The main difference between full-module and half-module power supplies lies in the range of wire plug-in capabilities, which in turn affects the difficulty of wire management, the cooling performance of the case, compatibility, and cost-effectiveness. The specific differences for different budgets and assembly requirements (especially for gaming computers) are as follows: 

Definitions and Structures 

All the cables of the full-module power supply are detachable and are connected to the power module through the module interface. Users can choose the cables they need based on actual requirements, avoiding unnecessary cable accumulation and improving the tidiness and air circulation efficiency inside the case. For the semi-module power supply, some cables are fixed, usually including necessary cables such as motherboard power supply and CPU power supply, while the other part is detachable modular cables. This design not only ensures the convenience of basic connections but also provides certain flexibility to reduce redundant cables. The modularization degree of the full-module power supply is higher. Each functional module can be independently designed, tested, and replaced, making the maintenance and upgrade of the power supply more convenient. 

Comparison of advantages and disadvantages 

The advantages of full-module power supply are high customization, better heat dissipation, ease of upgrade and maintenance. The disadvantages are higher cost and increased installation complexity. The advantages of semi-module power supply are moderate cost and simple installation. The disadvantages are that cable management is not as flexible as that of full-module and there are limitations during upgrade and maintenance. 

The full-module type is "no default cables, all connections made by yourself", while the half-module type is "core cables must be included, others are optional" - both of these are more suitable for organizing cables compared to non-module power supplies (where all cables are fixed), which is why modular power supplies are preferred for gaming computers (tidy cable management = smooth airflow in the case = better hardware cooling, preventing system crashes under high load). 

Applicable scenarios

The full-module power supply is suitable for high-end gamers, large workstations, and systems that require frequent upgrades and maintenance. The semi-module power supply is more suitable for ordinary users with limited budgets but still hoping to achieve some flexibility in cable management, as well as for mid-range computer systems.
