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.

'The right to privacy matters'

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.

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

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.

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.

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. Roll Eyes

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.

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.

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:

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.

Just wait till be hit 12.5 BTC per block.... then it its time to greet

3) Ok, I might have been a bit aggressive with my price point.

Anyway, with the hashrate that's getting deployed this year, you better ROI fast with these because in a couple of months they won't pay your elec bill anymore.

Sure, a lot of hash is in the works, but a lot of hash is always in the works. It's all relative. Each of us is going to have to make our own predictions and crunch numbers. These are going to be a lot more attractive to people with cheap power who have reached their electrical load capacity vs. those with higher rates and/or have not reached their current capacity. One thing is for certain though, I like having the shipping from stock options vs the pre-order model. Hell, it looks like these units are a better deal than going the Cointerra route.

3) 4BTC? 5 S1's cost ~4.96BTC, have less chips and no PSU. This ain't a charity.

...

It still has to be a valid purchase though, the S1's made that and returned ROI reasonably quickly @6BTC ROI will be 9-10 months away.

Slush's pool just added 220TH here the last couple of days and dropped my return per block down by 20%. With more power being added, 9-10 months away is generous and in scheme of things is way too long.

Which should balance out with an increase in blocks being solved per 24 hours.

I'm not saying that I like or dislike the S2 pricing, just that 4BTC didn't make sense as a talking point.

4) This is no surprise. I'd guess the next model (S3?) Will have a smaller process node.

We all need to remember that was a prototype. Would like to see what the final product would look like as of right now, it's a broken link on the page. Might as well have a picture of the Riddler up there. I do agree that the price and the power consumption doesn't make much sense compared to the S1. What magic is going on in that box for it only needing 1KW PSU?

I have an email from Bitmain a few weeks back saying till will be releasing a 28nm very soon with mass production mid april.

This box sent with a PSU will cause massive issues with customs and the custom fee will be $$$ or £££

Yes its good to have such good power in one box and easy to use but cmon bitmain using the same chip and just using more of them is not really more efficient when you have to take other things into factor.

You will be paying plus 7 BTC to get this thing imported.

also 4U looks more like 8U

These box designs are not nice but hey as long as its cheap and good and fast I don't mind but the price must be right.

These will never ROI even if BTC increases by 10%
