ASIC miner Antminer S9 from one of the top brands Bitmain is considered a golden classic in the field of mining. For 2022, it cannot be called a “new product”, given the frequency of announcements and releases of new models, it still remains relevant and can be considered an excellent choice. Let's consider everything about Antminer S9, taking into account its profitability, competitiveness and relevance for 2022.
Antminer S9 is suitable for mining Bitcoin, BitcoinCash and other coins using the SHA-256 algorithm.
S9 is one of the most reliable and stable ASICs on the market. Top seller for 2022 and 2022. Antminer S9i is actually no different from AntMiner S9j; these are modified versions of the regular s9 with increased hashrate and reduced power consumption. A comparison of the two models will be below.
It’s worth clarifying right away that in 2022, mining of the most popular cryptocurrencies became industrial and for 95% of ordinary users (whose investments do not exceed $100,000), the most profitable format for investing in cryptocurrency is its direct purchase on the exchange. It is on the stock exchange, not in the exchanger because exchanges charge much lower commissions, provide maximum liquidity, and most importantly are safe to use.
The reliability of a cryptocurrency exchange is primarily determined by the trading volume and the number of users. By all key metrics, the largest cryptocurrency exchange in the world is Binance. The site has the largest cash turnover and supports transfers in rubles from Visa/MasterCard and payment systems QIWI, Advcash, Payeer .

Next, we bring to your attention a detailed review of ASIC Antminer S9 - technical characteristics, payback prospects and everything that may be of interest to potential users of this device.
Technical characteristics of Antminer S9
The ASIC miner Antminer S9 case is made of aluminum. This solution is a distinctive feature of all cryptocurrency mining devices produced under odd numbers by BITMAIN. According to the developers, this material is most suitable for making a case, as it allows for additional heat dissipation.
Specialized sleds are attached to the side of the case, allowing you to combine several miners into a horizontal stack. As before, hashing boards can be freely inserted into special slots in the housing without being additionally fixed.
| Algorithm | SHA-256 |
| Hashrate | 14.5 TH/s |
| Maximum overclocking | 17.5 TH/s |
| Consumption | 1350 watt (drain) |
| Chips | 189 x BM1387 (16nm) |
| Dimensions | 135x158x350mm |
| Weight | 4.2 kg |
| Noise level | high – 71db |
Main features and capabilities of the S9 model
S9 was conceived and implemented by Bitmain specialists as an energy-efficient tool for mining cryptocurrencies that operate using SHA-256. The most popular of them are BTC (bitcoin) and BCH (bitcoin cash). The ASIC case is made of aluminum and looks like an elongated rectangle with coolers located on the front and rear panels. This design solution provides excellent ventilation of internal working units: excess heat is removed by air flow using a minimum number of fans.
The top of the Antminer S9 serves as a platform for the Ethernet network controller, an SD card slot and two LED indicators. The internal content of the device consists of three parallel processor boards, each of which is connected to VM-1387 chips. Excess heat is removed through radiators installed next to the boards.
The main advantages of the S9 miner are excellent technical parameters and quality of components with compact dimensions and light weight. Thus, with an electricity consumption level of 1300 W, the system produces 13.5 +/- 5% HP, which is much higher compared to previous versions. The working base consists of 16-RM chips, which help increase the speed when calculating hash algorithms. A total of 189 chips, spread across three boards, combine to achieve a fantastic hashrate of 13.5 TeraHash per second, a result that would have been hard to believe just recently.
Meanwhile, the miniaturization of semiconductors in order to increase energy efficiency and computing power, within the framework of the technology used today, has almost reached its limit. Moore's law no longer applies because the growth in the speed of information transmission has slowed down, approaching the physical limit.
The 16nm manufacturing process used in the S9 is the most efficient upgrade from 28nm. And although 10nm chips are already on the way, the subsequent increase exceeds the boundaries of realistically possible values.
Briefly about the advantages of ASIC S9:
- better energy efficiency;
- high performance with small device sizes;
- full cooling;
- absolute autonomy of work;
- the ability to easily and quickly configure Antminer S9;
- unpretentiousness to external conditions;
- availability of Linux;
- the ability to fully update the Antminer S9 firmware in accordance with the usual official update procedures;
- highly efficient Bitmain power supply;
- Possibility of combining into a common farm.
Among the disadvantages of ASIC S9, it is worth highlighting increased noise. Initially, the device was developed for industrial use, so its authors did not take care of reducing fan noise. It is best to install the S9 in a separate room with a tightly closed door or replace the fans.
The device also has poor compatibility with most mining pools, with exceptions including Antpool and F2 Pool. Another disadvantage is the lack of a power supply included in the package (add another $170-$200 to the cost).
Pros and cons of Antminer S9
If we talk about the advantages of the S9, then first of all it is worth highlighting the following points:
- Still relevant for 2022 (even despite the greatly increased difficulty of Bitcoin mining + a huge drop in the cryptocurrency rate).
- Decent power, taking into account the ratio of hashrate, power consumption and cost of the device.
- Bitcoin mining - the SHA-256 algorithm is still considered the most promising and profitable due to the status and weight of Bitcoin.
- The cost of ASIC has dropped significantly compared to 2022 and 2018, so the device can be found at a bargain price.
There are also disadvantages of the device, although most of them can be considered conditional. They mainly concern the obvious features of many ASICs, which have retained their relevance by 2020. This concerns high power consumption and noise.
However, if you are not going to keep the S9 in living rooms, having allocated a special room for this (as is customary to do in most cases), noise can be called a conditional drawback. Moreover, at the moment, only a few models on the market can boast of moderate operating noise, so this minus applies to all ASICs rather than specifically to the S9.
Another disadvantage is the need to use an additional power supply. The installed power supply often overheats, especially when working on exchange pools (for example, NiceHash). Any server power supply will be suitable for these purposes.
It is also worth considering that when starting an ASIC (especially if it was bought secondhand, which is usually not recommended), you need to check:
- Power – the indicator should not be lower than 13.5 TH/s.
- No chip errors (in the Asic Status window, errors will be displayed as “X” instead of “0”. All chips should show “0”).
- Fan speed – basically, this indicator depends on the overall temperature in the room, so you shouldn’t pay much attention to this point (only if the ASIC is in hot rooms, which is undesirable).
How and where to buy Antminer S9. Price ASIC S9
Buying Antminer S9
Since the mining ecosystem does not stand still, and ASIC manufacturers are releasing competing models of mining equipment, it is not surprising that the price of Antminer S9 has undergone significant changes since the announcement of the design. So, initially its cost fluctuated around $2100, while now it has become more affordable. Although there are companies on the market that sell new ASICs at the same high level.
At the moment, Antminer S9 has already been discontinued, and therefore is not available for purchase on the official manufacturer’s website, but Bitmain offers for purchase an improved model called Antminer S9 SE at a price of $430.
As for prices in Ukraine and Russia for ASIC S9, the following picture emerges.
In Ukraine, ASIC is available on the following Internet sites:
- Rozetka (new) - 40,000 hryvnia ($1,600);
- ASIC FOX (used) - from 9945 to 10710 hryvnia ($390-420) depending on power;
- C-market (used) - 12699 hryvnia ($500);
- SETEVUHA (used) - 7000 hryvnia ($280);
- BitWallet (used) -11990 hryvnia ($480).
In Russia the choice is also quite wide. Distributors sell equipment both from stock and on order. Below are just a few of the companies selling ASIC S9:
- Dyckman Electronics Center, JSC (new) - 80,000 rubles;
- antminer-russia.com (used) - 19,500 rubles;
- SibStroy LLC (used) - 16,000 rubles;
- Impulse M LLC (used) - 15,490 rubles;
- IBMM (used) - 22545 rubles;
- CHINA STORE - 23,500 rubles.
Both new and used equipment can be found from sellers on the advertising platforms OLX in Ukraine and Avito in Russia, in Telegram channels, YouTube channels, cryptocurrency forums, etc. There are more than enough proposals for this request. However, if you purchase an Asik S9 from an individual, you should remember that no one guarantees the integrity of the seller, and the transaction is carried out at your own peril and risk.
But even when purchasing Antminer S9 from a company, you cannot be completely sure that your purchase corresponds to what you want.
☝️
One of the methods of fraud in the industry is the sale of weaker Antminer S9 models under the guise of more powerful ones.
As a result, instead of Antminer with a power of 14 TH/s, in fact, you can become the owner of a 13.5 TH/s model. To implement the scheme, unscrupulous sellers re-stick stickers on all components of the structure. Thus, there is no question of visually detecting deception, of course, if the equipment is not in the hands of an expert. Therefore, to be sure of your purchase, it is better not to be lazy and send a request with the ASIC serial number directly to the manufacturer Bitmain for verification.
Power and cooling systems
As soon as information about the characteristics of the device became known, many users became interested in how much the ASIC S9 consumes per hour at such performance. Many also had doubts about the quality of the cooling system, because with such power it is very difficult to ensure good ventilation. At the same time, if coolers can still cool the system, then don’t they emit a strong hum? Let's look at the answers to these questions now.
A standard power supply designed for ASIC Antminer S9, depending on the power of the device itself, can have a power consumption level from 1127 to 1372 Wh.
According to data posted on the official portal of the manufacturer, this value can change up or down by 10 percent, depending on the load level. It has an ordinary case, typical for server power supplies, and is also equipped with ten 6-pin connectors. This quantity is enough to connect one ASIC C9, based on the following calculation:
- 3 connectors for each hashing board;
- 1 connector for control board.
In addition, there are special contacts for monitoring and control buttons that are initially closed.
The standard unit copes well with its functions and produces a voltage slightly higher than 12 V. This indicator is quite enough for the device to operate at default frequencies. The power supply is approximately 93 percent efficient, reducing heat and unnecessary power consumption. It is important to consider that this indicator is maintained only if the room in which the ASIC is used has a constant temperature of no more than 25 degrees. The main disadvantage of the power supply is the loud noise during operation created by the cooling system. It is capable of drowning out even the hum emanating from the miner’s fans.
If you simultaneously run several power supplies for one S9 ASIC miner, then it is important to take into account that each hashing board must be connected to no more than one power supply. Otherwise, the equipment may be damaged and the cryptocurrency miner will only have to enjoy the appearance of the aluminum case.
As in the previous model, Antminer S9 uses 2 fans with a diameter of 120 millimeters for cooling, the maximum rotation speed of which is 6 thousand revolutions. When creating them, the company's engineers were primarily concerned about the quality of cooling of the boards, and not about the noise level, allowing the device to be used at home. When the cooling system operates at maximum speeds, you can hear a piercing whistle, which makes it extremely unpleasant to be near the miner.
In this regard, it is recommended to optimize the cooling system for operating the device in an apartment or house. The fact is that for normal cooling of the Antminer S9 at a temperature inside the operating room of up to 40 degrees Celsius, a speed of 4 thousand revolutions is quite enough. Based on this, you can replace the cooling fans with ones that are less powerful and have a lower noise level. The ideal choice for this is the Delta AFC1212DE, which has the same dimensions as the standard models, but is characterized by quieter operation.
What does Asic Bitmain Antminer S9 look like?
The package consists of the device itself and a proprietary Bitmain unit with a power of 1600 W. Visually, Antminer S9 is not much different from other models from the manufacturer: the same aluminum case, fans on the sides and three hash boards with many chips. But there are still differences.
☝️
In Antminer S9, the number of chips located on each board is 63, for a total of 189 units.
The structure itself measures 350mm x 135mm x 158mm and weighs 4.5kg.
Appearance of ASIC Antminer S9 with power supply from Bitmain
Thanks to the unique sled ribs, it is possible to create entire farms by connecting equipment end-to-end.
Depending on the batch, the chips come with a clock speed of 650 MHz, or 600 MHz for newer designs in the lineup.
The same applies to the control module. In the older batch it is divided into two boards: black and green, while in newer batches there is no such division.
S9 payback for 2020
Bitcoin is currently experiencing its biggest drop in 2022, which is partly due to the hard fork in mid-May. Analysts firmly predict that this time is the most profitable period for the purchase of Bitcoin, which, according to forecasts, will begin to grow significantly by the beginning of July. Another powerful jump in the exchange rate is expected in the fall, by which time Bitmain will probably release the long-awaited S11 ASIC.
All this negatively affected the calculation of the S9's payback, if we evaluate it at the current exchange rate. With an average income of $6.3/day (excluding mining pool fees), your total monthly income will range from $180 to $190. With an average device cost of $1100-1250 (in new condition), the payback period is about 6 months. In the current conditions, this is quite promising, taking into account the fact that with an increase in the Bitcoin exchange rate in the second half of 2018, this period will be significantly reduced (up to 4 months).
For example, in the first quarter of 2022, S9 brought in $30 per day. By the beginning of April, this figure had dropped to $7.3/day. Of course, it is unlikely that profits in the second half of the year will increase to previous values given the increasing complexity of mining and other factors, but analysts fully admit that Antminer S9 can earn $10-10.5 per day.
Advantages and disadvantages of Asic Bitmain Antminer S9
Why Antminer S9 is good
The model is very popular due to its competitive hashrate, which provides excellent performance. Under certain conditions, such as low mining pool fees and minimal electricity costs, Antminer S9 is the most desirable miner in the crypto community. Compared to its predecessors, this model can bring a greater return on investment. Thanks to Bitmain's advanced technology, Antminer S9 is highly energy efficient compared to S7 and any other equipment released before it.
Advantages:
Competitive and extremely energy efficient model (still profitable to this day);
High build quality. The structure itself is well assembled and strong;
Good air circulation thanks to fans installed on both sides of the structure.
Flaws:
Expensiveness of the model. The cost of a new miner on the market can reach $2000. Such costs are not justified by the profitability of mining on this device, even with a free outlet. The payback period for a new model with free electricity can reach two years or more;
High noise level. This model is unlikely to be installed in a residential area, since the noise level from the structure is off the charts.
Preparing and turning on Antminer S9 for the first time
Before turning on the ASIC Miner C9, the user must place it in the most suitable place so that nothing obstructs the air exit from the blower fan. Due to the relatively low level of power consumption of the device, there are no special requirements for connecting it to the network. If there is no power supply button, it is recommended to use a surge protector equipped with a switch.
It is also important to understand the controller board, which is housed in a semi-open aluminum case.
This device contains the following elements:
- Card reader for an SD card required for flashing the miner. This may be necessary if the equipment does not start from the built-in memory.
- Reset button to reset settings to default values. It can be used if the connection is configured incorrectly or the miner is unavailable on the network.
- Normal and Fault indicators indicating normal operation of the miner or problems. The first one glows green, the second one glows red.
- Ethernet connector for connecting the cord.
- IP Report button for using BITMAIN's IP Reporter utility.
After checking that all connectors are connected correctly, the device can be turned on. During the first startup, the fans will run for a while at maximum speed. Thus, the system will independently clean itself of dust accumulated during storage or transportation.
If the connection is correct, the fan speed will decrease after a while, and the indicator on the Internet connection connector will begin to blink green. If you use a DCHP server, searching and setting up a subnet for the miner will be done quickly and without much effort.
To obtain information about the address assigned to the device, you need to visit the router's web interface and check the list of DHCP clients. To do this, the user can use a standard utility from BITMAIN called IP Reporter or use one of the network scanning programs.
When starting a proprietary utility, you must launch the software and click on the button labeled Start. At the same time, you must hold down the IP report button on the device for several seconds. After some time, the utility will detect the device and display its IP and MAC addresses.
After receiving the address, the user must enter it in the address bar of any Internet browser, after which it will automatically be moved to the web interface. To log in, he will need to enter his username and password. By default, both of these fields require the word root.
Externally, the Antminer S9 web interface has certain similarities with previous models from BITMAIN, but everything is even more simplified. There are no additional settings present in the S7 model. However, an experienced user will be able to perform all the necessary settings using an SSH connection.
In the first tab called System, it is important to pay attention to the special Upgrade tab, with which the user can update the system, save the current device configuration, or restore previously saved settings. If you need to make changes to network settings or set a static IP address, you need to go to the Network tab. However, experts strongly discourage making changes unless necessary, as they may lead to the device being unavailable in the web interface. The only way to solve this problem is to reset it to factory settings using the Reset button.
Appearance and interfaces
The S9 looks similar to previous ASICs from this manufacturer: the same elongated body, ending with coolers on both sides. Thanks to this design, it is perfectly possible to “blow” heat out. On the sides of the body there are ribs for connecting several miners into a farm.
On top there is a network controller and indicator lights. There is a slot for an SD card, which will be needed to flash the miner if the need arises. Inside the device there are three boards with chips, all of them are equipped with radiators covering each chip on both sides. Cooling is a sore point for this model: the manufacturer was forced to slightly reduce the frequency of the processors, and therefore the hashrate, due to the fact that the device overheated, but the fans were installed even too powerful, and the problem was that they were not operating efficiently enough. Moreover, they make a lot of noise, and therefore, if the room is not hot, their rotation speed can be reduced to 60-70% of the default setting.
The S9 is configured and managed using the web interface from Bitmain, which is famous for its convenience and breadth of capabilities: thanks to the competent interface, managing the device is very simple. You will be provided with all the information about temperature, hash rate and other important aspects of the ASIC operation, you can get both information at the time of the request and a statistical summary for comparison. In addition to the web interface, the device’s status can be monitored using a smartphone by installing an application from the manufacturer on it.
Setting up a device for mining
How does the first connection to antminer S9 occur?
- Install the miner so that there is nothing obstructing the cooling fans.
- Check for damage to the housing and any unusual sounds when turning over. Due to the cooling radiator peeling off, a short circuit is possible when turned on; this can be easily avoided by making a preliminary diagnosis.
- The power supply must be connected in series to each Pin connector . If you connect 2 power supplies at once to increase the power reserve during overclocking and achieve the maximum value of the antminer S9 th/s, check whether the connectors of both power supplies are connected to the connectors of one board.
The green Normal indicator blinking indicates that the antminer S9 connection was successful. If the red Fault signal turns on at startup, wait (2-5 minutes) until the device returns to normal mode.
Further configuration of antminer S9 begins with determining the network address. Connect the ASIC to the Internet and check the DHCP client lists in your router interface, or use the IP Reporter application.
- Install and launch the application and press the Start button on the display.
- Press and hold the IP report button on the antminer S9 control panel for 5-6 seconds.
- After the program determines the IP and MAC address of the device, enter the IP in the address bar of the browser and enter the username and password ( root – root ) to go to the miner interface.
- Open the GeneralConfiguration tab and enter the data of the selected pool in the antminer s9 settings.
If the connection is correct and the standard settings are saved, the miner will begin mining cryptocurrency automatically on the BITMAIN pool. In this case, the user’s first priority is to configure the ASIC S9 for the pool or register on the pool itself if these actions have not been performed by him previously. Miners from BITMAIN use a custom modification of the protocol called startum. In this regard, full-fledged cryptocurrency mining is possible only on Chinese pools such as F2pool and Antpool.
To create an account on bitmain antpool, you must:
- go to the registration page;
- enter your email, password and captcha;
- agree to the rules and click create an account;
- enter the phone number;
- we receive an SMS code;
- Confirm your account and log in to the pool.
You must create your own USER ID instead of "antminer". It is not necessary to change the miner's name and antminer s9 password in the worker section, they were created automatically. To stop mining if the temperature of the antminer S9 is close to the critical point, check the “Stoprunningwhentemperatureisover 80” box. This way you will avoid overheating of the device during the hot season.
You can control the antminer S9 temperature and noise by adjusting the speed of the coolers. In the “AdvancedSettings” section you can adjust the clock frequency of the device chips. Using this option you can slow down or speed up mining of antminer S9. Do not exceed permissible frequency variation limits. The parameters for each batch are listed on the Bitmain website.
After the start, in the “MinerStatus” section, you need to check the antminer S9 mining statistics. Don't expect the data to appear instantly, it takes some time. If there are no statistics for a long time, reboot the miner and contact support.
In order to change the mining pool on antminer S9, you must:
- stop mining by pressing reset;
- log into the ASIC configurator using the network address;
- replace the data of the first pool;
For example, to configure antminer s9 nicehash:
- In the URL field enter stratum+tcp://sha256.eu.nicehash.com
- Worker wallet address NiceHash
- Password x
Click “Save” and reboot. If the pool replacement fails, you need to flash antminer S9.
Also, as an example, consider the registration process on Antpool. It will not require much effort from the user, since the interface of the official portal has been partially translated into Russian. During the first login, you will need to create a personal account, which will later be used for cryptocurrency mining (in this regard, it is recommended to save it).
To subsequently configure the device for a specific account, nothing else is needed. After registering an account, you need to visit the Antminer S9 web interface and replace the word antminer with the name of the created account. In this case, the worker name specified after the underscore, as well as the password, do not need to be replaced, since the latter are generated automatically.
It is recommended to leave the restriction regarding stopping the operation of the device when the temperature rises above 80 degrees. Despite the fact that the chips themselves can heat up to 100 degrees or more, experts do not recommend experimenting. The ideal operating temperature for chips should not exceed 80 degrees, and for boards - 50.
The user can also independently set the following parameters in Antminer S9:
- Fan speed.
It is recommended to install provided that the room temperature does not change. - Clock speed of the chips.
It is recommended to set it at 600 MHz for weaker models and 650 MHz for models with a performance of 14 TH/s.
Comparison of Antminer S9 and Antminer S9i models
The Antminer S9 miner was recently the flagship product of Bitmain, until it was replaced by the new Antminer S9i model. The crypto miner is a new generation of Bitcoin mining devices based on a 16nm chip.
We tested all versions of the S9 and S9i models. Are there any significant differences or is this just a well-thought-out marketing ploy by Bitmain? Read our review.
Dimensions
Bitmain Antminer S9 miners weigh 5.5 kg. The S9i models are 1.3 kg lighter, their weight is only 4.2, which significantly affects compactness, mobility and conditions for transportation and placement. When purchasing one or two miners, the difference is not great, but with large delivery volumes, the weight will have to be taken into account.
Moreover, the dimensions of all models are the same: 35 x 13.5 x 15.8 cm (length, width and height, respectively).
Price
The price of devices including power supply differs slightly. Antminer S9i 13 TH/s costs $780, S9i 13.5 TH/s model sells for $808, S9i 14 TH/s – $837.
However, Antminer S9 can only be found through distributors; since May 2020, these models have not been provided on the website. Prices from distributors may differ from those stated on the Bitmain website.
Noise
The S9i ASIC miner does not make excessive noise when operating. The maximum noise level is -76 dB.
In the case of the S9, fans already at 30% speed create noise of up to 75 dB, which does not allow you to stay nearby or even in the next room for a long time without additional sound insulation.
The significant difference in noise insulation of the S9i is explained by the fact that the developers paid attention to improving the fans and this makes working with the device more comfortable.
Cooling
Bitmain has improved the S9i to ensure it runs cooler than any other Bitcoin miner. Each chip is equipped with special heatsinks made of high-quality aluminum. Two high-speed computer-controlled fans ensure timely cooling.
Energy consumption
| Model | Actual consumption W /hour | Model | Actual consumption W /hour |
| Antminer S9 13 TH/s | 1326 | Antminer S9i 13 TH/s | 1272 |
| Antminer S9 13.5 TH/s | 1324 | Antminer S9i 13.5 TH/s | 1304 |
| Antminer S9 14 TH/s | 1369 | Antminer S9i 14 TH/s | 1265 |
Conclusion comparing S9 and S9i
- Antminer S9 13 and Antminer S9i 13: The S9i model consumes an average of 54 W less.
- Antminer S9 13.5 vs Antminer S9i 13.5: both models consume almost the same amount of watts.
- Antminer S9 14 vs Antminer S9i 14: S9i 14 consumes 131 W less.
Based on the results of our comparative analysis, the most cost-effective is Antminer S9i 14 TH/s. In our opinion, compared to all models from the provided versions, this device is characterized by high performance and consumes less electricity. It is these advantages that distinguish this model from its analogues.
Improved ventilation, faster return on investment due to high energy efficiency and performance, and small dimensions for easy and convenient transportation are the main advantages of this device.
Delivery and receipt
But enough theory - let's get back to our ASIC. For me, this story began the previous week, when the EMS courier called and said that he had a package for me from China, which he delivered a few minutes later. Parcels from distant China often arrive in dented and even torn boxes, but this time the box and its contents were received safe and sound. By the way, the parcel took a relatively short time to travel: on May 31 it was delivered in China, and by the evening of June 5 I was already holding it in my hands in St. Petersburg.
The delivery turned out to be quite ascetic: the bag glued to the box contained only a delivery note from EMS and an invoice from BITMAIN, and inside the box was the Antminer S9 in person and in splendid isolation. Severe miners are not entitled to any documentation, cables or other extras. Therefore, unpacking and initial inspection went quite quickly.
The power supply, which was sent as a separate parcel, was somewhat delayed and was less fortunate - the box turned out to be crumpled, about which EMS even drew up a corresponding report. However, the block itself was not damaged.
