I see post after post where mathematicians calculate profit or loss based on speed and difficulty, but the biggest factor that will get in the way is LUCK, the POOL LUCK has been destroyed by manufacturers and the private farms. Bitmain is a contributor to this as well. The difficulty is rising in leaps and bounds based on network speed but most of the public pools combined hash rate is getting left in the dust! Oh except when Bitmain or one of the other Manufacturers decides to raid a pool by jumping in with a Ph/s or two for a couple of hours while "testing". Crunch the numbers all you want, till you start adding in the Variance and LUCK of your favorite pool, those calculators are meaningless.
If these units were only $50 cheaper, then the cost of 2 units plus a decent power supply (est. $150) and free power would mean a possible fiat ROI in a couple hundred days and maybe a small profit in 12 months. This is with the coinish calculator, 1.2% per day difficulty rise, 1% pool fee, and 30 day delivery (because these things never ship on time).
Too pessimistic. With free power these will easily break even and make a nice profit.
I don't see how. If anything a 16.8% difficulty adjustment every 2 weeks (the default on the coinish calculator currently) is reasonable, or somewhat on the low side. And given that any purchase made now would be in batch 2 (which is supposed to ship on 7/20) it could easily slip to the end of the month before receiving the units (which is on the other side of the next difficulty increase).
What I come up with (after buying a decent power supply for $150; yeah I can go cheaper, but PSU's are not a good place to scrimp) is no break even point. The loss after 12 months is $74.
With over clocking to 1 THs for two units the loss after a year is $25. Tantalizingly close, but not really there...
Of course this assumes that Bitcoin prices stay the same, which is unlikely. Hopefully a year from now we all hope Bitcoin is up from where it is now.
At this stage, I'm probably better off sitting on my Bitcoin and watching my existing Scrypt ASIC rigs ride into the sunset. I have free power, so these will never get unprofitable. They will just get really boring ;-)
Don't forget the fun of RMA'ing these back to china or wherever for repair. All of my miners had or have some die failure out of the box, this stuff isn't easy folks and I'm afraid to say if you haven't made your profit in BTC by now you won't do it by mining. Your new window of opportunity is buying BTC directly, but you don't have to take my word for it!!
With an S1 overclocked to 400Mhz, each PCI-e connector consumed just under 16A. With 16Awg wires (x3), this is about the most you want to run through a single PCI-e connector. This is not something to take chances with. If you're going to overclock the S3, use 4 PCI-e connectors, don't skimp and try 2. Regardless of specifications, you never know what shortcuts your PS or cable manufacturers may have taken.

you should get 4 850 watt psu's your psu's should only be running about 60% to stay in the efficiency range.
thats if you get poor quality psu's
if you calibrated your pricing so that miners made a little money, you would sell a lot more units.
You guys need a new hobby. S3's are flying off the shelf. There is exactly ZERO incentive for Bitmaintech to do anything to 'bump' sales. To even make such a statement is laughable.
They did about $22,000,000 on day one.
Wow. I'm in the wrong end of this business ;-)
Assuming a 4 or 5 times markup, Bitmaintech is the only one who is a real return out of this deal.
Granted they actually might not have incentive to lower their price when people don't realize they will not get 0.74 BTC out of these things. Difficulty has been increasing ~10-20% every 12 days.
If difficulty stopped increasing now it would take over 50 days to get your BTC back but when it rises 20% every 12 days you are screwed to the nth degree...
I've got a Corsair RM850 which is running two over clocked S1's. I was thinking of getting two S3's, and was wondering what PSU to get, I would like to get a PSU that has 8 PCI-e connectors. What would you guys suggest for such a PSU?
If you like your Corsair and want to stick with the brand, the RM1000 and the AX1500i, AX1200i all satisfy your requirements.Yes, I do like Corsair. Obviously with 4 PCI-e per S3 we are overclocking, so which of those three would be suitable for overclocking the S3's?
If we consider the maximum Overclocking, One S3 may consume upto 554Watts.
Then two S3-s it will add up to 1108Watts, Since it will be running 24hrs yu need to add some margin above the maximum.
So, AX1200(100.4A*+12=1204.8W) will be enough no need to go to AX1200i, its a little more expensive.
From the Corsair AX1200 Modular PSU you will get 8 PCI-E ports and a 90% efficiency.

So I've ordered 4 of these S3's out of the batch1 and will be running them off of a 1000w Rosewill Capstone 80+gold and a 850w evga G2 gold
out of the specs the rosewill has 6 pci-e and the evga also has 6 pci-e
knowing this I will probably only be able to overclock 1 per PSU on 4 of the connectors, and the other s3 running stock on the remaining 2 connectors

I was so close to ordering 7 of these S3's ~3.3 TH for 5.18 BTC last night until I ran the numbers and realized they would only generate 0.097 BTC/day for the next 8 days before the next diff increase.
Its crazy when you think this is the best deal out there for mining equipment and it still doesn't ROI. Especially when you add electric costs and PSU's.
28nm is good tech and I have had 3 Jupiters running since Halloween of 2013, they (all 3) made 1.1 BTC /day back then and today make .037 BTC/day today.
I had 5 cointerras when they came out and they overheated terribly even with AC pumped directly to them. I had to dump them for cheap before coin terra gave them away, I was lucky.
The KNC's (oct jupiter) don't need AC and I am thinking the same goes for the ANTMINER S3. I have the KNC's in my garage vented to the attic but no AC and they run fine in the summer. Garage temps hover close to 100F but they run fine.
If Bitmain can lower their price by half I could see getting some but at .75 btc I am WAY better off buying BTC from Coinbase….

ROI waaaay too tight for me to buy this....
Good luck gamblers.

I have personally seen the ugly side of this connecting an EVGA 600 and watching the cables literally burst into flames.
Whatever you are planning to do, please everyone, put safety above EVERYTHING else!

As interested as am in the S3, I just can't bring myself to do it. Even with free power (I have access to a data center), two S3's plus a PS will never ROI.
I know that this is not news to anyone, and that people have strategies for making up the difference, including selling the hardware in a few months. But that's a PITA.
All I want is to buy some hardware, have some fun, and make a little profit supporting the network.

As much as I want to feed my mining habit, I just can't do it. It's too bad because it wouldn't take much to win me over.
Bitmain, I understand that you have to maximize your profits. But if you calibrated your pricing so that miners made a little money, you would sell a lot more units. The people like me that are sitting on the sidelines would jump at an opportunity to break even, or make a little profit.
If you had bought BTC two weeks ago when the value was just above $550 per BTC you would be getting almost a $100 discount right now.
