AntMiner S3 NEWS
The Third Batch of S3 sales price is dropped to 0.725 BTC each with international shipping, which will open sales at 22:00 pm on July 4th (UTM + 8 ). The Third Batch is most likely to be shipped before July 20th, but no more than one or two days delay may happen.
nice!!! I like the price drop, now it looks like I have to make room in my exhausted cabinet ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Afterall, if you're in batch 1 you could get as early as 7/10 batch 3 is likely after 7/20... so it makes sense that the folks in batch 3 aren't going to get the same ROI as batch 1 ... hence price difference. Personally... kudo's to Bitmain for doing this, I wish more manufacturers would. ... that being said... just to keep this question raised.... @Bitmain, please, please, please let us know the details regarding the s2/s3 upgrade (pricing availability ...etc) the answer to that question changes whether I buy several s3's and sell my existing hardware on ebay or whether I upgrade. (or some combination of the above)

One thing that I forgot in my original pessimistic calculations was the possibility that the difficulty will stay flat for next cycle or so, as new hardware that's being tested switches hands. Here's a quote that sums it up: https://bitcointalk.org/index.php?topic=674080.msg7657780#msg7657780If this is accurate, then my original calculations were overly pessimistic. I've redone the calculations for batch 3 (including the price reduction and delivery by the end of the month) with flat difficulty for the next cycle and it does look like I have a shot at ROI. That's with free power, buying a new EVGA 1300 PSU, and an estimated 1% pool fee. I've decided to go for it. If I'm wrong, or if Bitmain ships late, or if the difficulty goes nuts down the line, I can always press the Ebay ejector button.

Hi Community
I am new to bitcoin mining and want to order the S3 myself, I have a Radeon 5970 and after reading the threads see it is pointless to Bitcoin mine with it (Delivers 320mh/s).
Can anyone confirm if seller bitmain.antminer on ebay showing the item location/factory based in Shenzhen China is Bitmaintech.
Is £361 the reduced price? I notice there are two Antminer S3's for sale but for two different prices.
Many thanks for your time and all keep up the good work. I hope bitcoin sustains and changes things in this world

I`m not aware that bitmain have an ebay account, and to be honest all the sales on their site are in BTC, so to sell on fleabay and give a chunk to paypal etc doesn`t make sense. I would recommend buying from bitmain or an authorised reseller.

So..what PSU are you guys planning to use on S3 units? Is there any PSU that could power 2 of them with enough watts and cable slots (because 1 requires 4 PCIe cables if OCed of course), so 8 in total for 2 units.

EVGA G2 1300W PSU. 8 PCI-e connectors and plenty of power to drive 2 of them overclocked, or 3 running stock speeds.

thank you for your reply.
I notice that this seller on ebay appears to be selling many units daily of mainly Antminer S1s and S2S. However despite the Antminer S3 having shown sold more than a dozen units they do not appear to be shown in the sale history but I assumed this would be due to the rigs not being shipped out yet therefore the buyers would not have been able to at least so far leave any feedback saying it would have gone through successfully and they are happy with their purchases.
With the amount of sales and positive feedback it leaves me to believe this would be the only avenue Bitmaintech would be able to sell them individually for cash as I have no bitcoins and do not want to buy 2 units at least not yet.
Bitmaintech heeelp is this you on ebay? If not help me deter these fraudsters from defrauding your potential customers. If so reply and sign my S3 too :-)

There is no fraud in reselling it on ebay.
Many new and used units will be sold to newbies at a markup.
With PayPal "protection", I highly doubt that anyone would risk his reputable ebay account to try and defraud some small number of people.

I agree but I think with the telephone number that is in the ebay advert it appears to point towards Hashalot in Canada?
I will email Bitmaintech and see if they will sell to me directly

EVGA G2 1300W PSU. 8 PCI-e connectors and plenty of power to drive 2 of them overclocked, or 3 running stock speeds. You should be fine with any decent 1000W PSU, as it will most likely be able to even handle 3 units on stock settings. 3 units on stock voltage will pull under 980W on the 12V rail(s). Most 1000W PSUs should therefore be able to handle 3 units.

Of course Bitmain will sell directly to you... just go to their website. You will not, however, be able to pay in Pounds Sterling, or dollars, or anything but BTC if you buy direct. The folks on eBay are charging you a premium for the ability to pay in cash and to purchase a single unit, rather than the MOQ of 2 by Bitmain.

They do sell to you directly. What exactly are you trying to accomplish here?

Most 1000W PSUs should therefore be able to handle 3 units. Specs for the S3 claim 366W per unit at 478GH/s... I think you'd be stretching that 1000W PSU running 3 on it. 2 wouldn't be a problem, even overclocked to 504GH/s (which if I remember correctly pulls 390W). EDIT - it's 366W at the wall, so you might squeeze 3 stock from the 1000W PSU... still, a pretty tight fit for that PSU.

Specs claim 366W at the wall which translates to no more than 330W of 12V power per device. As most decent 1000W supplies are able to continously provide atleast 990W of 12V power, you should be fine with 3 at standard settings.

Thanks for the link. Your node looks very interesting. I'm getting 75 MS pings from our data center on the west coast, which is OK. But unless I missed a post, it looks like the S3 doesn't support p2pool yet. They've said they're looking into it and it's a couple of weeks out. Here's hoping that they deliver and get p2pool working.

And you should de-rate a supply's available current by 80% if running it continuously. I don't think advising people to run a PSU at 99% is a very good practice.
