If UPS lost it, assuming Bitmain insured it correctly they would be reimbursed by UPS.
Should be fair to refund customer.
If unit was received is different as they will warrant a replacement for anything defective.

Btc price could just as easily drop 150 to 300 or up 150 to 600.

Just buy the alt rigs, unless you want to mine direcly with coin terra 1 th.
But, I doubt anyone will lower the price around 2,000.
1th will go under $1500 in 3-4 weeks that's cool - who do you think will have it out first? Probably bitmain will reduce s2 to that price level first why would I spend that much for 1 ths? - I can build a 1ths unit from boards for $1,000 - it will consume 1,100 watts though. I meant a turnkey package. I am assuming you are talking about Bit Fury boards, which are over priced as well and thats why they are blowing them out now as they work on a new design. Still needs a power supply, interface, controller and power cable. the addon stuff if cheap and I have it all.... it's still a good deal Prices realistically need to come down to .50 per GH to give miners a chance, but this is the point at current manufacturer cost. big problem. |

Lets analyse it a bit more: A short good news for the S2 buyer is that we will let the S2 to upgrade to 1.8TH/s or 2TH/s at very low cost which you can only image now in the August or September. It still depends on many factors to let us achieve that and detailed plan needs to be drafted, But we are very confident that we can make it.
-"upgrade to 1.8TH/s or 2TH/s at very low cost " I believe is more like a hardware upgrade, rather than a coupon. Well they better start moving faster as diff will ne 10.4b next week. But then again no one else has a better $ per gh solution either. |

Consider the efficiency of these units 70-75%? and you can calculate power savings 6 months or a year down the road if you are using to mine btc 24 hours a day.
Ive not used that specific unit but I haven't come across a server grade psu made in the last 3-5 years that has been below 88% efficiency personally. As we know psu highest efficiency is most likely at 50% load and not as efficient at 20% or 100% load. You can see here alot of comparison of name brand server psu: http://www.plugloadsolutions.com/80PlusPowerSupplies.aspxYou will notice the majority is at Bronze 85% and less. And at lower load 20% or highest load 100% Brozne 85 is only about 81-82% The second highest category is regular Bronze only 80% efficiency. This is not even including the many many server psu on the market that dont even have a 80 Plus rating (probably Chinese, or fake) : so they are much less and into the 70% range obviously. You are correct I tested my Dell server PSUs and they use 860-870watts per 2 S1s at the wall. This is the exact same as my thermaltake bronze PSU. My EVGA and Corsair golds use exactly 800watts at the wall for the same 2 miners. Doing the math the difference per month in electricity would take a long time to offset the initial savings savings of buying a server PSU. The 60 watts savings for the Gold psu per day at .16 per kwh running 24/7 for a year would save $84 For platinum about $125 a year. Amazon for $170 Platinum Corsair 860 http://www.amazon.com/Corsair-Professional-860-Watt-Platinum-AX860/dp/B00A0HZMKG/ref=sr_1_1?ie=UTF8&qid=1400395186&sr=8-1&keywords=corsair+platinum+860So $45 for plat psu 860 watts and great resale value I think is good deal |

so whats the consensus on a PSU for the ants / what's the most popular choice...? what sort of wattage do you need for factory and / or OC'd units...?
If you have some spare time for modding, server psu is the cheapest choice that you can find (Dell PSUs are the most used) i really don't have any time to dedicate to modding... just looking for a cheap PnP... what wattage is recommended for factory or OC'd ants...? It's not so much wattage, it's amperage on the 12V rail. An OC'd S1 uses about 32-33amps on a gold PSU on a 115v line. Make sure whatever you get has enough juice on the 12V line to run as many Ants as you are looking for, and you should be fine. M so if i were looking @ something like this http://www.newegg.ca/Product/Product.aspx?Item=N82E16817139060 would that cover the power source needed to run a factory ant? what about an OC'd ant? I can't tell. There are no specs about the 12V rail. I'd proceed with caution. If you intend to drive more than one ant, and are prepared to spend $100 on a decent PSU, consider this one: http://www.newegg.ca/Product/Product.aspx?Item=N82E16817182063Will drive 3xOCd S1s with room to spare. M can't shell out that much thats for sure... i'd rather not hook up more then one ant to one psu... so i would need about 6-8 psu's total... anything recommendations in the $100 range if possible would be appreciated... 3 PSU = 3 power cords, 3 boxes, and extra cables If you're going to do $100 a PSU, the one above will save you $70 right out of the box. However, as others have said, there are cheaper ways to do it. M Here is the one: http://www.ebay.co.uk/itm/IBM-74P4453-Bladecenter-E-2000W-Power-Supply-zj-/261410878512?pt=US_Network_Switch_Power_Supplies&hash=item3cdd4d7430Price is so low its almost stealing. Cables will be near nothing and only time to mod this one. This one will run 4 miners OC. Consider the efficiency of these units 70-75%? and you can calculate power savings 6 months or a year down the road if you are using to mine btc 24 hours a day. |

Thought I'd provide some information on my setup of 2 S1 miners in case it is helpful to anyone.
I am running a single HCG-850M (Bronze rated) power supply that I picked up for about $70 shipped after rebates (currently $90 at newegg). I ordered an extra set of PSU-PCI-E cables from Antec for $6ea, shipping was free (the PS has connectors for 4 cables but only comes with 2). I could not find the cables anywhere else. Other brands' power supply cables that I tried did not fit. This PS has an 840W 12V rail that is enough for 2 S1's.
Using an inductive current probe, I measured the current running to each blade of the S1 and it was just under 16A overclocked at 400Mhz. Since the cables are 18awg, this is why you cannot use the power cable's daisy connector because the antminer would be trying to consume 32A of current through such small wires. Estimating an actual voltage of 12.33 V (I did not measure this), the current actual power consumption of each blade would be 190W-200W.
Measuring power consumption at the wall for the supply with each S1 running 400Mhz plus a 5 port basic Ethernet switch I'm seeing 870-880W. It seems the overhead of the supply is approximately 80-120W which puts the PS efficiency somewhere in the 85%-90% range.
The antec hcg is indeed a bronse 80. Yes. |

What do you mean by a receipt from local bitcoins sorry?
There are alot of people there that scam sellers by sending fake deposit receipts to receive bitcoins. Some of the altered receipts are very good photo shop work. |

The era of small bitcoin miner was gone, no more chance for house hold miners, only data canter remained.
Data Centers will incur too much cost like electricity and maintenance. The ones run by manufacturers will be less costly As the manufacturers can produce the most cost efficient systems. But alas, the day is coming soon where machines will cost more to run in electricity than the btc they mine. |
