We will analyze six major Equihash mining devices. They are Bitmain’s Antminer Z9, Z11, and Z15, as well as Innosilicon’s A9 ZMaster, A9+ ZMaster, and A9++ ZMaster. Let’s take a look at their specs, power consumption, and current profitability.
Antminer Z9 Specs
Antminer Z9 is a beginner-level ASIC device by Bitmain released in September 2018. Here are Antminer Z9’s main specs.
- Algorithm — Equihash
- Power consumption — 1150 W ± 10%
- Hashrate — 40.8 kh/s ± 5%
- Dimensions — 132 x 226 x 279 mm
- Weight — 5.5 kg
- Noise level — 76 dB
- Fans — 2 pcs, 12 V and 2.4 A each
- Voltage — 11.6-13 V
- Interface — Ethernet
- Operating temperature — 5-45°C (41–113°F)
What to Mine on Antminer Z9
Like with other ASICs that support Equihash, the choice is between Zcash ZEC and Horizen ZEN. There is also Komodo KMD, but its trading volume in the last 24 hours is equivalent to $1.5 million, which is rather low. So KMD owners might run into liquidity shortages if they want to sell a big sum of coins.
Let’s go to 2CryptoCalc and indicate a hashrate for the desired algorithm. The calculator shows that Horizon ZEC is the most profitable coin – mining would bring $0.65 per day (unadjusted for electricity costs).
Miners should calculate their net profit depending on their electricity costs. For example, Antminer Z9’s power is 1150 W, so it consumes 27600 Wh or 27.6 kWh. If you pay $0.08 per kWh, Antminer Z9’s operation will cost you $2.21/day.
So currently, mining on Antminer Z9 makes sense only if your electricity rate is around $0.02/kWh. If you are a fan of this cryptocurrency and ASIC, but your electricity costs are higher than that, it's easier to buy the coin on an exchange.
Antminer Z9 Mining Settings
If you can afford to mine Zcash ZEC, you should use the following settings for Antminer Z9:

Where to Download Firmware for Antminer Z9
Firmware is an essential part of ASICs used not only to add support for more coins but also to optimize their operation and fix bugs. As of the beginning of September, the latest Antminer Z9 firmware is ANTMINER-Z9-fixed-500M-201905171645.tar.gz from May 21, 2019. It is available on Bitmain’s official website.
You can also find alternative firmware options for Antminer online. For example, this firmware released in August 2018 helps to…
