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.

Please note: While all units meet the guaranteed hash rates, slight variances may occur from batch to batch. Power consumption might also vary depending on components like fans or power supplies. This approach allows me to secure the lowest pricing possible for you. Rest assured, each unit is vetted for performance!

⚠ 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.

Summary

The Bitaxe Gamma Supra 403 offers an ultra-low-power entry point into SHA-256 mining for users focused on efficiency, experimentation, and network participation. When operated within recommended specifications and proper environmental conditions, it provides reliable performance in a compact, open-source design.
