Product Overview

The Goldshell CK-Box II is an innovative and efficient ASIC miner with the Eaglesong algorithm as its core, targeting the mining of Nervos Network (CKB). It has a hash rate of 2.1Th/s with 400W power consumption, which makes it the kind of mining rig that falls between performance and energy-efficient. The small size of it and almost soundless (35dB) make it a perfect gear for home and small farm mining.Goldshell CK-Box II

Important Notes

  • Dual Operation Modes: Change two modes of mining, such as high performance (2.1Th/s) and the lower power (1.54Th/s) for the profit of your power.
  • Power Supply: Choose a 500W power supply (not included).
  • Cooling: Keep the device well-ventilated to ensure that the device can work properly.
  • Profitability Fluctuations: As CKB price and network difficulty change, the revenue may also change.

Why Buy the Goldshell CK-Box II?

For multiple reasons, the CK-Box II is the most attractive option among ASIC miners on the market for Nervos Network (CKB). The machine has a high hash rate while the power consumption is low. The user can save money and reduce the noise at the same time through the use of its dual operation modes. Even though the profit is heavily influenced by the market, the fact that it performs well and never occurs high-cost operations is quite convincing that it will generate a return on CKB investment.
