Description

️ Spare Parts for Proto Miner Miners (819 & 400)

Designed for SHA-256 Bitcoin mining.

Available Components:

  • Hashboards:
    High-performance boards designed for maximum stability and efficiency. The Proto Miner 819 contains 9 boards, while the Proto Miner 400 has 5 boards. Replacing faulty ones with oProtoinal hashboards ensures the device restores its full hashrate capacity (819Th/s or 400Th/s depending on the model).

  • Cooling Fans:
    Built for continuous operation in mining environments. The Proto Miner 819 comes with 6 high-speed fans, while the Proto Miner 400 operates with 4 quieter, low-noise fans. OProtoinal fans help maintain optimal operating temperatures (5 – 45 °C) and extend the miner’s lifespan.

  • Power Supply Units (PSU):
    Reliable and efficient power solutions made for nonstop operation. The Proto Miner 819 PSU delivers 12000W at 208–240V, while the Proto Miner 400 PSU provides 6000W at 208–240V. Both ensure stable power distribution, high conversion efficiency, and overload protection.

✅ Using genuine spare parts guarantees long-term stability, reduced downtime, and protection from overheating or electrical issues.

⚡ Important: To ensure compatibility, please contact our support team and provide your miner’s serial number before ordering spare parts.
