Which type of power supply could be used with a motherboard that requires a 24-pin connector?

A power supply that has a 20-pin connector along with a 4-pin connector can indeed be used with a motherboard that requires a 24-pin connector. This is because many modern motherboards are designed with flexibility in mind. The 20-pin connector provides the necessary power and the additional 4-pin connector is commonly used to provide extra power, particularly for high-performance CPUs or when additional components demand it. When the two connectors are combined, they can effectively create the required 24-pin connection. Therefore, it suffices to power the motherboard properly without causing any issues.

In contrast, a power supply that has only a 24-pin connector would also be suitable, but the inclusion of a 20-pin and an additional 4-pin provides compatibility for older systems as well. The other options, such as power supplies with 8-pin or 16-pin connectors, would not supply the necessary connections or power configuration required by a motherboard requiring a 24-pin connector, making them incompatible with that specific requirement.
