A technician is installing several internal components and cabling during a desktop workstation deployment. Match each motherboard power connector or header on the left with its primary operational purpose and device targeted on the right.
- 8-pin EPS12V connectorDelivers dedicated +12V power directly to high-draw central processing units (CPUs).
- 6+2 pin PCIe connectorSupplies supplemental power from the power supply unit (PSU) directly to high-performance expansion cards such as GPUs.
- 20+4 pin ATX connectorProvides primary power (+3.3V, +5V, +12V, and standby voltage) to the motherboard logic board and onboard circuitry.
- USB 3.2 Gen 2 Type-E headerConnects internal motherboard data channels directly to front-panel chassis USB Type-C ports.
Cevap
The 8-pin EPS12V connector matches dedicated CPU power supply; the 6+2 pin PCIe connector matches supplemental graphics expansion card power; the 20+4 pin ATX connector matches primary motherboard system power; and the USB 3.2 Gen 2 Type-E header matches front-panel USB Type-C chassis port connectivity.
Each motherboard header and power connector serves a distinct electrical or signal transfer role: EPS12V delivers isolated +12V current directly to the CPU; 6+2 pin PCIe cables deliver extra power to expansion cards such as GPUs; the 20+4 pin ATX cable delivers main board operational power; and the USB 3.2 Gen 2 Type-E header interfaces the board's USB controller with front-panel USB Type-C ports.
