Before you order
- Match the model: Whatsminer PSUs look alike but differ by output voltage; compare the full model code on your original PSU label (P221B, P221C, P222B, P222C) and send us a photo of it if in doubt.
- Diagnose first: confirm the PSU failure before buying, and never power up or open a damaged power supply.
- Installation: a professional miner PSU for 220–240 V, not a device for a 120 V household outlet; it takes the miner’s C19 power cord.
- Free US shipping; defects reported within 7 days of delivery are covered under our policy for new spare parts.
