Hey I purchased an Antminer S1 but in the order  it says Payment confirmed  BUT  I'm unsure about the following

1.45 BTC   Pay:1.45 BTC Confirm:1.45 BTC   Paid Unshipped Expired   2014-02-03 11:57:53.0   View

Why is the status  Pay Unshipped Expired ?  as  my payment has been confirmed  both on bitmaintech site and Blockchain

Cheers

Considering buying one of the AntMiners (was going to buy about 10 of them), but it said it's 18 BTC for just one miner. What... ?

Where do you see that?
It's currently 1.45 BTC each on the Bitmaintech site.

You're probably looking at a box of 500 U1 miners

18BTC is for 500pcs U1.

ok lenny! thanks! I will pay more, i live in italy(country of tax!). Friday order 2 antminer also for me!
how many days for delivered you?

It will take 3-5 days for you, via UPS Worldwide Express, unless your Customs will hold it for checks.

Just remember nothing is shipping till the 8th of Feb.

I have ordered 2 pieces from this link https://www.bitmaintech.com/productDetail.htm?pid=00020140107162747992Ce5uBuxW06D6

Question for you PSU gurus out there - do you think 2 ANTS OC'd @400mhz/200ghs will run fine/safe on an OCZ 1000W 80+ gold PSU rated @90% efficiency?  They will be on their own 20A/125V circuit.

Thanks in advance for any guidance.
Yes, that will be no problem.

Curious to see how that's no problem when a single OC ant @ 400Mhz already uses over 500w
(let alone the indicated 1000w is not only 12v and you should never push a PSU to it's max for a long time)
First, I haven't seen an S1 yet that pulls 500W from the wall. Not saying it's impossible, but that would be a really poor unit. The closest of any of mine was 440W for 400MHz/203GH/s from an old Bronze Corsair VX450 that had a big 4 ohm resistor pulling 1.25V from the 5V rail to get it to turn on since it's an old group regulated design. That ran fine for half a week until my server PSUs came in.

Second, even if you had two terrible S1s that really do pull 500W each from the wall with a 90% efficient PSU, you're still only drawing 900W DC and you're only loading the PSU to 90% capacity.

I also have two S1s running on an 850W $40 HEC power supply that have been running over a week and averaging 202.5GH/s and 200GH/s over that time.

He'll be fine with that 1000W PSU.

Don
Why do you think they are in stock and dropping on price constantly?
None of the antminers I've received showed the slightest evidence of being used. The reason they are dropping prices is that they're selling these things near or beyond the boundary of profitability, and so as more hashrate increasing days go by they need to lower the price to keep it from being an obvious loss to everyone.

My miner didn't show signs of being used either, and I am planning of ordering more.
Don't get me wrong but I am not stupid.

And when this guy: http://eligius.st/~wizkid057/newstats/userstats.php/1Nbq2XZaRsKknf5fcT2wTXvBS31PaUWSeX

Had a mining power of 252TH 2 weeks from now, 2 days from now more than 520TH and today only 450TH (btw 3 hours before it was 490), then don't tell me pre-order or any kind of mining equipment has not been used yet. For the sake of testing purposes let's say  Roll Eyes

Let's be honest here, it's nothing personal it's just business.
You would have done the same.





I would think he is mining on his own or it is a company not selling to the public.

I am currently running 2 ants fitted with extra fans and o/c @400MHz/203GH/s on an EVGA 1000P2 (80+ Platinum) which pulls 795 Watts at the wall (on 240V in the UK).
So you should have no problem I think.
You might be pulling a bit more at the wall (~825Watts?) but well with limits.

It really does depend on how good your PSU is.

15A * 110V = 1,650W

No, no, no. Do not run a circuit at 100% 24/7. You max 80% continous load.

15 amp circuit: 12A @ 120V = 1440W.
20 amp circuit: 16A @ 120V = 1920W.


The mainswitch is 80% rated but I think the branch circuits are 100% rated.

If the branch circuits where also 80% rated then a 200A service would only be good for 128A continuous.
No, your branch circuits are rated for no more than 80% continuous use. I don't know why you're derating the main service twice. You should derate your main breaker as well but the branch circuits don't affect that, it's just a function of the breaker. You can still have 16 10A loads on that breaker and be safe. Each branch shouldn't be run more than 80% except intermittently (eg, a big temporary draw like a microwave or kettle) though, and since mining is hopefully 24/7, no more than 12A on a standard 14 gauge 15A branch.

That being said, I wouldn't run even 12A continuously on a standard house branch circuit. 14 gauge wire has a resistance of 2.525mOhm/ft, so if you have 50 feet of NMD-90 between the panel and the outlet you are running through 100ft of wire (hot+neutral). 12A*12A*0.2525Ohm = ~36W burning up just in the house wiring.

Short runs of thick wire, why waste power when you don't need to?

I know for a fact that 99.99% of all mainswitches are 80% rated.
You are correct, and I didn't say otherwise. What I said is that you don't derate it twice. Derate the main breaker 80% for continuous use (160A in your example), and derate each branch by 80% (12A).

It appears that you are also probably right.

I work at a power utility however, I am not an electrician so I don't know for sure.

My incorrect response that started this sub-thread woke me up last night but not enough to come and fix it. Other countries rules are different from the UK and I would think that Syke's 80% rule of max continuous load would be good enough as a guide for most of them.

In the UK the 240V and fused plug system and ring main circuits that are just about ubiquitous safely allow for greater loads than most other counties and if you know what you are doing you can run a ring main circuit at 100% load as if it was a heating circuit with out any problems BUT most people would not have a clue to work out how to run it as a heating circuit so if you do not know exactly what you are doing then follow the rule for other countries, load to 80% of rated current and stay safe!
