Digital currencies, which, these days, many people are aware of, are forms of electronic money transmitted in encrypted form over the internet. To extract these currencies, one needs devices and types of equipment. The Innosilicon A9+ Z Master Miner is mining hardware with the A9 ZMaster ASIC built into it and was released in January 2019 by Innosilicon.

First established in 2006, Innosilicon first manufactured processing chips. But with the outbreak of decentralized currencies, they started making mining devices. They are well known for the reliability and profitability of their mining hardware.


Physical Features

The Innosilicon A9+ ZMaster is a wonderful update from the previous series, Innosilicon A9 ZMaster, released around June 2018. The earlier models were well made and had high quality, such that they are still in demand. Also, the previous A9 model was about a home computer's size. The Innosilicon A9+ ZMaster uses a twin structure as if two miners are stuck together.

It comes with four fans and six hashes. This miner weighs around 11kg and has size dimensions of 155 x 250 x 360mm. The ZMaster uses a Local Area Network (LAN) ethernet connection for mining, and the wires adopt a buckle design that protects them from wear and tear.


Low Operating Costs

Whenever people see the Innosilicon brand on mining hardware, they immediately breathe a sigh of relief because the quality is worth it. The Hash Rate of the Innosilicon A9+ ZMaster is 120Ksol/s, double compared to the previous model, the A9 ZMaster. The power consumption is 1550W, and the input power is 12V. One feature against this miner is its noise level, which is about 75 dB, a bit noisier than the A9. This miner weighs 11kg, which isn't surprising considering the size.

When Innosilicon launched the A9+ ZMaster in 2019, many people thought it had a disadvantage of less hashing power than the Zeon 180Ksol/s, released the previous year. Although this is true, the Zeon miner isn't suitable for industrial-scale, whereas the A9+ ZMaster is. This feature makes the ZMaster more preferable.
