Description: A modular power supply is an essential component in a computer’s architecture that allows users to connect only the cables they need to power their devices. Unlike traditional power supplies, which come with all fixed cables, modular power supplies offer greater flexibility and organization inside the computer case. This not only facilitates installation but also improves airflow and the aesthetics of the system, as unnecessary cables that can cause clutter can be avoided. Modular power supplies are typically classified into three types: fully modular, semi-modular, and non-modular. Fully modular ones allow all cables to be disconnected, while semi-modular ones have some fixed cables, such as the motherboard cable. This type of power supply is especially valued by hardware enthusiasts and gamers, as it allows for more precise customization and more efficient space management. Additionally, many of these units are designed to offer high energy efficiency, meeting standards like 80 PLUS, which translates to lower energy consumption and less heat generation, thus contributing to the longevity of the system.
History: Modular power supplies began to gain popularity in the mid-2000s when hardware enthusiasts started looking for more efficient and organized solutions for cable management in their systems. The first notable model was launched by Corsair in 2007, which introduced the concept of modularity in power supply design. Since then, many other brands have followed suit, improving technology and offering products with varying levels of modularity and energy efficiency.
Uses: Modular power supplies are primarily used in custom computer builds, especially in high-performance systems such as workstations and gaming PCs. Their modular design allows users to tailor the cable configuration to their specific needs, resulting in a cleaner and more efficient installation. They are also ideal for users who frequently upgrade their hardware, as they facilitate access to internal components.
Examples: An example of a modular power supply is the Corsair RM850x, which offers 80 PLUS Gold efficiency and a fully modular design, allowing users to connect only the necessary cables. Another example is the EVGA SuperNOVA 750 G5, which is also fully modular and provides reliable performance for high-performance systems.
