Installation and Operation

After connecting and configuring the equipment, you will realise two things. First, the AvalonMiner 741 – 7.3 TH/s is not as noisy as most competitors in the market. It produces a sound similar to that of a quality fan functioning at higher power. Secondly, the cooling system allows the product to function at relatively lower temperatures (around 60 degrees Celsius).

The Avalon software is also easier to use due to the friendly graphical interface. To start mining, click the “Settings” tab, enter your favourite mine pool’s information and save the data. After that the AvalonMiner 741 – 7.3 TH/s will start working automatically.

At the start, the AvalonMiner takes several minutes to reach its par processing speed. You will easily see that on the graph in the miner’s simple configuration panel. In addition to displaying general data, the product also displays the extractor’s revolution speed with several updates per every second.

And to help you check the equipment’s status, the manufacturer has included a number of lights. On its front, the product features a LED that changes to yellow, white, red or blue to indicate that it is working properly, is at rest, failing or overheating respectively. The lights on its processing cards might change red or green to indicate that they are badly fed or good. Its interface might also display green, blue or red lights to indicate the connection status to the controller.

Cost effectiveness

On average, the product has a processing speed of 7.3 TH/sec. Therefore, it can generate about 0.00308 BTC per day. That is equivalent to $7.31 per day with the current exchange rate in countries where the price of electricity is almost zero. Considering the purchase price of the mining equipment, the controller and the shipping cost and assuming that the difficulty of Bitcoin mining will not change, you will return your investment within five months.

In situations where electricity does not represent fictitious and significant costs and where the difficulty of Bitcoin mining does not increase, the condition will be optimal. The AvalonMiner 741 – 7.3 TH/s is likely to reach the return on investment (ROI) within 5 to 8 months. The time is reasonable in crypt coin mining. Everyone agrees that Bitcoin mining is no longer a risky investment. It is a valuable investment.

Final Words

Antminer S9

Some years ago, you could mine Bitcoins using a gaming GPU. However, after the addition of mining firms and increase of individual miners to the global mining pools, mining possibility has vanished – GPU’s cannot deliver the Bitcoin hashrate you need to make profits. That is the main reason why the China based company, Bitmain, started developing a set of ASICs which are accessible to casual miners. Furthermore, the ASICs have a reasonable return on investment. In other words, with their machines, the common men can start mining Bitcoins today. Apart from the Antminer S9 ~13.5TH/s @ .098W/GH 16nm ASIC Bitcoin Miner, the company supplies other machines such as the S7 and the S5. So, what is Antminer S9?

Impressions of the Antminer S9

The product’s square tube housing measures 14 cm and also serves as an extra heat sink. The body features longitudinal three hash boards blown by two fans. The turnover of the blow fan is 10-15% higher and it therefore allows more efficient passage of air.

Hashing of the board 63 is situated on the product’s chip ASIC BM1387 and produces 74 TX/s capacities at 650MHz frequency. Every chip features two aluminium radiators on both sides of the board.

One problem you are likely to identify immediately the product starts running is the noisy fans. It is unclear why the producer settled on such power. If the miner works full-time, the fan is likely to produce 75dB noise. Therefore, it might not be suitable for individuals who want to mine Bitcoins while still in their homes. However, you can still consider the less noisy fans available in the market.

The other impression from the Antminer S9 ~13.5TH/s @ .098W/GH 16nm ASIC Bitcoin Miner relates to performance. After several weeks of use, you may add the device to get a stable system that is undemanding to most external conditions and one that is easier to setup like the previous Antminer series. Slight temperature increase is unlikely to affect the product’s performance.

Power supply

After purchasing the Antminer S9 ~13.5TH/s @ .098W/GH 16nm ASIC Bitcoin Miner, you will not just plug it into your wall socket to start mining. You will need a power supply unit (PSU). Therefore, during your purchase, you will have to budget for the PSU, which will cost you additional $150. The manufacturer recommends the APW3-12-1600-B2 which you can get on their website.

However, if you have a power supply of old Bitcoin miner, you can also use it. A quick example: the EVGA SuperNova 1300 Watt GPU PSU will also work with the product. But if you do not have any compatible PSU, it is better if you stick to the manufacturer’s recommendation. The product will not cost you more than the other old PSUs available in the market.

Installation and operation

The Antminer S9 ~13.5TH/s @ .098W/GH 16nm ASIC Bitcoin Miner is amazingly easy to setup. After you have purchased a power supply, you will just need to connect it to the Bitcoin miner. The Antminer S9 features 9 connectors on the machine and one on the board. Before plugging it into the power outlet, ensure that you have switched off the power supply switch. Start by plugging the power supply into the Bitcoin miner and connect it to the wall. Proceed and plug in your Ethernet cable. After you have properly setup everything, check your cable connections and switch on the power supply.

Now, you should continue and plug the system into the internet to generate an IP address. For configuration purposes, use your internet browser to log into the new IP address. You can use IP Reporter and copy your Antminer IP into the web browser bar. Before turning on the Bitcoin miner, you should ensure that the IP Reporter is running on your personal computer. The username and password should be root (lower case ‘r’) by default. Now, check the Bicoin miner’s speed. That includes the core temperature, the frequency and the hashing speed.

Bitmin Antminer S9

The Bitmin Antminer S9 ~13.5TH/s @ .098W/GH 16nm ASIC Bitcoin Miner might be the strongest Bitcoin miner in the market. The product outputs 13.5TH/s, which means that you will get between $4.56 and $5.80 worth of Bitcoins per day. That highly depends on your electricity cost. If your electricity cost is below $0.10/KWh, you are more likely to earn $2,150 per year, which is almost double the price of the Bitcoin miner. To start using the product, you will also need a PSU. The recommended PSU has a price tag between $300 and $400. There are no other costs and therefore, you should expect to spend around $1550, when buying from the official site.

The resulting return on investment (ROI) of the Bitcoin Miner plus the recommended power supply is around 7-8 months if the electricity cost is below $0.10 per KWh and around 18-20 months if the electricity cost is below $0.20 per every KWh.

However, as you might expect with cryptocoin mining, the total income will highly depend on the mining difficulty. The mining difficulty level depends on the number of people mining the coins simultaneously. And because many people are buying Bitcoin miners, the mining difficulty is expected to rise. Do not worry! The price of Bitcoins is also increasing. For example, people spent $0.08 per every Bitcoin in the year 2010. In 2017, the amount hit $1,250.

Even though you cannot easily tell the price of the Cryptocoin some years to come, it is evident that the price will constantly rise for a while. That is due to several factors such as the coins growing popularity. Many people are using them to pay for goods and there are numerous platforms where people exchange them for paper currency. And because of the difficulty in mining, the coins are likely to grow in value.

Final Words

If you are planning to get into the Bitcoin mining world, the Antminer S9 might be the only available logical solution. However, to buy the product, you will have to consider the amount of money you want to invest in Bitcoin mining, where you are currently living (the cooling costs and the electricity cost) and the expected growth of Bitcoins value. What’s more, you have to consider the ever increasing mining difficulty and the durability of the Antminer S9 ~13.5TH/s @ .098W/GH 16nm ASIC Bitcoin Miner. Generally, the product becomes obsolete within 8 to 12 months.
