Computer Power Supply Selection Guide: Comparison of Different Types of Power Supply Units Introduction: When building or upgrading a computer, the selection of a power supply unit (PSU) is crucial. A good PSU not only provides stable power for various computer components, but also protects the computer from voltage fluctuations and power surges. This article will introduce various types of power supply units in detail and compare them to help you make a better choice. Types of Power Supply Units: 1. ATX Power Supply: It is the most common type of computer power supply unit. It is characterized by its compact structure, good cooling performance, and high efficiency. ATX power supplies usually have a variety of interfaces suitable for most computer hardware devices. 2. SFX Power Supply: It is a small design suitable for small chassis. Although its interface types are similar to ATX power supplies, due to its smaller size, it may be slightly inferior to ATX power supplies in cooling and power supply efficiency. 3. Modular Power Supply: The advantage of a modular power supply is that it allows customization of power cables according to actual needs, making the internal wiring of the chassis more tidy and convenient for user installation and maintenance. However, its price is relatively high.

Comparison of Different Types of Power Supply Units:

1. Price: Generally, the price of modular power supplies is higher, while common types such as ATX and SFX are relatively affordable. The 80 PLUS series is slightly more expensive due to its high efficiency and good stability. 2. Performance: Different types of power supply units have their own advantages in performance. For example, ATX and 80 PLUS series show excellent power supply stability and efficiency; while modular power supplies are favored by users due to their customizability. Although SFX power supplies are small in size, they can still meet general usage requirements. 3. Applicability: ATX power supplies are the first choice for most computers due to their wide range of interfaces and good compatibility; SFX power supplies are suitable for small chassis; modular power supplies are more suitable for users who pursue personality and customization; while the 80 PLUS series is suitable for users who pursue high performance and environmental protection.
