Estimates use the live BTC/ZAR price and current network hashrate, a block reward of 3.125 BTC, and 357 TH/s @ 4,785 W per miner. Real returns vary with difficulty, price, pool fees and uptime. Figures are indicative, not a guarantee.

Before you order

Power requirements

To install at your home, your electrical supply must meet these requirements. Not sure what you have? Contact us and we'll help you check.

You must have a 3-phase power supply

Installation requires a 3-phase connection with the correct copper cable to your distribution board. Cable is sized for the miners only — this is over and above your normal household usage. Each Antrack V1 takes up to 4 miners.

1 rack (4 miners): 16 mm²
2 racks: 25 mm² min
2 racks with ease: 35 mm²
Supply: 3-phase

Cable sizes are copper and cover the miners only — they don't include your house load. Running more than 2 racks? Contact us and we'll size the cable for your setup.
