What type of connector does a modern motherboard with a 24-pin power supply require?

A modern motherboard with a 24-pin power supply requires a 24-pin connector to receive power from the power supply unit (PSU). This connector provides the necessary voltage and current to power the motherboard and connected components. The 24-pin ATX power connector is specifically designed to meet the power requirements of modern processors and other onboard components, ensuring adequate power delivery and stability under load.

The 24-pin connector includes various pins that provide different voltages such as +3.3V, +5V, +12V, as well as ground connections, which are essential for proper operation. A motherboard designed for a 24-pin connector will typically have this specific configuration and will not function correctly with connectors that have fewer pins, such as the 20-pin connector from older systems, which is why the other choices would not be suitable for a modern setup.
