Zorluk: OrtaMotherboards Form Factors and Connectors

A computer technician is assembling a desktop workstation and connecting cables from the power supply unit (PSU) to the motherboard. After successfully connecting the 24-pin ATX main power connector, the technician needs to provide dedicated auxiliary power to the processor socket. Which of the following power connectors should be plugged into the 8-pin port located adjacent to the CPU socket?

  1. 8-pin EPS12V power connectorCevap
  2. B
    8-pin PCIe power connector
  3. C
    4-pin Molex power connector
  4. D
    15-pin SATA power connector

Cevap

The 8-pin EPS12V power connector is the correct choice for supplying dedicated auxiliary power directly to the CPU socket on the motherboard.
The 8-pin EPS12V power connector (or 4+4 pin CPU power cable) delivers dedicated +12V power directly to the processor via motherboard voltage regulator modules located adjacent to the CPU socket.

Adım Adım Çözüm

1
Identify the power requirements for the central processing unit (CPU).
Modern CPUs consume significant electrical current beyond what the 24-pin ATX motherboard main connector can deliver.
Dedicated +12V power lines are required near the processor socket to feed the CPU Voltage Regulator Module (VRM).
2
Evaluate the matching motherboard header and cable standard.
The 8-pin port located near the CPU socket matches the EPS12V standard (often split as a 4+4 pin connector on modular PSUs).
Connecting an EPS12V cable ensures correct voltage delivery and prevents system instability or POST failure.
