1. First of all, calculate the maximum power consumption of the computer
The power consumption of the computer is different in different operating states, such as 95W on startup, 35W on standby, and up to 480W when the game is fully loaded.
The power consumption of the power supply is changed according to the operating needs of the computer, assuming that the standby power consumption is 35W, then in the standby time, the fan is too lazy to turn, and it is 35W/h/conversion rate in an hour, and violent games, high load of the graphics card, it is possible to reach higher power consumption.
A car that can pull 10 tons of cargo does not mean that it will consume the same gasoline for empty and light loads.
2. Power conversion rate and standby power consumption
Usually the better the quality of the power supply, the less attenuation of the conversion process, the higher the conversion rate, United States there is also an 80plus, the same brand, power supply because of the PLUS level is different, the power conversion rate and price will be very different, there are many false standards, the big brand false standards are relatively less, which is why not introduce miscellaneous brands;
The conversion rate of the power supply is different under different loads, usually in the 40%-60% range of the power supply conversion rate is the highest, which is why it is recommended to buy a power supply with a slightly larger total output, the first is to use the best conversion rate, and reduce heating, fan noise, and reduce the probability of capacitor bursting, and improve the service life of the power supply;
4. Output ripples
Ripple and noise are mixed AC components in the DC output of the power supply, and if you look at it with an oscilloscope, you will see that the voltage fluctuates slightly up and down, like water ripples, so it is called ripple. Excessive ripple will interfere with the digital circuit and affect the stability of the circuit operation. Generally, the solid-state capacitor of FPCAP is filtered to reduce ripple interference, which is often used in many high-end headphones in the past.
5. Wide range of voltage support
The voltage in some areas is not stable, if there is no voltage regulator installed at home, the voltage difference between the peak power consumption period during the day and night may be more than 10V, sometimes turning on the air conditioner at night will cause the lamp to lose voltage and shine, if the voltage is not widely planned, some voltage fluctuations may lead to a lack of power supply for a spare part to produce a blue screen restart, the game is good, and the sudden restart is often the reason, this may be the most important thing for Lao Tie.

The cause of inverter heating - Delta inverter
1. The problem of the inverter and the motor itself
If the motor has been used for a long time, it is not good to clean the insulation function, or the bearing may be stuck, and it may show a large current and heat. The coupling between the motor and the load may also be worn, or the motor is unbalanced, the fixtures of the motor are loose, etc.
