option would be a 2000VA uninterruptible power supply (UPS).

While a UPS (Uninterruptible Power Supply) can provide backup power during brief power outages, it's not designed to be a permanent power source for a workstation. Its primary function is to provide a smooth transition to battery power in case of a power outage, allowing the user to save their work and shut down the system gracefully. In the context of the prompt, the workstations need a reliable and continuous power supply, especially considering the potential for high power consumption from dual graphics cards. A UPS, while useful for protecting against short-term power interruptions, cannot provide the long-term, high-power solution required for these workstations. Therefore, while a UPS can be a valuable addition to a workstation setup, it's not the primary solution for addressing the power supply needs of workstations with dual graphics cards. GG

1000W 24-pin modular power supply refers to a power supply unit (PSU) for a desktop computer. So its basicly for a single workstation.
