Howwww so nice

When it wil. Be available

They said April 1st in the post.

Lol April 1st.... Stealth Troll?

If you're stuck on 55nm just sell the S1 underclocked and let people build up their 1GH/W hashing power from smaller cheaper units.

Underclocking the S1 doesn't decrease the production cost.  All it does is decrease the effective $/gh and makes them less appealing.  If buyers are stuck on GH/W then they should underclock the S1 themselves.

[ChuckBuck]

I'm not going to lie, this feels like a punch in gut.  Disappointed in Bitmain.  It would be something if it's new technology, but it's the same 55nm chips they use in the S1.  Didn't they sell over 33k Antminer S1s so far???  Their quote:

S1 is currently deployed in large binary trees structures within the private and public mining pools servicing 20.3% of the entire network hash rate.

They made a killing already, why not treat their loyal customers with respect?  Slap the same old chips but more of them in an ugly 4U case.  Very frustrating news, to say the least....

What does it matter?  The only competitor that beats it is Bitfury and they're super pricey.  I guess you could throw the Chinese Coincraft A1 miners in the mix, (maybe) slightly better efficiency but they want $6,000+     You could take the risk of buying an Avalon Gen3 for slightly more than the S2 as well.

As a customer of Bitmain, I don't feel that they owe me respect, I feel like they've already given it to me by a) being a standup business; b) adjusting their price daily to give us a chance at +ROI; and c) producing the S2.

If you don't like how they run their business, feel free to pre-order from HF, Cointerra, BFL, Bitmine, AMT, VMC, take the risk of buying from Avalon, or pay through the nose for Chinese A1 units and/or Bitfury.

Not to beat a dead horse or be confrontational, but what is so revolutionary about the S2 technology wise?  The enermax powersupplies?  The ugly silver case?  Please point out where they're pushing the edge.  The Lightning, Dragon, JT, etc are in the same space (1TH/s), are pricey at over $4k-5k each, but at least they're using 28nm A1s(stolen or not).

I'm just trying to see to value proposition with regards to the (same old)tech they're using.

You need to underclock the frequency and volts together (to balance H/W errors). But really I'm saying the the new 55nm chips have the same size package so just stick them on the same boards/chassis that everyone knows and loves. It makes no sense to re-design everything into a big silver box. Just sell 100GH/100W units @ 0.5BTC. If someone wants 1TH they can buy 10 of them for 5BTC and you ship it in one big cardboard box.

28nm vs 55nm means nothing. All that matters is "up-front cost", "date of delivery", and "power draw". S2 wins against every other product on the market.

Hmm...

1) Big Box
2) 1000W PSU for a 1000W Draw... Explosion in 3,2,1...
3) Pricy... 4BTC would have been a way better price
4) Still 55 nm chips

A bit disappointed. I wish bitmain stayed online to answer a couple of questions, especially on the PSU front.

1) Im sure that the box is a prototype. the final design will probably be a bit smaller to fit a 4U standard, and anodized/painted to look a bit more professional.
2) Its very likely that the draw at the wall is 1000W, and/or low enough that the PSU has sufficient headroom. it seems unlikely they would miss an obvious technical limitation like that
3) I agree. Price should be roughly: 5x antminer (probably around 0.85BTC by april 1st) + $200 PSU + 15% premium for lower power usage = 5 BTC.
4) who cares, undervolting them clearly does wonders for the efficiency

If these were priced at 5BTC, I would buy 1 or two. but at the current price, it makes more sense to go with the more modular antminer S1

I have  2 high quality 1000 watt psu running 4 s-1's .  my need for the psu is 0

So an good enermax cost 150 usd shipping it is 20 usd.

 Sell me a 1th unit without the psu.

reduce the price to 5.6btc maybe 5.5btc   I would want one.


 the fact that it is old tech does not matter. the watts per gh matters to me.   my  4 units do 720gh at 1440 watts.

I can do a new ones with my one of  2 psu's and run 1000 gh at 1000 watts.    with the summer coming dropping watts from 1440 to 1000 will be nice.

[roy7]

How can it draw 1,000W and you are only supplying a 1000W PSU?    Won't the PSU overheat and trip?

You have to calculate the efficiency of the power supply. If at near max load it is, for example, 90% efficient, then a 1000W draw at the wall means about a 900W pull from the power supply by the hardware.

The rating for a PSU is normally the max power you can draw from it to your hardware, not the max it will pull from the wall. That will be higher based on efficiency of the PSU itself. A 50% efficient really old 300W power supply might pull 600W from the wall to run your 300W of hardware.

I would love it if they're using the same boards as the S1, but I doubt it. If they're running the chips that much slower, I am sure they've redesigned the boards to increase the number of chips per DC/DC power supply and lower overall cost.
Granted, maybe they will. Those regulators are being pushed to the very limit on the S1s. They would see a decent boost in DC/DC efficiency by running them with less power and cooler.

I'm waiting for a price dump on next batch Now, my opinion, S2 is overpriced.

I have  3 high quality 1000 watt psu running 6 s-1's .  my need for the psu is 0

reduce the price to 5.6btc maybe 5.5btc

Sorry, where can you buy a 1000W Gold Enermax for $150?

5 btc is the right price

[pjcltd]

Way to much for 1Th/s
should be around 3 BTC if that

Agreed, like I said on the Tesla forums, the Tesla should be around $20,000...

I know i said 5BTC a few posts up, but 5.5BTC is actually reasonable as well IMO. However, >6BTC is a little bit of a stretch unless it comes with one hell of a coupon code.

and Pieh0: shut up. 3BTC is insanely low and I would spend all my earnings at that price for the guaranteed profit

 you are correct i can't find one lower then 200.

but with 3 of these what do I need it for.

plain and simple dumb move to force that psu on us.  we purchased  lots of antminers from them and now  they want to stick us with  psu's many of us don't need.

and I want the new gear but I feel that the psu is a problem for me.

Lucky for me I dont pay custom fees, and only pay $0.055/kwh average so I will make ROI very fast even at 6btc or higher.

Congrats for not getting the sarcasm, $20k for a Tesla? Come on...
