What type of connectors are used for power on a motherboard?

The correct type of connectors used for power on a motherboard are 24-pin or 20+4 pin connectors. These connectors are vital in delivering power from the power supply unit (PSU) to the motherboard.

The 24-pin (or 20+4 pin) connector is designed to provide a stable and robust power source to the motherboard, supporting modern CPUs and various components. The additional 4 pins in the 20+4 configuration can be used or left detached depending on the motherboard's requirements; they ensure compatibility with both older and newer motherboards. This adaptability is essential since many power supplies still include the option for a 20-pin connector to accommodate legacy systems, while the extra 4 pins cater to systems needing additional power.

In contrast, connectors like the 8-pin or 12-pin types are used for specific functions, such as providing power to the CPU directly but are not the primary connectors for overall motherboard power. The 20-pin connector was also common in older motherboards but has largely been replaced by the more standardized 24-pin connector in contemporary designs.
