Bitaxe Supra Hex 703 - 4.2 TH/s Open-Source Bitcoin Miner

The Supra Hex 703 is the six-chip step up in the open-source Bitaxe line. Six BM1368 ASICs share a single air-cooled board, so you get a meaningful jump in hashrate over the one- and two-chip Bitaxe boards while the machine still runs from a standard desktop power brick and sits on a shelf without a rack.

Everything about it is inspectable. The hardware design and the firmware are both open source, the web interface exposes pool settings, frequency and voltage, and the device reports hashrate, chip temperature and fan speed in real time. That makes it a common first choice for people who want to run their own node and point a miner at it rather than hand control to a hosted service.

Safety and intended use

This is specialised computing hardware for hobbyist and enthusiast use. It generates continuous heat and requires unobstructed ventilation, a suitable electrical supply and a stable surface clear of flammable material. It is not a household appliance and is not intended for use by children. Confirm that your circuit can carry the load continuously before installing, and never obstruct the intake or exhaust.

Mining hardware is sold as equipment only. Network output depends on factors outside our control — network difficulty, pool selection, firmware configuration, ambient temperature and your electricity tariff — and we make no representation about financial returns of any kind. Please read our Risk Disclosure before purchasing.
