1. Antminer S9 (best bitcoin mining hardware 2018)


  • Weight – 10.36 pounds (4.69 kg)
  • Size – 17.3 x 8.3 x 9.8 inches (43.94 x 21.08 x 24.89 cm)
  • Hash Power – 14 TH/s
  • Power Consumption – 1372W
  • Our Rating: (4.8 / 5)

Antminer S9 is the number one mining hardware that I recommend if you can spend a considerable amount of money and if you need to make bitcoin on a large scale. The significant thing about this miner is that it does not need a separate host computer or any software (Built-in web management portal) to run. You may get these questions.

Then how does it mine?
How can we connect it to the internet?

Yes, Antminer S9 can mine on its own and you don’t need to connect it to a PC. You have to join the Antminer to the internet with an Ethernet jack on the machine.

After joining, you have to check the network and find the IP address of the miner, and then you can configure it.

Although it is a top-level miner setup and configuration is so easy. In good bitcoin mining hardware, won’t see any of the frayed wires or any internal part sticking out. We can see that characteristic also in Antminer S9.


From the machines that I have reviewed, this miner can bring you the highest profit. Although the power consumption is somewhat higher than others, it has a hash power of 14TH/s (TeraHash per second).

If you can use solar panels for electricity, you can obtain the amount that you spent to buy this miner before six months. There is a facility to adjust three pool options too. You can use blockchain information about pools before you configure it.


Temperature Maintenance

It consumes more power and heats up very fast. It should keep in an open area without being covered by anything. The reason is the machine outputs 255 Cubic Feet (ft³) of air in every minute.

Not necessary of using portable air-cooling systems, it already has cooling fans inside it.


It is equal to the sound of a regular vacuum cleaner (noise is somewhat larger than other miners). The best place to keep the Antminer S9 is your garage or a separate room. Remember to open windows or provide a way to flow the hot air.

Power Supply and Efficiency

You have to buy the power supply separately. It needs a power supply that can give 1800W power. I Recommend AntMiner S9 L3+ Power Supply.

Efficiency level is entirely on a top level than other mining machines.

Setup and Configuration

It is very easy to setup because you don’t need to connect it to a computer. Unpack the package and connect with power supply. Then connect it to the internet with Ethernet jack.

You can configure the Antminer S9 settings easily by accessing the IP address of the device. All guidelines are included in the official Antminer S9 installation guide.

If you are thinking to make bitcoin on a large scale, Antminer S9 must be your choice.


  • Efficiency is high
  • Setup is effortless
  • No need for additional software
  • High Hash power


  • Make a big noise
  • Consumes a higher amount of electricity
  • Releases a large heat


2. Antminer T9 (best bitcoin miner 2017)


  • Weight – 9.99 pounds (4.53 kg)
  • Size – 13.8 x 6.2 x 5.3 inches (35.05 x 15.74 x 13.46 cm)
  • Hash Power – 11.5TH/s
  • Power Consumption – 1372W
  • Our Rating: (4.7 / 5)

When comparing with Antminer S9, Antminer T9 is somewhat less potent than the S9 model. T9 version came after S9 version, and it made to reduce the errors found on the S9 miner.

The chipset of T9 is advance than S9 version. There was a small error in pre-auto-frequency in S9 version. It has been removed in Antminer T9. But it is not very famous like the S9 model.

Although it is on our best bitcoin mining hardware list and is hardly found in any marketplace. It also does not need any separate host computer required for operation (same as the S9 version).


Profitability is somewhat lower than S9 miner because the hash power is about 11.5 TH/s. Power consumption is higher than an S9 model. Antminer T9 consumes about 1450W, and Antminer S9 consumes about 1372W. Hash rate is 11.5: 14

We can decide that If Antminer T9 has a hash power of 14 TH/s, it will absorb around 1765W.

When considering with the S9, T9 is more stable. After some months, profitability will not decrease (without considering mining difficulty)


Temperature Maintenance

When considered the previous model, temperatures of the chips are significantly low because of the stability. Need to provide an excellent way to flow air in and out of the machine.

Protect the mining machine from dust and clean thoroughly once a week to maintain good efficiency.


Although it is on the 2nd place of the best bitcoin miner hardware list, the noise level is high (Sound like a vacuum) and somewhat lower than the noise of Antminer S9. Garage a separate room can be used to keep the miner, or you can use an apparatus like this.

Power Supply and Efficiency

You have to buy the power supply separately for this too. This needs a very stable power supply that can give 1600W of power.

It works with APW3 or APW5 power supplies. Therefore I Recommend buying AntMiner APW3 Power Supply. Efficiency level is lower than S9 and higher than all the other miners.

Setup and Configuration

Setup and configuration are same as S9. If you need further information, read this Antminer official guide.

When Comparing Antminer S9 and Antminer T9, these are the Pros and Cons of Antminer T9


  • Much more Reliable than Antminer S9
  • Setup is straightforward
  • Efficiency is high


  • Make big noises
  • Consumes a higher amount of electricity
  • Hash power is lower than S9
  • Less potent than most S9s

If you need to make bitcoin on a large scale, this must be your 2nd choice in addition to Antminer S9 versions available.


3. Avalon 741


  • Weight – 10.58 pounds (4.79 kg)
  • Size -12.6 x 5.3 x 5.9 inches (32 x 13.46 x 14.98 cm)
  • Hash Power – 7.3 TH/s
  • Power Consumption – 1150W
  • Our Rating: (4.6 / 5)

Avalon 741 is an improved version of Avalon Miner 721 and manufactured by Canaan Creative. Avalon 741 boasts a better ventilation system. There is no built-in controller, and you have to use a separate controller to work. It comes with a metallic box and has only one fan.

There is a weird shape of heatsinks and you can see that when you look through fan grid. It uses Airforming Cooling technology to reduce heat through heatsinks. The significant thing about Avalon 741 miner is if you have several miners you can chain them to be controlled by one Raspberry Pi.

Only SHA-256 operation optimized for BTC mining in this machine. There are several reasons for Avalon 741 to be the 3rd place on our best bitcoin mining hardware list. Let’s see what they are.


You can obtain a mid-range profit by this machine. Avalon 741 is better regarding durability as well as price. Antminer S9 and T9 are better concerning electricity consumption and hash power.

It is profitable as you can return on investment within 5 to 6 months.


Temperature Maintenance

Avalon 741 has high-temperature protection function. It does not get heated like Antminer S9 and you can monitor the temperature of the miner in the network.

As there is a considerable amount of heat, it is better to place the machine in an open area which is open to air. (Additional cooling systems are not necessary because it has an Airform cooling technology for decreasing temperature) This is the official temperature test by

temperature monitor avalon 741


According to Canaan, it is about 50-60db. If you need more information about noise check this screenshot. He is an Amazon buyer who purchased the miner. Avalon 741 has 7+ TH/s hash power and doesn’t make loud noises.


Power Supply and Efficiency

You have to buy the power supply separately as well. We highly recommend the same AntMiner S9 L3+ power supply for this also as it needs a stable power of 1293W. Efficiency is lower than Avalon 741, Antminer S9 and Antminer T9.

Setup and configuration

Setup process contains four basic steps.

1) Connect your Computer to Internet cable and connect the machine to the Avalon Miner controller. After that connect the controller to PC with wires. Default Avalon miner IP address is

2) After changing your computer IP address into, you have access to controller website.

3)Then you can configure pool information and other things.

If you are unable to configure, please check the official setup and installation manual and the official installation video for more information.


  • Made with reliable open quality
  • Best for small home miners
  • Efficiency is about 0.16 Joules
  • Use of Airforming Cooling technology


  • Need a separate controller to connect to a computer. I recommend Blokforge separate controller.
  • Not suitable to place in a living room (Need a separate room)
  • Less potent than Antminer S9 and T9


4. Antminer S7


  • Weight – 7.5 pounds (3.40 kg)
  • Size -11.8 x 6.1 x 4.8 inches (29.97 x 15.49 x 12.19 cm)
  • Hash Power – 4.73 TH/s
  • Power Consumption – 1293W
  • Our Rating: (4.6 / 5)

Antminer S9 and T9 versions released in 2016. Antminer S7 released in 2015 and it has a low hash rate than Antminer S9 and T9. It’s now reached its 20+th batch of production.

It became very popular in 2015 due to the low power consumption than S5 version. After the arrival of Antminer S9, this became less popular.

The price is very reasonable when compared with Antminer S5. You need a high-end computer PSU to connect to it. There is a separate power supply to control board, and one additional 6pin PCI-e connector must be connected to the PSU to get the power. You can see that one on the IO board.

S7 miner doesn’t come with a power supply and I recommend buying Antminer Power Supply APW3++.


If you can spend around $1500 for a bitcoin miner and willing to get maximum bitcoin profit, this is the best bitcoin mining hardware that you can get the maximum profitability.

It consumes some more energy when compared to Antminer T9, but still, you can get a good bitcoin profit. You will be able to earn the money that you invested in the miner before five months.

Always Keep the miner away from dust and intense sunlight. Clean thoroughly once a week to obtain a stable long-term profit.

When compared to Antminer S9, power consumption is not very low. Therefore profitability is lower than Antminer S9 and T9.


Temperature Maintenance

There is only one 12038 cooling fan. This machine needs a proper atmospheric temperature to work at its maximum efficiency (room temperature or below that level). Therefore keep the area cold and dry to extend the life of these machines. A garage or a separate room, which let’s air to ventilate easily will be a right place to keep it.


The noise level is at 25C – 34C is 61dB. As it is noisier than Avalon 741, keep in a separate room. To understand the noise level of Antminer S7, please refer this video.

Power Supply and Efficiency

I highly recommend Antminer Power Supply APW3++ for this model.

NB: APW3++ power supply is suitable for Antminer S9, Antminer T9, Antminer S7 and many more bitcoin miners. So it is good to buy an APW3++ power supply if you are going for the Antminer S7 model. If you are planning to move for a better version like S9, you won’t need another power supply.

As it consumes about 1293W power, when compared with the S9 version, efficiency is somewhat lower than Antminer S9. When comparing Antminer bitcoin machines, it is essential to know that each new version has twice more ability than previous one.

Setup and configuration

Setting up the Antminer S7 is somewhat different than others, and it is also effortless. Antminer S7 has DHCP capability. It means, they’ll automatically seek out an IP address to use. Therefore no need for connecting to new IP address like Avalon 741.

Connecting with MinerLink GUI is simple. It only asks for the prefer mining pool options that you need to start mining process.

If you need more information please refer these videos.


  • Easy to set up and configure
  • Good for a newbie
  • Efficiency is 0.25 Joules per GH/s


  • High power consumption
  • Produce a considerable noise
  • Less durability


5. Avalon 6


  • Weight – 9.48 pounds (4.3 kg)
  • Size – 13.9 x 5.1 x 5.9 inches (35.3 x 12.95 x 14.98 cm)
  • Hash Power – 3.5 TH/s
  • Power Consumption – 1200W
  • Our Rating: (4.5 / 5)

Avalon 6 is one of the best bitcoin mining hardware to make mining rigs. If you are looking for is a miner which comfortably fits in your room, won’t bother you making any disturbing noises and won’t produce much heat, Avalon 6 is the perfect Bitcoin miner hardware.

And also Avalon 6 suits for guys looking for a miner which costs around $1000. I will explain it step by step here.

Avalon 6 is the most significant and best mining hardware from Canaan Creative. This was built after the Avalon 5th version by improving the cooling system and setup method. There is a streamlined cooling system for this machine.

If you are planning to build a miner rig, this is a perfect choice. There is a particular RPI controller and software, which can control 40 to 50 miners at once. It can manage a large data center efficiently. You can connect miners next in the chain, without the need of a USB hub to control them. After that using software, you can configure all settings in every miner.

Both Avalon 4 and Avalon 6 uses RPi (Raspberry Pi) for its controller software. It has a unique control panel as well as CGminer panel.

The Avalon6 requires a minimum 1200W power supply and I suggest standard computer ATX power supply rated at 1200W for this.



Like I said before if you are planning to build a miner rig, this is more profitable than other miners.

It is difficult to tell the exact profit that you can make within a month because it depends on more factors like electricity, pool fees, mining difficulty, changes in hash rates. If Avalon 6 makes x profit for a month, if you are building a miner rig, with 10 Avalon 6 miners, definitely you can get a profit larger than 10x. You can use this calculator to calculate estimate profit.

Avalon 6 is still profitable when considering with Antminers. This is possible because of the rising price of Bitcoin. It consumes low electricity level than the previously discussed miners, and if you can optimize mining pools as well, you can get a considerable amount of profit.



Temperature Maintenance

When it comes to the temperature factor, Avalon 6 is the best of all other miners. It has excellent features in temperature. Yeah, that’s right! In this miner, you can adjust the temperature by changing the frequency. By adjusting the rate what happens is it works on underclocked mode.

This miner is designed to work below 35C temperature level. No need of adding extra fans, extra cooling systems, it has been built up to work with just one fan. It is so easy.


Avalon 6 is quiet enough to run at home. To understand the noise level of Avalon 6 miner, please refer this amazon buyer reviews.


Especially all Avalon miners are made up by specializing the temperature and noise fact. When it comes to noise and temperature, Avalon miners perform much better than all other Antminer branded bitcoin mining hardware.

This youtube video will give you an idea about the noise of the miner.

Power Supply and Efficiency

This miner needs a very stable and minimum power supply of 1200W. I recommend standard computer ATX power supply rated at 1200W for this. Efficiency is more significant than Antminer S9 because we can adjust the frequency level and can change the efficiency level and obtain different profitable levels.

Setup and configuration

These are the steps that you have to follow when connecting to a power supply

1.   Turn off PSU

2.   Connect the miner to all 4-power connector separately

3.   Powering the PSU

You can run the miner on your PC also. It doesn’t need a high-end PC. But it is somewhat complicated to mine in custom mode after installing various software. We highly recommend using only suitable configurations and setting up mining pools.

If you need to start mining in your bedroom, this is the best choice.


  • Durable
  • Has a high-efficiency level
  • No need of using additional cooling systems or sound control systems
  • Ability to adjust the temperature
  • Due to the low noise level, can start mine in the bedroom also


  • Low Hash power
  • Profitability is less


6. Antminer S5


  • Weight – 6.31 pounds (2.86 kg)
  • Size – 11.8 x 5.2 x 6.1 inches (29.97 x 13.20 x 15.49 cm)
  • Hash Power – 1155 GH/s
  • Power Consumption – 560W
  • Our Rating: (4.4 / 5)

After the arrival of Antminer S3, developers discovered that there are some minor issues in the chipset and hashing boards. When designing Antminer S5, those factors were highly considered.

It is standalone and doesn’t require any external controllers. It is lightweight than all the best Bitcoin miner hardware that I described before. Bitmain released the Antminer S5 version in late 2014. If you are going to test Bitcoin mining or you are doing it as a hobby, it is an excellent choice to buy an Antminer S5.

You can use a separate software (CGMiner, BFGMiner, EasyMiner, RPC Miner) also for mining in S5.


You can use this miner to make Bitcoin profits, but if you are willing to start mining to get massive profits, Antminer S5 is not suitable for you. Your option should be a miner like Antminer S9, Antminer T9 or Avalon 741.

Antminer S5 is still worth considering if you like to start mining as a newbie or to go to do it as a hobby.

Some people make≈0.0004 BTC for one day using Antminer S5 from Slushpool.



Temperature Maintenance

Temperature is high when considered to previously mentioned miners. After 10 hours of hard mining work, the temperature reaches 53C. However, the maintained onboard temperature should be below 80C. You can reduce the heat with portable fans and cooling systems.

You have to keep the onboard temperature below 60C. If not the miner’s lifetime will decrease rapidly.


This machine is not a good option to start the mining in the living room without noise reduction. Because it’s noise just like an industrial vacuum machine. Some guys try to decrease the noise level by replacing fans and by adding extra fans. This youtube video will give you an idea of the noise.

Power Supply and Efficiency

It is a lot more efficient than Antminer S3 version and less efficient than Antminer S7 and higher models. You can use an ATX power supply with four 6-pin PCI-e connectors. I recommend 80 PLUS BRONZE power supply rated for at least 650W Or TOUGHPOWER 750W 80 PLUS GOLD Power supply.

NB: Power supplies’ efficiency is rated as gold, silver, and bronze. Which,

⦿Gold (10% of electricity wasted)

⦿Silver (20% of electricity wasted)

⦿Bronze (30% of electricity wasted)

Setup and configuration

You don’t need to search out for available IP addresses like Antminer S9 and Antminer T9. Antmier S5 automatically searches for available IP address to use.

Configuration is also easy. You have only to adjust the pool options. If you upgrade the device’s firmware, you can share access privileges to the miner directly via the network connection. Using MinerLink software you can observe the status of your miner.


  • Low price
  • Low power consumption
  • Suitable for experimental works


  • High noise level
  • High heat release
  • Not so profitable


Final Words about Antminer S5

If you are willing to start mining in your bedroom, this is not suitable for you. This will better suits for a guy who likes to experiment about bitcoin mining and doing it as a hobby. You can use it to learn about bitcoin mining. Can do experiments to decrease the noise level, heat level and so on.


7. Antminer D3


  • Weight – 5 pounds (2.26 kg)
  • Size – 12.6 x 5.1 x 7.5 inches (32 x 12.95 x 19.05 cm)
  • Hash Power – 15 GH/s
  • Power Consumption – 1200W
  • Our Rating: (4.3 / 5)

When considering about Dash ASIC miners, Antminer D3 is the best in the category. It released in 2017 and the hashing algorithm is X11 (Dash and many others).

It mines Dash coins, not Bitcoins. Dashcoin has some significant features in common with Bitcoin.dashcoin chart 2018

When referring to this graph about Dashcoin price change, we can identify that the rate of Dashcoin is increasing rapidly. From January 1, 2017, to January 1, 2018, it has raised more than 8000% Cryptocurrency experts predict that it will increase more than 50000% within next five years.

As we all know the most famous cryptocurrency now is Bitcoin. After some years Dashcoin can become the most popular cryptocurrency because of the incensement of the value.

If you like to mine dashcoin Antminer D3 should be your first choice, and I suggest you don’t spend all dashcoins that you make from mining. Just spend some dashcoins per month to pay your electricity bill and store your remaining dashcoins in your web wallet or your hardware wallet.


It consumes about 1200W and it has only 15 GH/s hash power. It sounds like you just can’t get a 5$ profit? Yes, it can’t generate much profit like previous miners.

It has high power consumption, and there is only 15GH/s. Antminer S9 beast consumes only 1372W and outputs 14 TH/s hash power.

But Antminer D3, mines dashcoin that came into the market in 2014. Only four years passed and it still has a lot more to develop. If you are planning to make a long-term investment, this one is very suitable you.


Temperature Maintenance

Antminer D3 releases more heat and becomes unstable at 70+°C temperatures. The machine is stable at PCB temperature 60°C-69°C with chipset temperature 70°C -80°C and hardware errors become almost 0.

If the temperature becomes more than 70°C, you have to control the temperature manually by adding more fans to it.

You should provide an excellent way to release hot air from the room. Keep the windows open. Furthermore, it is better if you can place an additional fan to increase the cooling effect.


The average noise level of Antminer D3 is 80 dB – 85 dB. It’s like the sound of Food blender, milling machine, Car wash at 20 ft or diesel train at 45 mph at 100 ft. It is not suitable to be kept in your bedroom. You can arrange the garage or a separate room for mining.

Power Supply and Efficiency

Antminer D3 needs a power supply that includes ten 6-pin PCIe connectors. I recommend using Antminer APW3++ Power Supply.

When considering with previous miner machines, D3 has less efficiency than other miners. The reason is that it consumes 1200W and produces only 15 GH/s. But as I explained, in the beginning, it makes dashcoins. Although the efficiency is low, it is a good future investment.

Setup and configuration

The configuration of Antminer D3 is straightforward and setting up process is somewhat tricky.

⦿ Connect the miner with power supply by connecting all 6-pin connectors. After that connect the Ethernet cord & connect the power cable to turn on the power supply.

⦿ Within 2 minutes, the green light will begin flashing, indicating that the miner has begun to work.

⦿ Change the IP address to your browser to access the user interface.

⦿ Configure static IP, input the IP address and others as well. Then you will see miner settings on your display.

⦿ Select the miner configuration screen. Configure mining pool information.

Watch this video if you can’t understand yet.


  • Can mine Dashcoin directly
  • Low price


  • High noise level
  • High heat release
  • Less efficiency


Final Words

If you are willing to make a good future investment with Dashcoin, this is the best bitcoin mining hardware. It needs a particular area to store and need some manual tricks for reducing heat and noise.


8. Antminer L3+


  • Weight – 12 pounds (5.44 kg)
  • Size – 13.9 x 5.1 x 7.4 inches (35.30 x 12.95 x 18.79 cm)
  • Hash Power – 504 MH/s
  • Power Consumption – 800W
  • Our Rating: (4.1 / 5)

Do you feel like there is a difference in the name? Yeah, Antminer L3+ is also not a direct bitcoin miner. It directly mines, Liitecoin and an improved version of Antmier L3.

litecoin rising chart

Mining Litecoin is the main reason for adding this machine to the best bitcoin mining hardware collection. Bitmain released Antminer L3+ Litecoin miner on 31 Aug 2017. The arrival date of Antminer L3 was January 2017. After the arrival of Antminer L3, there was a vast difference in the value of Litecoin.

Developers planned to design a new machine by considering the faults of Antminer L3. Antminer L3+ has a hash power of 504 MH/s, and it consumes 800W to produce that much hash power.


It is the world’s most potent and efficient Litecoin miner yet (March 2018). When considering the power consumption and hash power, you may misunderstand that it is not worthy. But the most important fact is the mining difficulty of Litecoin. It is shallow when considering the challenge of mining Bitcoin. For that reason, it’s worth the money you spend on it.

When surfing Reddit, I recently found a post from a guy who has made $1150 per month using Antminer L3+. Consider this value if you need a numerical answer.


Temperature Maintenance

Antminer L3+ releases more heat and becomes unstable at 70+°C temperatures.

When the ambient temperature of the room is between 23-27°C, the average temperature of the PCB is about 55°C and temperature of the chipset is about 63°C. The miner will stop running when the PCB temperature is over 85°C. You have to keep the miner in a separate room or your garage and provide a better way to release the heat. It is good to use additional heat removal and noise removal methods.


The usual noise level of Antminer L3+ is 60 dB. It’s like the sound of conversation in restaurant or an office. It is not suitable to keep on your bedroom. You can use the bedroom, but you have to make portable noise cancelation techniques. In this point also I recommend arranging the garage or a separate room for mining.

Power Supply and Efficiency

Antminer Power Supply APW3++ is the best power supply for Antminer L3+ miner. This is a top efficiency level miner, which has a low hash power

Setup and configuration

It is not very complicated and same as the setup of Antminer D3. Please refer the official installation guide for more details.


  • Can mine Litecoin directly
  • High efficiency


  • High noise level
  • High heat release


Final Words

If you are willing to make a Litecoin, this is the best bitcoin mining hardware that you are looking. To get the maximum efficiency, need a particular area to store. Need some manual tricks for reducing heat and noise.


9. Antminer S3+


  • Weight – 12.96 pounds (5.87 kg)
  • Size – 13 x 6.3 x 5.4 inches (33.02 x 16 x 13.71 cm)
  • Hash Power – 453 GH/s
  • Power Consumption – 355W
  • Our Rating: (4 / 5)

Antiminer S3+ is the improved version of Antiminer S3. In the normal state, it has a hashrate of 453GH/s. But we can overclock it by some tricks and makeup to 500 GH/s. It is somewhat dangerous overclocking without having proper knowledge. Sometimes your guarantee for the product will lose after overclocking.

Antminer S3+ is standalone and mines without a server, laptop or PC. It is larger than Antminer S9 in appearance. If you are willing to make a severe bitcoin profit, this one is not suitable for you.


It is a somewhat old miner and looks bigger than Antminer S9. Price of this miner is meager when compared with Antminer S9 and Antminer T9, and power consumption is also lower than giant miners.

Although it has a hash rate of 453GH/s, it is profitable for the purchasing price. The truth is you can’t make bitcoins on a large scale using S3+. But there is a considerable amount of profit after paying electricity bill and pool fees.

NB: Keep in mind that it takes a long time to give you a considerable amount of Bitcoin profit. Buy this one if you don’t have a reasonable budget to purchase a miner like Antminer S9, Antminer T9, Avalon 741 and Antminer S7.


Temperature Maintenance

Although it is an old machine, Antminer S3+ doesn’t release more heat as we expect. The temperature level is between 30-60C, almost 45C. You can overclock the miner to get a higher hash power, but there are so many side effects after overclocking. The temperature will increase rapidly and lifetime will decrease.


It is not that bad, like a vacuum cleaner. Some guys are doing various experiments, for instance, replacing the existing fans with new versions to control the noise. But we do not recommend removing any parts from miners. Using noise cancellation and heat removal boxes is a good option.

Power Supply and Efficiency

You can run a S3+ miner with 500W if you don’t overclock it. I recommend using a 650W high-end 80 Gold or Platinum series power supply. This power supply helps in keeping the power consumption down, and it helps the miner to give a higher hashrate more stable over time.

It has a high energy efficient level to save your investment on PSU and electricity bills.

Setup and configuration

It is effortless because both S3 and S3+ is standalone and does not require an external controller. This is the official manual for Antminer S3 and S3+.


  • Low price
  • Suitable for experimental purposes


  • Low hash power
  • High heat release


10. Antminer S3


  • Weight – 12.9 pounds (5.85 kg)
  • Size – 14 x 10 x 9 inches (35.56 x 25.4 x 22.86 cm)
  • Hash Power – 441 GH/s
  • Power Consumption – 366W
  • Our Rating: (4 / 5)

It is not suitable for mining Bitcoin in 2018. If you think you need to train and practice before buying professional miner, Antminer S3 and Antminer S5 are suitable. They are the best miner hardware for learning.

This only suits for folks who need to try out new things with bitcoin mining and just for beginners who need to learn about the process.

Found a video uploaded on 2015 by a small boy who mines with Antminer S3.


Profitability is less than every bitcoin miner that I have explained above. There is a very less amount of bitcoin profit after paying the electricity bill. I have chosen this miner without considering the profitability.


Temperature Maintenance

Temperature level is very high as it is an old machine. It is almost like 50C. Try adding manual temperature controlling methods to reduce heat.


Noise is not that bad as you can keep it in your bedroom. I highly suggest you that, if you are going to buy Antminer S3, just don’t start mining after setting up. Try to stop the noise level and try to maintain the heat release by doing various experiments. You can find lots of tests on youtube.

Power Supply and Efficiency

As the power consumption is 366W, I recommend using a 650W high-end 80 Gold or Platinum series power supply. Try to overclock the Antminer S3 and see the efficiency difference if you are willing to buy it.

Setup and configuration

As I mentioned before both Antminer S3 and Antminer S3+ has the same way to setup and configure. Follow the official manual if you need any help in setup and configure.


  • Reasonable price
  • Suitable for experimental purposes


  • Low hash power
  • High heat release
  • Low power-consuming level
  • as time goes on efficiency reduces significantly
