Zorluk: KolayExpansion Cards and Power Supplies

A technician needs to connect supplementary power directly from a power supply unit (PSU) to a newly installed high-performance PCI Express graphics expansion card. Which of the following power connectors is specifically designed for this purpose?

  1. 8-pin (6+2 pin) PCIe connectorCevap
  2. B
    8-pin (4+4 pin) EPS12V connector
  3. C
    15-pin SATA power connector
  4. D
    4-pin Berg connector

Cevap

The 8-pin (6+2 pin) PCIe connector is the correct choice because it is designed specifically to provide dedicated auxiliary power to PCIe expansion cards.
The 8-pin (6+2 pin) PCIe power connector is designed specifically for expansion cards (such as dedicated GPUs) that exceed the standard 75 W power threshold delivered by the motherboard slot.

Adım Adım Çözüm

1
Identify the power requirements of the expansion card
High-performance PCIe expansion cards (such as GPUs) require direct auxiliary power from the power supply unit beyond what the motherboard PCIe slot provides (75 W).
Motherboard expansion slots cannot safely supply sufficient power for high-draw expansion devices alone.
2
Match the requirement to the correct PSU power connector type
Select the 8-pin (6+2 pin) PCIe power connector.
This connector type has the keying and wiring pinout specifically intended for PCIe expansion card power connections.
