The SFX power supply is suitable for use in miniaturized computer systems, especially for those high-performance desktops that use core-compatible mini-ITX or Micro-ATX motherboards, or for users who need to save desktop space. It is particularly suitable for low to medium power consumption desktops that prioritize portability and space utilization, and can also meet the needs of some small-scale gaming desktops. 

Mini case: Due to the small size of the SFX power supply (125×63.5×100mm), it is suitable for installation in compact cases. These cases are usually used in conjunction with Micro-ATX motherboards, saving desktop space. 

Mini Supercar Mainframe: In recent years, more and more DIY enthusiasts have favored building Mini Supercar mainframes. Their compact size not only takes up less space but is also easy to move. SFX power supply is an ideal choice for these mainframes. 

Small systems with high power requirements: Although SFX power supplies are limited in size, some manufacturers such as Zhenhua have launched high-power SFX power supplies, including versions with gold and platinum conversion efficiencies, with a maximum power of up to 1000W, suitable for high-performance small systems. 

It should be noted that when choosing an SFX power supply, factors such as the rated power, conversion efficiency, and heat dissipation design of the power supply need to be considered to ensure that it can meet the power supply requirements of the system and maintain good heat dissipation performance. In addition, the SFX-L power supply (extended version) has a better heat dissipation effect as it can accommodate a 120mm cooling fan, making it suitable for users who are sensitive to noise and heat dissipation performance. However, it has a relatively higher price. 

For low-power hosts mainly used for document processing, web browsing, and audio-visual entertainment, the 300W-450W models of the SFX power supply can fully meet the power supply requirements. When paired with micro-ATX or mini-ITX motherboards, they can be used to build compact desktop computers, saving office and home space.
