How To Repair Antminer S9

With the always increasing difficulty to mine Bitcoins information technology gets harder and harder to actually make a turn a profit every bit a Bitcoin miner. However non besides long ago the most powerful and efficient miner to date was introduced – The Antminer s9.

The Antminer s9 seems to exist to only Bitcoin miner still able to create a somewhat positive ROI in today'south surroundings. Many reviews praise the product while others have their doubts. So I decided to sum upwardly all of the pros and cons into 1 simple review – here it is earlier y'all…

6 things you need to know earlier buying an Antminer s9

1. The Antminer s9 the nigh powerful miner available on the market

The Antminer s9 has a hash rate of 12.93TH/s -+ 7% (and not 14 TH/s every bit advertised sometimes), which means that it tin generate around 0.5 Bitcoins every month. This is of form only revenue and not taking into account the electricity, mining pool fees, or hardware expenses. I ran the numbers against 3 different Bitcoin mining calculators and they all show the same upshot. Around $330 a calendar month of pure revenue (at today'southward substitution charge per unit this equals around 0.5 BTC).

The Antminer S9 is also the near efficient miner on the market. This means that it wastes the to the lowest degree amount of energy than all other miners out there. If you add into account electricity toll also you will generate a piffling less than that – effectually 0.33BTC.

2. The Antminer s9 is the near expensive miner on the market

The price of the Antmier s9 varies a lot. On Bitmain's site you can buy it for $2400 or at a similar price on Coinminer. On Amazon you can find information technology for as piffling every bit $2700 and on eBay you lot can get it for as little as $2000 (so that's probably the best identify to look).

This is the about expensive miner on the market today because its superior mining abilities. In club to suspension even with your investment you volition need to mine for well-nigh 10 month taking into account an average electricity cost of $0.ane/KW. x months is a long time in the Bitcoin universe and a lot tin alter – mining difficulty can rise, exchange rate will fluctuate and all of these make it hard to predict how long volition information technology actually accept to interruption even in this investment.

iii. Yous need an additional PSU to run the Antminer s9

The Antminer s9 can't just be plugged into the wall, it needs a PSU (power supply unit). And then whenever yous purchase an Antminer keep in mind that you will demand to spend and additional $150 on a PSU. Bitmain (Antminer'south manufacturer) recommends using APW3-12-1600-B2which can be found on their website, on Amazon or on eBay at different price points as well.

Here'due south how to set the miner up with the ability supply (notice how loud the miner gets once yous operate information technology):

If y'all ain a PSU of an old Bitcoin miner you might exist able to use that likewise. For example the EVGA SuperNOVA 1300 Watt GPU PSU should also work with this miner. However if you don't already ain a compatible PSU it will probably be all-time to just buy the APW3-12-1600-B2 and add it to your initial investment toll. It probably won't cost much more than any other old PSU you can find.

4. Y'all may desire to consider getting a bunch of S7s instead of one Antminer S9

Seeing as most people will probably rush to buy the new Antminer s9 yous may want to consider getting the older model (Antminer s7) at a discounted price due to lower demand. The Antminer S7 has about 33% of the hashing ability of the s9 (it runs at 4.73 TH/s) simply if y'all buy 3 used ones information technology volition probably toll less. Here'south what one experienced miner had to say about the Antminer s9:

My overall rating is a 3.5 since these don't deserve a iv. These are great miners that tin supplant almost three s7s. Even so, the miner gets way also hot over the s7s. I can easily run my 5 s7s in my garage in florida at 55% (which I have to because any higher and they make a loud whinny noise) while these are kept at 100% and still get too hot. I tin can easily keep these at 100% with no whinny noise upshot and are more tranquillity than the s7. If you do want to employ the s9s so they volition accept to be in a much better controlled surround(which I will accept to come up with) if you lot want to keep these lasting longer.

If y'all do get down this path though it'south important to recalculate profitability as the Antminer s7 is less ability efficient than the s9. Here's a complete comparison of the Bitcoin mining hardware bachelor.

five. Not all Antminer s9s are created equal

Bitmain delivers their Bitcoin miners in batches. Every batch is different than the other and as well has a different hash charge per unit. So it'southward extremely possible that y'all'll find yourself buying an Antminer s9 that has a hash rate of only 11.85 TH/south and non 12.93 Thursday/s. That's why it'southward of import to know the specifications of the exact miner you're looking into before buying it.

For instance, the current batch of Antminer s9s available from Bitmain are only 11.85TH/s, the more than powerful models are sold out. Withal, on eBay you lot can notwithstanding discover people selling the older more than powerful model. Keep in heed that the xi.85TH/south models are also priced lower than their bigger blood brother, and so it'southward not similar yous're getting ripped off or anything past buying that model.

Bottom line – make sure to know the EXACT specifications of the miner you lot're buying. This way you volition know to calculate the exact ROI and when you lot will interruption fifty-fifty.

half dozen. You get a xc day warranty on your miner (if bought from Bitmain)

Bitmain supply their customers with a xc day warranty, however that warranty comes with limitations. For example, the warranty won't be valid if you overclock the miner (running it at a higher speed than it was designed to run). Also, if you use an inappropriate power supply or generate environmental damage to your miner you won't be eligible for a warranty (e.g. lightning strike, corrosion due to moisture surroundings). Some eBay sellers will also supply you lot with a warranty so make certain to read the details on each listing careful.

Bottom line – is the Antminer s9 worth it?

If you're interested in getting into Bitcoin mining then the Antminer s9 is probably the only logical solution. However the answer to the question "is the Antminer s9 worth it?" is totally personal. It depends on many factors such as:

How much money you have available to spend on Bitcoin mining
Where you live (i.e. electricity costs, cooling costs)
How much exercise you believe Bitcoin's value volition ascension in the future

Also there'southward always the question of the increasing difficulty and how much time will pass until the Antminer s9 becomes obsolete (usually this happens within viii-12 months). If you have more questions about the Antminer you can e'er enlist the assist of other Bitcoiners on the official thread on Bitcointalk. Happy mining!
