Notes
(1) The hashrate value, power on wall, and power efficiency on wall are all typical values. The actual hashrate value fluctuates by ±3%, and the actual power on wall and power efficiency on wall fluctuate by ±5%.
(2) Caution: Wrong input voltage may cause server damaged.
(3) The noise is loudest when the fan is under maximum RPM(rotation per minute).
(4) When the server is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1℃ for every increase of 300m.

Comparison with CK-Box
The Goldshell CK-Box II differs from the original CK-Box in several ways. It offers higher hashrate, potentially leading to greater mining rewards, while also having energy-efficient modes. It has a more advanced design, being more compact and likely quieter with a noise level of ≤ 35 dB. The advanced dashboard provides better monitoring. Both use the Eaglesong algorithm, but the CK-Box II may have better optimization for certain cryptocurrencies and offers more operating mode options, allowing users to choose based on their needs and electricity costs.
