Difficulty: EasyMotherboards Form Factors and Connectors

Match each motherboard form factor or connector on the left with its correct specification or primary function on the right.

  • Mini-ITX Form FactorCompact square layout measuring 6.7 x 6.7 inches (17 x 17 cm)
  • 24-pin ATX ConnectorDelivers primary power (+3.3V, +5V, +12V) directly to the mainboard
  • 8-pin EPS12V ConnectorProvides dedicated auxiliary +12V power directly to modern CPUs
  • PCIe x16 SlotOffers high-bandwidth expansion lanes primarily used for discrete GPUs

Answer

Mini-ITX Form Factor matches compact square layout measuring 6.7 x 6.7 inches; 24-pin ATX Connector matches delivers primary power directly to the mainboard; 8-pin EPS12V Connector matches provides dedicated auxiliary +12V power directly to modern CPUs; PCIe x16 Slot matches offers high-bandwidth expansion lanes primarily used for discrete GPUs.
Each motherboard term correctly matches its corresponding technical specification, physical dimension, or power/expansion function based on CompTIA A+ hardware standards.

Step-by-Step Solution

1
Identify the standard dimensions for the Mini-ITX motherboard form factor.
Mini-ITX measures exactly 6.7 x 6.7 inches (17 x 17 cm).
It is designed for small form factor (SFF) computer enclosures.
2
Determine the role of the 24-pin ATX power connector.
It supplies mainboard power across multiple voltage rails (+3.3V, +5V, +12V).
Modern motherboards require a single primary 24-pin connection to power basic board logic and chipset features.
3
Identify the purpose of the 8-pin EPS12V power connector.
It connects near the processor to provide dedicated +12V power to the CPU.
Modern processors require dedicated auxiliary power beyond what the main 24-pin ATX cable can safely deliver.
4
Identify the expansion card capability of a PCIe x16 slot.
It provides 16 full serial lanes of communication bandwidth.
High-performance expansion cards such as discrete GPUs require maximum throughput.
