Antminer S9 Review – Things You Must Know Before Buying


This post was most recently updated on December 5th, 2018

With the growing difficulty to mine Bitcoins, it gets exponentially hard to really make a benefit from Bitcoin mining. Anyway, in the relatively recent past, the most ground-breaking and effective mineworker to date was presented – The Antminer s9. The Antminer s9 is the only miner that makes some decent degree of positive ROI in the present condition. Numerous reviews adulate the item while others have their questions. So I gathered here the majority of the advantages and disadvantages into one straightforward review.

6 things you have to know before purchasing an Antminer s9

  • The Antminer s9 the fastest miner accessible available

The Antminer s9 has a hash rate of 12.93TH/s – + 7% (and not 14 TH/s as promoted at times), which implies that it can produce around 0.05 Bitcoins every month. This is obviously just income and not considering the power, mining pool charges, or equipment costs. I ran the numbers against 3 distinctive Bitcoin mining adding machines and they all demonstrate a similar outcome. Around $330 a month of pure income (at the present conversion scale this equivalents around 0.05 BTC).

The Antminer S9 is additionally the most effective miner available. This implies it consumes minimal energy, less than every other miner out there. In the event that you include into account power cost also you will produce somewhat less than that – around 0.033BTC.

  • The Antminer s9 is the most costly miner available

The cost of the Antmier s9 fluctuates a lot. On Bitmain’s site you can get it for $2400. On Amazon you can buy it for $2700 and on eBay you can get it for $2000 (most likely the best place to look). This is the most costly miner available today since its predominant mining capacities. To equal the initial investment with your venture you should mine for around 10 months considering a normal power cost of $0.1/KW.
10 months is quite a while in the Bitcoin universe and a considerable measure can change – mining difficulty can rise, exchange rate will vary and these make it difficult to anticipate to what extent will it really take to equal the initial investment in this speculation.

  • You require an extra PSU to run the Antminer s9

The Antminer s9 can’t simply be connected to the outlet, it needs a PSU (power supply unit). So at whatever point you buy an Antminer remember that you should spend an extra $150 on a PSU. Bitmain (Antminer’s maker) prescribes utilizing APW3-12-1600-B2 which can be found on their site, on Amazon or on eBay at various prices too. Here’s the manner to set the miner up with the power supply (see how noisy the mineworker gets once you work it):

If you possess a PSU of an old Bitcoin miner you may utilize that too. For instance, the EVGA SuperNOVA 1300 Watt GPU PSU ought to work with this miner. If you don’t have a suitable PSU it will be best to simply purchase the APW3-12-1600-B2 and add it to your underlying investment cost. It likely won’t cost too much more than some other old PSU .

  • You might need to consider getting a cluster of S7s rather than one Antminer S9

Seeing as many people will most likely race to buy the new Antminer s9 you might need to consider getting the more old model (Antminer s7) at a lower price due of lower request. The Antminer S7 has around 33% of the hashing intensity of the s9 (it keeps running at 4.73 TH/s) however in the event that you purchase 3 utilized ones it will most likely cost less. This is what experienced miner had to say in regards to the Antminer s9: My general rating is a 3.5 since these don’t merit a 4. These are incredible miners that can replace 3 s7s. In any case, the miners gets much excessively hot over the s7s. I can undoubtedly run my 5 s7s in my carport at 55% (which I need to, that any higher and they make a very loud noise) while these are kept at 100% and still get excessively hot. I can without much of a stretch keep these at 100% with no loud noise issue and are more tranquil than the s7. If you would like to utilize the s9 then they should be in a vastly improved controlled environment to keep these enduring longer. In the event that you do go down this way however it’s essential to recalculate benefit as the Antminer s7 is less power proficient than the s9.

  • Not all Antminer s9 are made equal

Bitmain conveys their Bitcoin diggers in bunches. Each clump is not the same as the other and furthermore has an alternate hash rate. So it’s to a great degree conceivable that you’ll end up purchasing an Antminer s9 that has a hash rate of just 11.85 TH/s and not 12.93 TH/s. That is the reason it’s essential to know the details of the correct miner you’re looking for before getting it. For instance, the present batch of Antminer s9s accessible from Bitmain are just 11.85TH/s, the more faster models are already sold out. Remember that the 11.85TH/s models are priced lower than the more powerful models, so you’re not getting ripped off by buying that model. Make sure to know the exact details of the miner you are getting. This way you will be able to figure out the correct ROI and when you will earn back the original investment.

  • You get a 90 day guarantee on your mineworker (if purchased from Bitmain)

Bitmain supply their clients with a 90 day guarantee, anyway that guarantee has limitations. For instance, the guarantee won’t be legitimate if you overclock the miner (running it at a higher speed than it was intended to run). Likewise, in the event that you utilize an improper power supply or physical damage to your miner you won’t be qualified for a guarantee (e.g. lightning strike, consumption because of wet condition). Some eBay vendors will likewise supply you with a guarantee to make a sure to read carefully all the details.

Bottom line– is the Antminer s9 worth the price, despite all the trouble? In case you’re interested in getting into Bitcoin mining then the Antminer s9 is most likely the main consistent arrangement. Anyway the response to the inquiry “is the Antminer s9 worth it, despite all the trouble?” is absolutely individual. It relies upon numerous components, for example, How much cash you have access to spend on Bitcoin mining Where you live (i.e. power costs, cooling costs) How much do you trust Bitcoin’s price will ascend later on. Also, there’s the topic of the growing difficulty and how much time will go until the Antminer s9 becomes non-profitable (usually this occurs inside 8 a year). If you have more inquiries concerning the Antminer you can simply enroll the assistance of different Bitcoiners on the official thread on Bitcointalk.
