In this issue, let's talk about the heat dissipation problem of the power supply, including the importance of heat dissipation, the heat dissipation method, the main heating components inside the power supply, and the requirements of the upper temperature limit of each key point.
 
First of all, understand the current user's awareness of power supply cooling: the majority of DIY users have a high degree of attention on CPUs, graphics cards, motherboards and other accessories that can directly affect the performance of the whole machine. However, the power supply has not been given enough attention, and the quality of the power supply is not very concerned. I always feel that the wattage is almost enough. But the role of the power supply is actually very important, definitely not lower than the CPU, the stable operation of the entire power supply depends on the power supply to support. The consideration of power supply cooling is mainly due to the heat dissipation requirements of the entire chassis. They tend to pay more attention to mute, and the price is not low.
 
The number one killer of the power supply --- high temperature
 
A complete power supply consists of a housing, a fan, a circuit board with various electronic components plugged in, and a power outlet. The basic working principle of the power supply is to convert the high-voltage alternating current into the different low-voltage direct current required by the computer through the high-frequency switching technology. In the AC--DC conversion process, due to technical limitations and the electronic components themselves have a hindrance to the current, a certain part of the energy becomes heat energy, which is emitted into the air in the form of heat, giving the impression that it is high temperature. When the power supply is operated under high temperature conditions, the performance will be reduced compared with normal temperature, which is reflected in the reduction of output power. This is because high temperature affects the accuracy and stability of electronic components, as well as the resistance, capacitance, and inductance of various electronic components. Sometimes the electronic parts are damaged, which makes the power supply work abnormally or not working.
