The A9+ ZMaster is outdated. Newer models make Zcash far more cheaply.
The A9+ ZMaster produces 120 kSol/s of Equihash hashrate and consumes 1,550 W.
The A9+ ZMaster measures about n/a and weighs around 11 kg.
The A9+ ZMaster is air-cooled with fans. In the UAE we run air-cooled machines in immersion tanks instead, which keeps them cool in desert heat.
We can host the A9+ ZMaster in UAE (6.0¢/kWh, 99.3% uptime, immersion), Nigeria (3.9¢/kWh, 73.6% uptime) and Argentina (6.0¢/kWh, 98.7% uptime). The Zcash it mines goes straight to your own wallet.
Innosilicon announced the A9+ ZMaster in Jan 2019.
