Zorluk: OrtaExpansion Cards and Power Supplies

A technician is configuring hardware components and power connections for a workstation build. Match each expansion interface or power supply connector on the left with its correct technical specification or power delivery function on the right.

  • PCIe 6+2 pin connectorSupplies auxiliary +12V power (up to 150 W) directly to high-draw expansion cards such as GPUs.
  • EPS12V 8-pin connectorDelivers dedicated power exclusively to the motherboard processor socket.
  • PCIe x16 slotProvides up to 75 W of direct bus power to an installed expansion card via the motherboard.
  • Molex 4-pin connectorProvides legacy +5V and +12V DC power for peripheral drives and case fans.

Cevap

PCIe 6+2 pin connector matches auxiliary GPU power (up to 150 W); EPS12V 8-pin connector matches dedicated motherboard CPU power; PCIe x16 slot matches direct motherboard bus power (up to 75 W); Molex 4-pin connector matches peripheral drive and fan power (+5V and +12V).
Each connector and interface serves a distinct power role in PC architecture: PCIe 6+2 connectors supply auxiliary power up to 150 W to demanding expansion cards, EPS12V supplies CPU power, the PCIe slot itself provides up to 75 W through motherboard traces, and 4-pin Molex supplies dual-voltage power to legacy peripherals.

Adım Adım Çözüm

1
Identify PCIe expansion auxiliary power requirements
Recognize that PCIe 6+2 pin connectors supply auxiliary power to high-power cards (up to 150 W for an 8-pin connection).
High-end GPUs require more wattage than the slot alone can deliver.
2
Distinguish processor power from PCIe auxiliary power
Map EPS12V 8-pin connector to dedicated processor power.
EPS12V supplies high-current +12V power directly to the CPU voltage regulator module on the motherboard.
3
Determine slot-supplied motherboard power capacity
Map the PCIe x16 slot to 75 W motherboard bus power.
PCI Express specifications dictate that standard motherboard slots provide a maximum of 75 W directly to the card without needing external cables.
4
Identify legacy peripheral connector standards
Map the Molex 4-pin connector to peripheral drive and fan power delivering +5V and +12V.
Molex connectors feature pinouts for both 5-volt and 12-volt direct current applications.
