Motherboard Connectors — CompTIA A+ Core 1 (220-1101) Practice Questions

Motherboard connectors are the physical interfaces that link the motherboard to power, storage, displays, and peripheral devices, and understanding them is fundamental to the CompTIA A+ Core 1 exam. Key connector types include the 24-pin ATX main power connector, 4/8-pin CPU power connector, SATA data ports, M.2 slots, PCIe expansion slots, front-panel headers, and USB headers. Technicians must be able to identify each connector visually, understand its purpose, and correctly seat cables during installation or repair. Misidentifying or improperly connecting these interfaces is a common source of hardware failure in the field.
