The more popular cryptocurrency gets by the day, the higher its value gets and the harder it becomes to mine them. This is evident with the record high 11,388,083,790 GH/s as of December 2017.
With such a massive growth, bitcoin has gone ahead to be one of the (if not the) most powerful cryptocurrency by far.
But this hasn’t shaken the resolve of the bitcoin enthusiasts out there and has even made the bitcoin and other cryptocurrencies even more popular evident with the increased investment of the altcoins mining hardware.
One such mining hardware is the Bitmain Antminer S9. It boasts of having the Nanometer Technical advantage that has convinced most miners of an increased profitability and high return on investments.
Advantages of the Bitmain Antminer S9
The Nanometer technology allows for an even greater computation power and electrical efficiency. The S9 manufacturing makes use of the 16nm fabrication process which is considered a critical enhancement on the 28nm that is used in the other mining hardware. The Bitmain BM1387 chips are made with TSMCs 16nm FinFET tech producing a record 0.098J/GHs.
The Antminer S9 Profitability
The Antminer S9 has a combined 189 chips on 3 circuit boards that goes on to produce an impressive hashing power of about 13TH/s. When calculating the profitability, things to bear in mind are the electricity cost as per your location and difficulty of the altcoin. Also during post-halving, there would be a number of miners from your mining pool that would most likely go on to either shut down or might even opt to upgrade their systems.
When mining through a pool, the fees would be divided accordingly unlike going solo where the profits are all yours if you get lucky enough to get a block. Additionally, the Altcoin to Dollar price should be kept an eye on because the cryptocurrency is never quite predictable. After all, these are put into perspective, the S9 could go on to yield about 0.285BTC/ month and about 3.36BTC/year.
On rough calculation considering all the costs, the return on Investment of the Antminer S9 turns out to be about slightly over a year.
Antminer S9 Consumption of Power
The Antminer S9 is one of the most efficient hardware out there with a consumption of about 1350 watts. When compared to its counterpart the Antminer S7 it appears to be 2.5x more efficient though uses approximately 300W more.
Recommended Power Supplies for Bitmain Antminer S9
The good news with the S9 is the availability of compatible power supplies that could feed the sufficient watts to the hardware.
- Antminer Power Supply APW3++ for S9 or L3+ or D3 w/ 10 Connectors going for $210
- AntMiner APW-12 1600 Watt Bitcoin Miner PSU going for $289
An advantage of the Antminer S9 unit is that it comes self-contained and the only thing you get additionally for the unit would have to be the power supply. It does not need a connection to another computer for interface with the Bitcoin nodes and it also has an onboard web management system that allows the setup to be simplified and the whole process maintained.
Operating temperatures of the Antminer S9
The Antminer S9 comes with a fully functioning ventilation system that is air cooled and fitted efficiently to its sturdy design. It is fitted with high-grade aluminum casing for the two fans that are computer-controlled having customized heat sinks. It makes use of both conduction and convection technologies for cooling.
The chips on the S9 have custom-made heat sinks that are made of the aluminum alloy which also makes up the S9 case.
Ease of Use
The Antminer S9 has a smoothened user interface that makes it easy to use even for beginners. It allows for easy customization of the settings before starting the mining.
Price of the Antminer S9
With a price of around $6000 the Antminer S9 may seem quite expensive but has a short Return on Investment time and could be even shorter with cheap costs of electricity. Also, things to keep in mind would have to be the difficulty and the ever-changing prices of the cryptocurrency.
To summarize, the Antminer S9 although quite costly has proven to be a good investment and as long as cryptocurrency is around, the profits are sure to be present too.
