Zorluk: OrtaExpansion Cards and Power Supplies

A desktop support technician is installing a new high-performance PCIe x16 graphics card and a PCIe sound card into a workstation. During the upgrade, the technician must configure the power supply connections and verify system power requirements. Which TWO of the following steps or guidelines must the technician follow to ensure safe and reliable operation? (Select TWO)

  1. Connect dedicated 6+2 pin PCIe power connectors from the power supply directly to the graphics card rather than using 8-pin EPS12V CPU power cables.Cevap
  2. B
    Calculate required power supply capacity by adding only the CPU thermal design power (TDP) and GPU thermal design power (TDP) without additional headroom.
  3. Ensure the power supply provides sufficient total continuous wattage that covers total component consumption plus an additional power overhead margin for peak loads.Cevap
  4. D
    Plug the graphics card auxiliary power input into an available motherboard 4-pin chassis fan header using an adapter cable to provide auxiliary +12V power.

Cevap

The technician must connect dedicated 6+2 pin PCIe auxiliary power cables directly to the graphics card (avoiding EPS12V CPU cables) and select a power supply with sufficient continuous wattage to cover total system draw plus a safety overhead margin.
Connecting dedicated PCIe 6+2 pin auxiliary power cables directly to the GPU ensures the correct pinout and amperage delivery. Additionally, provisioning a power supply with continuous capacity that accounts for all system hardware plus an overhead safety margin ensures stability during peak load conditions.

Adım Adım Çözüm

1
Identify the correct auxiliary power cable type for expansion cards.
PCIe 6+2 pin connectors supply +12V power with the proper pinout matching graphics card power inputs.
Connecting EPS12V CPU power connectors to a graphics card can cause severe electrical damage due to incompatible pinouts and reversed polarities.
2
Calculate total system wattage requirements with an appropriate safety margin.
Sum the power consumption of all system components (CPU, GPU, RAM, storage, expansion cards) and add a 20% to 30% headroom margin.
Power supplies operate most efficiently and reliably when peak system power draw does not exceed 70% to 80% of the unit's rated capacity.

Anahtar Kavram

Power supply cable pinout identification and system wattage budgeting with overhead margins.
