Exam 220-1101 topic 1 question 449 discussion

C is the wrong answer A is the correct answer An 8-pin PCIe (Peripheral Component Interconnect Express) power cable is required to provide adequate power to each GPU in an SLI (Scalable Link Interface) configuration. High-performance GPUs often require more power than the PCIe slot on the motherboard can supply, necessitating additional power directly from the power supply. The 8-pin PCIe connector can deliver more power than the standard 6-pin connector, making it suitable for high-end graphics cards commonly used in SLI configurations. This requirement is consistent with the hardware installation and configuration principles covered in the CompTIA A+ Core 1 (220-1101) Exam Objectives, particularly in sections dealing with hardware components and their installation .

I think PCIe 8 pin was good for gpu but now they require more power. maybe the next A+ will have 8+6 or 12 pin

while GPUs can be powered through PCIe, higher powered components can be powered by pin connectors. really depends on the component, but since it's SLI, going with pins

4+4 pin connectors are NOT for GPUs, they are for CPUs GPUs utilize 8 pin PCIe

Reasoning: 1.SLI Configuration: Since the workstation is running multiple GPUs in an SLI configuration, it requires a power supply that can provide sufficient power to each GPU. 2.Power Requirements: Each GPU typically requires a 6-pin or 8-pin PCIe power connector. To support multiple GPUs, the power supply needs to have multiple 6-pin or 8-pin PCIe power connectors, which are usually provided through a 4+4-pin ATX12V connector. 3.Power Supply Requirements: The 4+4-pin ATX12V connector is a common connector found on power supplies that can provide up to 300W of power to the CPU and other components. This connector is necessary to ensure the power supply can support the workstation's power requirements.

When upgrading the power supply of a workstation running multiple GPUs in an SLI configuration, the technician will likely need cables that can provide sufficient power to the graphics cards. In this scenario, the appropriate cable needed is: A. 8-pin PCIe.
