What is a feature of a modular power supply unit?

A modular power supply unit is designed to enhance flexibility and organization within a computer system. This type of power supply allows users to attach only the cables that are necessary for their specific components, which helps to reduce cable clutter and improve airflow within the case.

The correct answer regarding the feature of a modular power supply unit indicates that it supports multiple devices with a single connector. This is typically seen in the context of modular cables that can be connected to various components, such as the motherboard, graphics cards, and drives, without the need for a permanently attached cable for each device.

In a modular setup, users can select which components need power based on their system's configuration, providing a streamlined installation process and making it easier to manage cables. This adaptability is a significant advantage over non-modular power supplies, which come with all cables permanently attached, making for a more complicated and cluttered setup.

In contrast, options relating to attaching multiple cables directly to the motherboard or adjusting wattage automatically describe different functionalities not specifically tied to modular designs. Providing power only to essential components is more about optimization in power supply design, rather than the modular feature itself.
