Power supply unit for Whatminer M20S/M21S

Whatsminer M20/M21S P21 PSU Power Supply Unit

Each ASIC operates using chips installed on hash boards, but it is impossible to start the mining process without a power supply unit. Some companies sell their equipment with a PSU included, while other manufacturers only sell ASICs, and users have to find a powerful unit for effective mining. The power supply unit is an important piece of equipment. It takes on the maximum load during prolonged mining when connected to the network in high temperatures. Many developers install a built-in 15-21 volt power supply to maintain a high hash rate. Keep in mind that installing custom firmware in an attempt to overclock the ASIC may cause it to malfunction. By using equipment with a separate power supply, you can quickly replace the unit during repairs if it is damaged, and if it breaks down completely, simply replace it with a new one and continue mining digital coins. When using ASICs with built-in power supplies, the mining process will have to be postponed during repairs, as time will be needed to carry out repair work at a service center. If you detect malfunctions in the device, you should contact the service center and not attempt to repair the power supply yourself if you do not have experience and special tools. If it breaks down as a result of mechanical impact, it should be replaced with an original component from the manufacturer.
