this means to steal, do not treat their customers well who buy more products from bitmain.

Unfortunately we all know that money is shit, is people uccede for money and commits horrible things, money is the meanest thing is disgusting that may exist

You can't cancel the transaction just because the price of BTC/USD went down. That's how trading works.

You can't cancel a trade after you made it and lost money.

The price is fixed in bitcoins, and your wire transfer cost based based on the immediate exchange rate.

what did you expect to happen if the bitcoin price rose? them demand more money?

I am wondering, are there still AntMiner S7 coupon circulating or being handed out by Bitmains for the previous batch misshaps? Or are they all expired by now, as the base price of the S7 itself has been dropping?

They still have not HONORED any promises they made to the people who bought Batch 1 units and are IGNORING tickets about that for months now.

Just so everyone still knows.

They owe me about .5 btc for my batch one and batch two gear.

All I have asked for was a few coupons for future purchases.

No coupons not one.  I have purchased  6 since the first 3.  A few coupons for 100 each would have me squared away. But they have not done this as of yet.

Basically as George would say "They got Hand" .

 As long as they have hand they will not be very good at reimbursing people.  Even though they announced they would do so .

I purchased 6 s-7's since the Batch 1 and 2.  I am not the only waiting for something from those batches.
As I type I wonder if I will buy a batch 9 on Monday the 28th. I may and without the coupons that they really should have sent me.

Lets face it will the world boycott them? Until they pay for batch 1 and 2  the answer is no.

It is simply a lack of honor on their part.

As I await my 4 from them this monday some would say I should not speak until I get my 4.  Does not matter as I said I will most likely order more once these arrive.

yeah I got hozed on a few Batch1s and a few Batch 6(I think. forgot now). No answers to tickets, they promised me and everyone the reimbursement, coupons, etc.. Nothing. Not even a reply to the tickets about that to me and a few people I know.

Even if they know they have the best product(well.. I wouldn't say best. QL is in the SHTTER at bitmain)if they had ANY business scruples they'd not treat their customers that pretty much are dumb enough to pre-pay for their products and a lot of you people don't even complain when they send you used parts (but that's another story).

I too would have been happy with a few tickets, as I'm out about 0.8BTC total or a so.

Shame really.

I have a friend that actually overpaid and has money in his account at BITMAIN, he can log in and see it, but they have been ignoring his tickets to get the BTC sent back to him for 2 months now. What sort of BS is that??

For those people needing a way to add an additional PCIe power cable, this might do the trick and is probably better than the PCIe splitter most are familiar with if you have an available CPU power port/cable on the PS.  EPS to PCIe power adapter.

it is 18 gauge so it should work.  I think you may want to check the pcie with a meter for polarity  and if it is good.  use it on the controller as that uses the least power.

I got a coupon when I had paid my batch 9 miner and price was adjusted down and they had not shipped it yet.
Coupon was valid until 31.12.2015.
I used the coupon but I'm not very happy with that order, I waited many days for BM to adjust the exchange rate of USD which was many days behind actual. I didn't want to get miner after New Year and pulled the trigger few hours later rate of USD was changed.
Mining is more gambling than business.

Anyone have a coupon they wanna part with?

[Darthswan]

how are coupons being given out?  If I had one, i might pick up some more machines.  Are they giving them to people who already bought them?

They were given out for issues compensation, but i have not seen any for sale for a while. The price a S7 would be with a coupon make it attractive right now, but i can't find one, so i guess i can also wait 2 weeks for the price to drop 100-200$ again.

I believe $150 off coupons were issued to early B8 buyers because off price drop.

Im always very cautious around 18awg since its not always 'ideal' quality.  Good 18awg wire could probably handle 140W-180W on that connector. Less with he sheathed wire (reduced airflow).

which is why pointing it to the controller is the best way to use it. (controller should be under 75 watts at all times)

using it on a pcie that goes to a blade is a little risky (ie builder lies and uses 20 or 22 Awg not 18 awg)

People always say that, and it is good to be conservative, but on S7 each connector is just 150w max usage per connector.
I usually use 18 gauge PCIE extenders, but one time could not get them in time, so had to go to microcenter and the only connectors there were Athena, which are 20 gauge. As a result, I used them temporarily on a lower power batch (1160w, so ~120w/connector) and even that was fine, the wires were not hot and connectors were not hot either, max temp ~42C with a lazer probe. I wouldn't use that on a higher power units, but theoretically you can, see below.

wire capacity guide shows that 20 gauge wire can handle 8AX12V=96W 7.5Ax12V=90W PER WIRE and there are TWO carrying wires in PCIE connector, so even 20 gauge PCIE can handle 192W 180W max in total. Since 120 (lower batch)-150 (higher power batch) is less than 192W, i don't see much of a danger, unless this guide is wrong:

^that page says 20A for 16awg/12V (or 60A for a 6-wire PCIE connector, ~720A) which is just totally insane.

I sell quality 16awg cables and they start to be warm at >250W. at >300W they need airflow to keep for getting too hot. I haven't tried them past 320W, but I imagine they would become concerningly hot and/or begin to fail at >350W

Anecdotal evidence across these forums show that cable fires and failures in 18awg psus are common when loading >200W, and that 16awg generally does not push past 300W gracefully (such as for KnC devices)

I think that only two yellow (maybe three-PCIE wiki description is weird) lines carry the current, not six (black wires are ground), so 2X20=40A for 16awg, so theoretical 480W (wasn't that what KNC did?)

I disagree about common failure of 18awg at >200. The Corsair CX 750 has just two double headed PCIe cables, no more than 18awg.
I am not aware of any consistent failures of this PSU cables when running S5, which was ~600W, so ~300W/cable and ~150W/head.
To my knowledge, people run this miner for months in this configuration. Yes, cable got somewhat warm, but did not exceed ~45C.
Optimally, cables were getting (should be getting) some airflow.

That said, more the better, i will not argue this, and quality is paramount, of course.

I threw this old psu cable on an s5 about 2 months ago and will never use any small or cheap cables again.  I had a couple of S5's that I thought I would just throw online with a couple of leftover PSU'S and damn near started a fire.

sorry, but this does not even look like 6-prong PCIE connector (it got eight wires coming in). What is that plastic thing to the left? It would have prevented good contacts if it supposed to be a 6 pin. If it is the part (8 pin) connecting to PSU, OK, if it was connected to the proper place on the PSU.
One possibility is that you connected a 8 pin connector to six pins in the receptacle, since i see three burned off pins and a fourth that is still there (not burned).
Is this possible?

That said, a good example of potential dangers, thanks.

I would advise completely ignoring that Site, it may contain some correct information, however a lot of it is either misguided, misleading or just plain wrong...
