PSU_FAIL Critical

Whatsminer M30S – Power Supply Failure

PSU not responding

Critical — Immediate action required

Affected Models: Whatsminer M30S, M30S+, M30S++

Symptoms

  • Miner does not power on at all
  • No LED indicators
  • PSU makes clicking noise
  • No fan activity

Step-by-Step Fix

1

Check the power cord and outlet — ensure power is available.

2

Try a different power cord if available.

3

Check the circuit breaker — Whatsminer M30S draws 3400W+ and may trip a standard breaker.

4

If using a PDU, verify it can handle the load.

5

If the PSU makes a clicking sound, it is likely in overcurrent protection. Disconnect all hashboards and try powering just the control board.

6

Whatsminer PSUs are integrated — PSU replacement requires disassembly of the entire unit.

When to Seek Professional Repair

If the steps above do not resolve the issue, or if you are not comfortable performing these repairs yourself, professional service is recommended. Attempting advanced repairs without proper equipment can cause further damage.
