Power Supply for Whatsminer M20S and M21S

The AFRNDK P21 delivers up to 3300W of continuous power with a 12V output rated at 240A. It accepts an input range of 185V to 300V at 50Hz or 60Hz and operates from -10°C to +50°C.

Ten 6-pin buckle terminals and built-in protections

Ten standard P6 connectors supply multiple hash boards simultaneously. Short-circuit, over-current, over-voltage and over-temperature safeguards shut the unit down before damage can spread. Peak efficiency reaches 93% under load.

Suits miners replacing a failed Whatsminer PSU

Technicians restoring M20S or M21S rigs can swap the unit directly after confirming the exact model with engineering support. Operations needing different voltage rails, connector counts or a wider input range should evaluate alternative power supplies.

Frågor om den här produkten

Will this PSU work with a standard 185–300 V supply?

Yes, the input voltage range is 185–300 V at 50/60 Hz, so it accepts common single-phase mains within that window.

Can it power a Whatsminer M20S or M21S without extra cables?

It includes ten standard 6-pin buckle terminals (P6) rated for up to 300 A total, matching the connectors used by those miners.

What protection features are built in?

The unit provides short-circuit, over-current, over-voltage and over-temperature protection to shut down safely under fault conditions.
