Match each motherboard connector or form factor specification on the left with its primary function or structural requirement on the right.
- 8-pin EPS12V power connectorSupplies dedicated +12V DC power directly to the processor's voltage regulator module (VRM).
- 24-pin ATX main power connectorDelivers multi-voltage lines (+3.3V, +5V, +12V, -12V) and +5VSB standby power to system logic.
- Front panel system header (F_PANEL)Interfaces chassis-mounted momentary switches, power/drive activity LEDs, and system diagnostic pinouts.
- Mini-ITX form factor standardSpecifies maximum dimensions of 6.7 × 6.7 inches (17 × 17 cm) and typically supports a single expansion slot.
Answer
The 8-pin EPS12V power connector matches with supplying dedicated +12V DC power to the processor VRM; the 24-pin ATX main power connector matches with delivering multi-voltage lines (+3.3V, +5V, +12V, -12V) and standby power to system logic; the front panel system header matches with interfacing chassis momentary switches and activity LEDs; and the Mini-ITX form factor standard matches with specifying 6.7 × 6.7 inch dimensions and supporting a single expansion slot.
Each motherboard element matches its precise technical standard: EPS12V delivers dedicated CPU power to the VRM, 24-pin ATX delivers primary system power rails, the front panel header routes low-voltage chassis switch/LED signals, and Mini-ITX defines a compact 6.7 x 6.7 inch layout with one PCIe slot limit.
