Learn about the different levels of PSU modularity and their importance in gaming PCs. Whether you’re considering non-modular, semi-modular, or fully modular power supplies, discover how they impact future upgrades and cable management. Read our guide to gain insights into choosing the right PSU modularity for your gaming needs.
Power supplies for gaming PCs can be categorized as non-modular, semi-modular, or fully modular. While power supply modularity may not be the primary concern during PC assembly, it becomes significant when considering future upgrades and cable management. In this article, we will elucidate and explore the distinctions between these PSU modularities.
Non-modular power supplies represent the most basic type available in the market. They come with all necessary cables permanently attached to the unit, leaving no option to remove unwanted cables. Furthermore, non-modular power supplies generally offer fewer features compared to their modular counterparts. However, they are often more affordable, making them a suitable choice for budget-conscious buyers.
Semi-modular power supplies provide a middle ground between non-modular and fully modular units. They come with some cables pre-attached, while also including a selection of modular cables that can be used as needed. This grants a degree of flexibility during installation and enables customization of cable management to some extent.
Semi-modular power supplies also tend to be more affordable than fully modular units, making them an attractive option for those seeking more flexibility than non-modular units offer without the additional cost associated with fully modular models.
Fully modular power supplies offer the highest level of flexibility when it comes to installation and cable management. As the name implies, all cables on a fully modular unit are detachable, allowing you to utilize only the necessary cables. This results in a cleaner and simpler installation process, free from excess cables obstructing the way. Additionally, fully modular units provide the freedom to use cables that are more appropriate for your specific build. For instance, if you don’t require two GPU cables, you can remove one and replace it with an extra SATA power cable to accommodate additional storage. Fully modular units often boast more features compared to non-modular or semi-modular units, targeting enthusiasts who are willing to pay extra for those added functionalities.
Nevertheless, the advantages of a fully modular PSU may not be as relevant to budget-conscious buyers. It is recommended to consider fully modular units only if cable management and flexibility are significant priorities for you.
