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.
