Safety & Usage Notes

 

 

This product is specialized computing hardware intended for experienced users and hobbyists. It generates heat during normal operation and requires proper ventilation, appropriate electrical setup, and safe operating conditions. Do not operate near flammable materials and ensure airflow is not obstructed. This product is not a consumer household appliance.

 

For additional details, please review our Safety & Usage Information page prior to operation.

⚠ Overclocking Warning

 

 

Overclocking increases power consumption, heat output, and overall stress on components. Operating the miner beyond recommended specifications may void the manufacturer warranty and can result in reduced hardware lifespan, permanent damage, or unsafe operating conditions if proper ventilation and electrical setup are not maintained. Excessive heat may increase the risk of damage to surrounding equipment or materials. Overclocking is performed entirely at the user’s own risk and is not recommended for beginners.

 

Stock units include a power supply designed for operation at factory-recommended settings. Operation beyond stock specifications may require a higher-capacity or upgraded power supply to safely support increased power demand. Operating an overclocked miner with an undersized or inadequate power supply may lead to instability, hardware failure, or unsafe operating conditions.

Additional Notes

 

 

Mining is probabilistic in nature. Results are not guaranteed and depend on network difficulty, hashrate, and time.
