ATX power supply is a standard for computer power supply. The power and specifications of ATX power supply are the basis of computer power supply design and have an important impact on the stability and performance of the computer.
Power specifications of ATX power supply
The power specification of ATX power supply refers to the output power of the power supply, generally in watts (W). According to the power specifications of ATX power supply, it can be divided into the following types：
200W: suitable for low-power computer systems, such as office, Internet, etc.
300W: suitable for medium-power computer systems, such as home entertainment, games, etc.
400W: suitable for high-power computer systems, such as professional graphic design, video editing, etc.
500W and above: suitable for high-performance computer systems, such as servers, workstations, etc.
Efficiency specifications of ATX power supply
The efficiency specification of ATX power supply refers to the proportion of electrical energy that the power supply can convert into useful electrical energy in the process of converting the input AC power into DC power. According to the efficiency specifications of ATX power supply, it can be divided into the following types：
80 PLUS: The power supply efficiency reaches more than 80%.
80 PLUS Bronze: Power efficiency reaches more than 82%.
80 PLUS Silver: Power efficiency reaches more than 85%.
80 PLUS Gold: Power efficiency reaches more than 87%.
80 PLUS Platinum: Power efficiency reaches more than 90%.
Features of ATX power supply
High efficiency
ATX power supply adopts advanced circuit design and components, and has the characteristics of high efficiency. High-efficiency power supply can reduce the loss of electric energy and improve the stability and performance of computer system.
Low noise
ATX power supply adopts high-quality fan and silent design, and has the characteristics of low noise. Low-noise power supply can reduce the noise interference of computer system and improve the user experience.
High reliability
ATX power supply adopts strict production and testing process, and has the characteristics of high reliability. High-reliability power supply can reduce the failure rate of computer system and extend the service life of computer.
Good compatibility
ATX power supply adopts standard interface design and has good compatibility. Good compatibility can ensure the normal connection and operation of power supply with motherboard, hard disk and other devices.
How to choose an ATX power supply
Choose the power specification of the power supply according to the power consumption of the computer
When choosing an ATX power supply, the power consumption of the computer should be considered first. If the power consumption of the computer is high, a power supply with a larger power should be selected to ensure the stable operation of the computer system.
Choose the efficiency specification of the power supply according to the efficiency of the power supply
When choosing an ATX power supply, the efficiency of the power supply should also be considered. A high-efficiency power supply can reduce the loss of electric energy and improve the stability and performance of the computer system.
Choose the brand and model of the power supply according to the certification of the power supply
When choosing an ATX power supply, you can refer to the certification of the power supply. Power supplies with certification are more stringent in design, production, testing, etc., and the quality is more reliable.
Choose the interface specification of the power supply according to the compatibility of the power supply
When choosing an ATX power supply, the compatibility of the power supply should also be considered. Choosing a power supply with a standard interface can ensure the normal connection and operation of the power supply with the motherboard, hard disk and other devices.
