Zorluk: KolayMotherboards Form Factors and Connectors

A technician is installing components on a standard motherboard during a system build. Match each motherboard component or connector on the left with its correct function or physical specification on the right.

  • 24-pin ATX connectorSupplies main system power to the motherboard chipset and onboard buses
  • 4/8-pin EPS12V connectorDelivers dedicated 12V power directly to the central processing unit (CPU)
  • PCIe x16 expansion slotProvides high-speed data throughput typically used for dedicated graphics cards
  • Front panel header pinsConnects chassis power buttons, reset switches, and activity LEDs to motherboard control logic

Cevap

The 24-pin ATX connector pairs with main motherboard power; the 4/8-pin EPS12V connector pairs with dedicated CPU power; the PCIe x16 slot pairs with high-speed bandwidth for graphics cards; and the front panel header pins pair with computer case switches and status LEDs.
Each motherboard component serves a specific interface requirement: the 24-pin ATX connector supplies general system power, the 4/8-pin EPS12V connector supplies dedicated power to the CPU, PCIe x16 provides high bandwidth for graphics expansion, and front panel headers connect chassis switches and status lights.

Adım Adım Çözüm

1
Identify the primary electrical function of the main motherboard power input.
The 24-pin ATX connector supplies main power across motherboard chipsets and onboard components.
Modern motherboards draw baseline system power via the 24-pin ATX harness.
2
Identify the secondary dedicated processor power connection.
The 4/8-pin EPS12V connector delivers dedicated 12V power to the processor.
Modern CPUs require focused power regulation separate from general motherboard components.
3
Determine the highest-bandwidth expansion slot standard used on desktop motherboards.
PCIe x16 expansion slot matches high-speed data interconnect for graphics cards.
PCIe x16 provides 16 full-duplex lanes required by dedicated GPUs.
4
Determine the purpose of small pin headers located near the motherboard edge.
Front panel header pins match computer case buttons, switches, and LEDs.
Front panel pin arrays route low-voltage signals from chassis switches to internal motherboard logic.
