• Caution: Bitmain’s product warranty does not cover damages caused by overclocking, even when overclocking is enabled via Bitmain’s hardware and/or software.
• Bitmain recommends Bitmain original PSU
• Caution: Wrong input voltage may probably cause miner damaged and shall not be covered by the warranty.

Operating Condition

Max ambient temperature 45°C, altitude 0m.

Usually, when the miner is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1℃ for every increase of 300m.

Caution: Keep your Hash boards below 70°C degree temperature for optimal life-time of the ASIC Miners.

• Damage caused by poor power supply, lightning or voltage surges
• Burnt parts on hash boards or chips
• Boards/components damage due to water immersion or corrosion due to wet environment
• Bitmain’s product warranty does not cover damages caused by overclocking, even when overclocking is enabled via hardware and/or software.

If one of the cases above happens, you shall not be able to claim the warranty. For any specific procedures, please refer to the after-sales process.
