Thanks for the reply, yeah in regretting buying that PSU now for sure.
Im also needing info on how to run the miner at home. The instructions that come with the miner say it runs on 20Amp but is only 1600w(6.5Amp). Now it says to run on two circuits at home or not to run at all. Do I need to power this using 2x PSUs plugged into different socket circuits? ( Meaning I can't use the apw PSU anyway )
Any forum users from the UK have an s9 set up at home that can confirm how you have powered it?
210=250 volt socket that can provide 8 amps will be enough for the psu i linked you to on uk eBay |

Hi All
Just noticed an S9 OFF, AP3++ was dead, no 12v Out !!!
I noticed little fan had stopped...Its starts with a 'quick flick' ...but still no output..
I'm in the UK and wondering if it is worth the cost to send for replacement to BITMAIN ??
I'm sure i seen a section where you can input serial number to check warranty ??
OR is there an internal fuse on the output i could replace myself along with small fan ??
Thanks
never never never never never buy a psu from bitmain unless you live in china. there are good psu's on uk eBay that would work. mailing or shipping it to bitmain is foolish cost = close to that of the psu. go here to read what to do https://bitcointalk.org/index.php?topic=2254568.msg22806909#msg22806909 |

Hi guys,
im new to this mining thing, my in law has a big solar farm and he wants to use his almost free electricity for mining.
i was thinking of eth maybe some other coins to split the risk.
i saw a few posts recommending the NVIDIA GTX 1050 Ti
any suggestions what i should start with at home as "proof of concept"?
i need to test out the power usage vs income and get accurate numbers before spending a large amount of money.
any help would be highly appreciated, thanks
Where do you live? If you are close to New Jersey I could build a simple machine with 1 card, you could test with it. I also would say get an asic like the Avalon 741 . |

I wanted to go into ASIC mining a couple of months ago, had a Antminer S9 in my basket and filled down my information but then I saw a video on YouTube about the noise they produce. Never thought it would be that loud, so did some tests in my study room with a device that makes an equal amount of noise and found it too loud so I canceled the order. The Avalon seems a little bit more quiet, but still too loud for the apartment I live in. The noise reducing you did seems to be going to the right direction for me. But I just hope that they will produce quieter machines in the future, so an average person can also enjoy ASIC mining.
It will certainly make your avalons quiter, but not enough to sleep in the same room. You can for example put this into your living room instead, with the idea I and philip described above. The problem is always the fan, but it is required to cool these machines down. Thus, your idea of a quiet ASIC machine is not feasible because it makes the miner much expensive, see r4 from bitmain, it has almost the hashrate as avalon but 2 or more times expensive. Water-cooled machines would make it much more expensive. My walls aren't thick enough to block most of the noise. When I watch TV in the living room I still hear it quite loud in my bedroom. I guess I got to wait till water cooling is affordable. Because water cooled mining machines like the R4 don't seem to be worth it at this moment, unless you have free electricity. The r4 was not watercooled. |

I always offer them to take a demo model and run a long thread.
After 2-3 weeks use I return it or buy it.
I really wish they would send you one to test out. Did you already contact them and did they reply or just straight up ignore you? The emails are above. To repeat less then a day of email contact and they opened presales two weeks early. Read those emails and draw your own conclusion as to why they opened preorders early. Also draw your own conclusion as to why they told me pay for the demo up front. |

anybody experienced with openwrt implementation from avalon?
I'm trying to install openvpn on the image, but no luck so far..
I tried to get a wlan stick working on my rasp for my Avalon.. Anybody know what to change to get the wlan stick working on openwrt? It is not supported. Wireless is not the way to go . |

Hello everyone, Has anyone here experimented with the immerson cooling technology from 3M? https://www.3m.com/3M/en_US/novec-us/applications/immersion-cooling/ Seems to me a very effective way of cooling and leads me to many questions: - If a is water block system can be filled with such liquid?
- Or is is available in small quantities to small miners?
Greetings Novec is the chemical it is not available on small scale. And you don't put it into a waterblock you dip your gear into a tank filled with it. the pipes carry off the heat see below  |

if you have free power.
you need a few things
a building that can extract or exhaust heat.
I would tell you to avoid eth
go for zcash
and btc + bcc
I would build nvidia rigs with the 1070 gpu
I would buy
both s-9 and avalon 741
I would source psus from sidehack here on this site.
never never never buy psu's from
bitmain or canaan.io/avalon simple reason is that psu's are easy to source right here in the USA.
I would use awesomeminer to check the asic gear
I would use smos to check the gpus.
Buysolar and I have a solar array I could possibly set your place up.
You also need good reliable internet.
I am in New Jersey what state are you in?

Sound is literally the least important aspect of miner hardware, especially to a company that would like to sell a large quantity of units. One decent sized farm places single orders most likely equal to an entire years worth of solo purchases from home users. There is no money to be made
What matters is price, efficiency, 30/60/90 day failure rates, and the ability to buy in bulk with reasonable shipping times.
Also, Syan is still saying all the wrong things if they are in fact a legit company. They offer a FIVE YEAR warranty on mining gear? How many color guard troops waving red flags does it take to clue people in?
For home-miners, noise is literally the most important aspect next to efficiency, especially to a company that specializes in serving home-miners, a market that is completely and utterly untapped into... Having said that, just tried to order more than 5 miners (as they said the limit was in this dubios press coverage) and it was no problem. Of course, I didn't go through but it might be worthwhile to notice that it's 158$ for shipping no matter how many you order, kind of strange  They did not get back to me Once again I stress : zero proof it exists 2k out of pocket jan delivery vs bitmain s-9 it exists 1.3k out of pocket nov delivery or avalon 800 well buy 2 so 1700 out of pocket nov delivery. While I am a gear junkie and I have had so many different pieces of gear. I won't risk 2k for this. I am well established here having escrowed more then 100,000 usd with zero issues I have sold more then 50,000 usd in gear here either gently used or new. My trust is really good. So I will not chase gear from new builders. I always offer them to take a demo model and run a long thread. After 2-3 weeks use I return it or buy it. Did this with pandaminer and said I like it and purchased it. Pandaminer did a lot of sales and then decided to become a really poor service company. Made a newer model that was not as good. I then withdrew my recommendation. From them. I ran a long thread on the spondoolies sp20 I ran a long thread on the avalon 4 ------- nice quiet miner. |

Hi new to the forum and haven't found any info relating to my problem so here goes
I set up my first s9 with apw PSU a few weeks ago and after around 5 minutes of running one of the capacitors on the PSU exploded and burnt out. In trying g to figure out whether this is a fault with the PSU or if somehow I have caused this.
The miner was set up at home using a heavy duty IEC cable 10a fuse 240v(UK power)
So would this have been a faulty PSU or could I have caused this? Also I've sent the power supply back to bitmain to be repaired/replaced so I have no power supply to tell wether the miner was damaged at the same time. And bitmain are slower than a week in the jail. Had the PSU for 4-5 weeks now. I would've been better off buying a new PSU the day the apw broke.
I once spent a weekend in jail it was pretty slow  Never never never never buy a psu from bitmain here is why asic miner = rare and you can not get from many sources psu = common you can buy at lots of places ebay uk http://www.ebay.co.uk/itm/High-Efficiency-2450-Watt-Power-Supply-Server-PSU-Antminer-Mining-Miner-Machine-/222669346248?http://www.ebay.co.uk/itm/1600W-Mining-Machine-Power-Supply-PSU-For-Bitcoin-Miner-S9-S7-12-5T-13T-13-5T-UK-/202054518582? |

These Delta's don't seem to like being pushed much past 1800 Watts. On my 8x 1080Ti rig, I changed power limit from 190W to 210W, and after 4 hours, it shut down. Miner went offline since I forgot to set the BIOS to power on after "power failure". Guess I'll pick up some more and run 2 on my 8+ GPU rigs after all.
As Phil pointed out, this is still way cheaper than large EVGA units, and as SCSI2 pointed out, more efficient. I'll make some custom dual C19 power cords to keep things neat.
some 1080tis go rouge and do 100% tdp When set lower. My aorus 1080 ti would often go to 300 watts. Which is its 100% tdp. It is possible you were pulling more then 2200 watts. I ran two Avalon 741 pulling 9.8 to 11 amps of 240 volts. Got hot but kept running. I now use two psus and the fans are much quieter. I prefer these to the Evga as I can get three deltas for one Evga 1600 plat |

Well you all have taught me a valuable lesson..
Indeed I should not have been so quick to boast of the simplicity and ease of electrical usage...In a public forum
Yes it is irresponsible of me to promote a set-up such as mine without listing the risks and responsibilities to diligent maintenance and supervision.
Please excuse my silly defensiveness and pride.
And yes there is huge value in the vast knowledge base of painfully gained wisdom enshrined in NEC Ashrae IEEE ASEE and many such professional orgs.
Especially with respect to PUBLIC safety and commercial operations & liability.
And yes most of these orgs very mission is to educate and advise and mature the knowledge base.
The corruption and bureaucracy and influence of commercial interests often serve to undermine and monopolize these institutions.
No amount of legislation can insulate or mitigate incompetence, negligence, corruption.
Nor can compliance alone prevent disaster..One should not be lulled into false security by compliance.
Actually physics and Eeng education and experience is absolutely essential to qualify one to DESIGN SAFE generation distribution & transmission systems.
But I agree that is no guarantee that the same individual is qualified or competent in actually building connecting servicing such.
There is many a twixt between tongue and lip.
And I did speak rather too loosely.
Thanks for the apology. |

Syan's looking doubtful but I'm glad you made an effort to see if the miner is real for all of us. Hope it's not vaporware and that they just happened to put the miner in a Cooler Master mATX/ITX case  I don't like that they now opened for preorders today 2 weeks early I live in NJ USA they want about 150 to ship and 1900 total of 2040 btc or bank transfer. Lets see if they reply back to me but I do not think you should send without at least something showing it is real. So they are a no recommendation at the moment.Zero proof and asking for 2k up front in non recoverable funds. |

Are there long-term miners on server PSUs around here ? How long has your server PSUs been lasting ? Average time before going dead ? Got early deffective ones ?
Due to their almost non-existent warranty time (30 days), I am skeptical to choose them over ATX PSUs which have 10 years warranty as I fear I might need to buy numerous ones over the span of few rigs lifetime cycles, then I am not so sure about actual savings, all things considered (reselling of ATX replacement units of never models in the long run)
delta is one of the best psu builders around. I have five so far. but I don't push them as they are low cost 130 for 1 vs 300 for an evga 1600 gold or 379 for an evga 1600 plat. |

And unfortunately they, the WSJ, CNBC and several other legit news site also readily published the Bullsh** PR's for Foxminers and others scams. Seems they just publish what the PR agencies send them and never look into the companies.
Shitty writers gotta make money somehow. Most of the writers are terribly inexperienced with crypto in general and they don't see these miners the same way we do, unfortunately. I just hope people grow brains and actually research miners before purchase, which a lot of people don't do and fall for scams like the Foxminers and other vaporware. I think they know exactly what they are doing. It gives all crypto-coins a bad name if they report a scam. Sooo fill in the dots. |

And this is most likely not a place for anyone to put money into.
If they are real you are not going to know it since they now want 2k up front for Jan 2018 delivery.
My thoughts are I don't need the gear.
I have s-9
I have Avalon 741
I have Avalon 721
I have gpus.
I have gear in the solar array.
I put in an order today they want 158 to ship and 1895. So 2053
To bad. Wish them luck

With this kind of setup perhaps putting the miner in an unused room or garage is most ideal. Basement could also work at this level of sound. The R4 is no longer in production, thankfully- it has horrible reliability and Bitmain charged an unreal markup for lower noise despite the much lower hashrate. If miner manufacturers would put the blades further apart and didn't cram so many into a small container they wouldn't be as loud, but remember their primary target is large farms that don't care about noise.
yes. The s-9 and the Avalon are design to run in a warehouse exshauting the air out And as lout as possible. Why is this. Because a small home miner with 1 or 2 or 3 units can bury them. Wtf am I talking about. Here goes any home that needs heating with decent power prices can compete with big farms. So to discourage home mining units are designed as loud as possible. Mostly to force the home miner out. My garage build allows me to run 3 Avalon and a few gpu rigs. And the noise is reduced enough to work. If you want a unit in your bedroom look at water cooled gpus. Most of my designs are designed for a home owner except for my small mining rigs. With gpus. They do not mine btc so I did not mention much about them. |

while sound may be unimportant to large farms. this company is specifically looking to bring mining back to miners in house. https://syanmining.com/but this came today http://www.abnewswire.com/pressreleases/syan-technologies-vega-bitcoin-miner-opens-for-business_150148.htmlOCTOBER 9, 2017 BY ADMIN Syan Technologies’ Vega Bitcoin Miner Opens For Business The Vega Home Bitcoin Miner from Syan Technologies went on pre-sale at 9AM on Monday 9th October, two weeks ahead of schedule. Customers can expect delivery of their new units in mid to late January, though Syan anticipates that many prospective buyers will be disappointed due to the unprecedented interest generated by the new machine. “We have just under 1200 units available to the public in this batch, and are limiting customers to 5 machines per order to try to service as many individual customers as possible; but we’ve had so much interest already I fully expect batch 1 to be sold out within the week, possibly within a couple of days,” said Koji Tanaka, Syan Technologies’ project manager and spokesperson speaking from the group’s new Hong Kong facility. “We’ve also had many requests for larger numbers of machines for farm use, but have been unable to accept their orders. I’m currently trying to pull forward the production schedules for batch 2. Quite frankly we didn’t expect such overwhelming interest so soon. We’ve done very little marketing – our new machine speaks for itself I think. We’re hoping to get our hands on the first real production model within the next few weeks and already have a number of units lined up for demonstration and review purposes. We’re all working hard here to keep everything on track, and so far we’re succeeding.” The Vega Home Bitcoin Miner is the first machine in the Vega series of currency miners, incorporating Syan’s new 14nm ASIC STA1220 chip and delivering 13.5TH/S and an efficiency ratio of 0.078 J/GHs, a good 20% better than its nearest competitor, the Bitmain Antminer S9. The retail price for the new machine is US$1,895.00 plus shipping. Syan also have a SCRYPT miner in the pipeline though no performance, release date or price details are available as yet. Syan Technologies are a Hong Kong based designer and producer of digital currency mining machines and FinTech, currently focusing on the release of their Vega Home Currency Mining series. They comprise a dedicated and highly motivated team of designers, technicians and mathematicians of diverse backgrounds – from as far afield as California, London, Sweden, Russia and Vietnam – with just one thing in common; they aim to design and produce the most cost-efficient and durable ASIC mining machines in the world.
