Product Details

Bitaxe Supra Hex 701 4.2TH Six Chip Open Source Bitcoin Solo Miner at 90W

Six BM1368 ASIC chips where the Gamma 601 uses one. That is what "Hex" means, and it pushes the Supra Hex 701 to 4.2 TH/s at 90W. The most powerful Bitaxe model and the most capable open source Bitcoin miner ever produced. Solo mining against Bitcoin's 600+ EH/s network. The odds of finding a block are astronomically small, but the cost to play is $0.15 per day. Open source hardware with PCB designs on GitHub. 4.2TH/s at 90WW and 35dB dB. Standard outlet compatible worldwide. 10 x 6 x 5mm at 0.4 kg. Ethernet connectivity. 5 - 45 °C operating range. Universal 100-240v. The solo mining community has documented real block finds with similar hashrate devices. Improbable but not impossible. The financial exposure is measured in single digit dollars per month. For buyers evaluating this model: total cost of ownership equals acquisition price plus electricity ($0.15 daily at $0.07 per kWh) over your planned deployment. Compare that total against expected Bitcoin mining revenue at 4.2TH/s and current network difficulty. The model producing more coins per dollar invested at your specific electricity rate delivers the best return. The entire Bitaxe project runs on open source principles. PCB layouts, schematics, firmware source code, and manufacturing files live on GitHub. Anyone can build, modify, or improve the design. The Supra Hex 701 represents the community pushing the platform to its current limits: six chips, 4.2 TH/s, still under 100W and silent. Daily electricity at $0.07 per kWh: $0.15. Annual: $55.12. The cost to operate the most powerful open source Bitcoin miner ever made is less than a monthly streaming subscription.
