Whatsminer M50 Conductive Copper Sheet for P221B / P222B PSU
The Whatsminer M50 conductive copper sheet is the high-current busbar that connects the Whatsminer P221B and P222B power supplies to the hashboards. It carries the full DC current to the hashboard and is a mandatory part of the miner-to-PSU electrical path — without it, the chassis cannot complete the power loop.
Build is high-quality copper with strong oxidation resistance for long service life. Once a copper sheet is bent, oxidised at the contact patch or burnt, it cannot be repaired — only replaced. Stock spares for rebuild lines and field service kits.
Typical Use Cases
- Damaged copper sheet replacement — burn marks, cracks, deep oxidation at the contact patch.
- PSU swap during rebuild — fresh sheet when replacing a P221B / P222B PSU.
- Loose contact resistance fix — high-power section heating because of bad copper-to-pad mating.
- Production refurbishment — bulk inventory for M50 rebuild lines.
