This applies to all Antminers.
1. Check your voltage.
If your voltage is below the starting voltage of the PSU, the PSU will not work, resulting in miners not powering up. Starting voltage is the required voltage of wall outlet to get your PSU working.
The voltages differ by country. Most countries are either 110 V or 220 to 240 V, and the different voltages will put out different power.
Make sure that your country delivers a voltage for the PSU that can be converted into sufficient power for your miner.
Generally, if your miner requires more than 1200 W of power, your wall socket must deliver a voltage of 220 V. If your country do not supply electricity at 220 V, you may consult an electrician to get your wiring configured.
While our PSU deliver the same performance, there are some slight differences in terms of the rated power and input voltage. Do check their specifications for more details.
2. Check the PSU.
To check the PSU, you can test the miner with a known, working PSU and see if the working one could power up the miner instead.
If the other working one could the power up instead, this PSU is not working well.
You can use the below page to troubleshoot the PSU:
3. Check the control board and then hash board.
If you still cannot power up the miner, disconnect all the cables to hash boards as the photo shown below, then only connecting a power connector to the control board.
