What is the function of a 2-pin connector located at the bottom right of the motherboard?

The function of a 2-pin connector located at the bottom right of the motherboard is typically to light up the motherboard. This connector is often used for internal LEDs that indicate the power state of the motherboard or other functionalities, such as diagnostic purposes or the status of certain components.

When this connector is engaged with an LED, it allows users to easily see whether the board is receiving power or if there are issues during the boot process. Having visual indicators like this can be crucial in troubleshooting hardware problems since it provides an immediate visual cue about the motherboard's health and operational status.

The other options represent common motherboard connections but do not align with the specific function of a 2-pin connector positioned in that area. For example, fan connections typically use more pins to accommodate speed control features, USB devices connect via headers that support multiple data pins for communication, and CPU power typically requires larger connectors to deliver the necessary voltage and current to the processor.
