When building your PC, choose a modular power supply for efficient cable management. Modular PSUs allow you to remove unused cables, enabling personalized cable organization tailored to your needs.

This feature not only keeps your PC case tidy but also improves airflow, essential for maintaining optimal performance and temperatures. In contrast, non-modular power supplies come with fixed cables, which can create a cable mess and impede airflow within the case.

Opting for a modular PSU simplifies installation as you can select only the required cables for your setup, unlike non-modular PSUs that may demand more effort to handle excess cables effectively.

Your decision between modular and non-modular power supplies hinges on your preference for customized cable management and the level of installation ease you desire in your PC build.

PSU Form Factor and Compatibility

Understanding the physical size and shape of a power supply unit (PSU) is crucial for compatibility with different PC cases. PSU form factors like ATX, SFX, and TFX determine the dimensions and design, ensuring a proper fit and efficient airflow management within your build. Selecting the right form factor is essential to prevent issues like space constraints, cable management difficulties, and component interference. For instance, the compact SFX-L form factor provides extra depth for stability in small builds, offering flexibility in small form factor PC configurations.

Form Factor Dimensions Common Case Compatibility
ATX Standard Most Mid to Full Towers
SFX Small Small Form Factor Cases
TFX Thin & Long Compact Desktop Cases

Noise Levels and Cooling Efficiency
