The power supply is a main powering unit for the normal operation of the ASIC miner. If the power supply of the miner is damaged, the miner will not be able to be turned on, the fan will not rotate, and the power supply will be repeatedly shut down and then restored. Therefore, it is very important to learn the basic principles and maintenance methods of the power supply. The Bitmain PSU repair course mainly introduces the troubleshooting methods of various power supply failures and how to use test tools to accurately locate them.
