Which of the following connectors provide power to the system board? (Select TWO).

The correct answer is D. 4-pin 12v E. 24-pin ATX. The 24-pin ATX connector is the main motherboard power connector that supplies multiple voltage rails (+3.3V, +5V, +12V) for the board's general operation. The 4-pin (or 8-pin) 12V ATX12V connector specifically powers the CPU voltage regulator. Together, these two connectors…

Explanation

The 24-pin ATX connector is the main motherboard power connector that supplies multiple voltage rails (+3.3V, +5V, +12V) for the board's general operation. The 4-pin (or 8-pin) 12V ATX12V connector specifically powers the CPU voltage regulator. Together, these two connectors provide all the power the motherboard requires. IDE and SATA connectors are data (and SATA power) interfaces for storage devices. Molex is a legacy 4-pin power connector for older drives and fans. The 6-pin PCIe connector powers discrete graphics cards - not the motherboard itself.
