Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

Buyer beware, I would stay away from Bitmain's gear unless you want it to look like this:

Thats why you got a burnt up miner. if there is not enough ac power at the input of the PSU you will not get enough DC output power to the miners and when this happens electrons flow through the wire really fast bouncing off atoms causing friction making the wire get hotter and hotter until meltdown like that miner you have.

Physics disagrees with you, sir.

Every time you insert and remove the plug from its socket, the internal metal contacts get looser and looser until resistance builds because of poor contact. That will then produce micro arcing ( you really wont see it at first). Thermally the connection builds up heat, melting and or starting a fire.

Older power supplies are notorious for this because the molex connections have been inserted and disconnected many times, Especially so if you use the molex connectors to shut down, turn on or reset your miners.

Invest in a non-contact thermometer and ALWAYS keep an eye on the connector temps!  If you find one that is warm, REPLACE IT!

And loose connections? Like, all of them? Lol...

It takes one loose connector. Current initially flows through the other two until they burn out and their resistance increases above that of the first loose connector. Then the loose connector starts taking the load and it quickly burns out too. It happened to me more than once with Bitfury gear.

damn, now atoms comes out. where are the aliens & flying saucers ?

B5 still stuck at clearance agency at PRC ... grrrrr

btw, i took a risk & "cleaned" my boards !

Let it dry for a day or two.

Is it hashing and would the soap and detergents corrode the board just dont keep doing it. POOF!!!!

Hi,

I made an order for two Antminer S9 B5 than I made a direct bitcoin payment but almost 72 hours after that transaction is stil unconfirmed. Bitmain said "The payment is on the way.
We don't receive it yet. " Did anybody seen something like that?

[talks_cheep]

People need to stop running their S5 and S7 miners as soon as possible, they're a fire hazard. This summer we will hear lots of stories of people's houses being burnt down because their miners burnt starting fire.

when you buy one they send an email to you so
find the tx id.  and reply in an email to them.

how to use 3 PSU EVGA 1000GQ 80+ GOLD to power 2 antminer S9
each EVGA have only 6 PCIe ( power 2 boards )
how to power the controller on both miner ?

Yet another power supply.  You need 18 PCIe just for the boards.  Note that this will likely need to be spread across 3 power circuits, unless you have 30amp 220V available.

rm1000 have 6 PCIe too and they using 3 here to power 2 miner
how they do that ?

No magic here.  You need 10 PCIe power plugs to power up the each miner.  The controller does not draw as much power and the asic boards, I suppose people are "cheating" and using a splitter on one of their plugs, but you risk overloading that plug doing so.  The combined 3000 watts of (3) 1000 watt power supplies is barely adequate as is - you will be running those supplies at max.

they use daisy chain i think

Physics disagrees with you, sir.

Okay then you explain it genius.

Are you simple?  You clearly don't understand how switched power supplies work.  Most modern power supplies can work on a range of AC input voltage from 100 to 240V, and yet they still produce a stable 12V DC output independent of AC voltage.  My server PSU's require 200+V, which I have measured 236V consistently at the plug.  Also, read my post from earlier:

As to the comment about AC wall voltage, read my case again and you will see that A) I had 9x S7's and 12x S5's hosted using the same AC power and B) that specific 4000W PSU was powering 1 other S7's and an S5, neither of which suffered from spontaneous self-combustion.

Input voltage had nothing to do with this failure, move along genius.

Edit: Seriously, look at the boards:



These boards failed from the inside out, possibly similar in failure to the Asicminer Prisma? I don't really know why, but I do know that the other miners on the same PSU and same building did not suffer the same problem.

that's a S7, this is S9 thread, let's stay on topic as much as we can but much thx for sharing.

will monitor the miners closely.

Do you really believe that this can not happen with S9 ?  I already sent one S9 B1 blade to China. Costs for me 70 euro.
Blade works maximum 2-3 hours since the arrival with lower hasheate. Fortunately, he was not burned. But I have some S7 boards with fallen off chips with radiators.

[SaBit]

it is the most advanced machine of its kind with cutting edge technology--- with Chinese "just good enough" engineering

It is bound to have a few catch fire.  ---- nothing to see here ,,, move along

It is still hands down best Bitcoin machine available at any price

okay do it your way.  i only have done it my way for 30 orders and always got credit within 24 hours.

 your way seems to make it last longer   so far 72 hours.    have fun waiting.


once again I led you to the water it is up to you to drink.
