Difficulty: EasyExpansion Cards and Power Supplies

A technician is installing a dedicated high-performance graphics card into a desktop computer. Which of the following components and power connections are required to properly install and supply supplementary power to this expansion card? (Select TWO.)

  1. A dedicated PCIe 6-pin or 8-pin auxiliary power cable from the power supply unitAnswer
  2. A physical PCIe x16 motherboard expansion slotAnswer
  3. C
    An EPS12V 8-pin CPU power connector plugged directly into the graphics card
  4. D
    A 4-pin Molex adapter connected directly to the motherboard 24-pin main power socket

Answer

A dedicated PCIe 6-pin or 8-pin auxiliary power cable from the power supply unit and a physical PCIe x16 motherboard expansion slot are required.
Installing a high-performance graphics card requires inserting the card into a physical PCIe x16 slot for maximum bus bandwidth and connecting dedicated 6-pin or 8-pin PCIe power cables from the power supply to meet the card's wattage requirements above the 75 W provided by the slot.

Step-by-Step Solution

1
Identify the required expansion slot type for a high-performance graphics card.
The card requires a PCIe x16 motherboard slot.
PCIe x16 provides the physical dimensions and maximum bus bandwidth needed for video processing.
2
Determine the supplementary power requirement beyond standard slot power.
Connect a 6-pin or 8-pin PCIe auxiliary power cable directly from the power supply to the graphics card.
The PCIe motherboard slot provides up to 75 W of power; power draw exceeding 75 W must be supplied via dedicated PCIe auxiliary cables.
