To quickly find the power supply of each chip on the motherboard, you can use the following methods:
< br >
Check the motherboard manual: If the motherboard has a manual, you can check the description of the motherboard chip in the manual to find the power supply of the chip you need to find.
Use the motherboard diagnostic card: The motherboard diagnostic card can detect various voltage, current and other parameters on the motherboard, and display it on the screen. Use the diagnostic card to quickly find the power supply of each chip.
Use a multimeter: Use a multimeter to measure the voltage of each pin on the motherboard, and the power supply end of each chip can be determined by measurement.
Use electronic circuit diagram: If the above methods are unable to find the power supply side of the chip you need, you can try to find the electronic circuit diagram of the motherboard, which will mark the pins and functions of each chip.
It should be noted that when operating, please first power off and ensure safety. If you are not familiar with the computer hardware, do not try to dismantle the machine for repair, so as not to cause damage. If there is a need for maintenance, it is recommended to hand it over to a professional.
1, you can refer to the power supply layout diagram of the motherboard or consult the technical specifications of the motherboard, these resources will indicate the power supply connection point of each chip on the motherboard.
2, in addition, you can use electronic test tools, such as a multimeter or power supply tester, to detect the power supply line on the motherboard and find the power supply end of each chip.
First, we can check the power supply of the motherboard through the BIOS(basic input\/output system). Press DELETE, F2, F10 and other keys to enter BIOS Settings, and then find power management or power supply options to check whether the voltage, current, power and other parameters are normal. In general, the motherboard should work in the standard voltage range of 12V, 5V, 3.3V, and the current and power should also meet the maximum support value of the motherboard. If the parameters are abnormal, replace the power supply or check whether the cable connection is loose.

Secondly, we can use hardware monitoring software to check the power supply of the motherboard. Common monitoring software, such as HWMonitor, CPU-Z, and SpeedFan, can read the sensor data on the mainboard chip, including the power supply value of the CPU, GPU, mainboard, and hard disk.
