I dont pay for power. What type of rig would you build?

[hollaent]

So i have been bittin by the bitcoin bug also. Im fairly new to this and of course i have made my mistakes in jumping on some bad ideas.

I live in NYC in a Coop (its like a condo with electricity included with my maintenance) so power is never an issue for me. Summer time i usually have the AC on 24x7. After i started reading about bitcoin and electricity not being a factor for me i decided to start the easy way and buy a BFL Jalapeno. I did get a good deal and got a 10gh for around $250 on Craigslist. (ebay has them going over $800 right now). But i wanted more so i decided to read more on it and started to scrypt mine. I got 2 asus R9 270's over clocked and doing over 900 mhs. But the fans blowing on them is getting a little noisy.(AC on the winter makes it too cold in my apt... lol.) Im now thinking of trading them all in to get a antminer s1. And if that goes well ill purchase some more.

I guess my question is, if you didnt have to pay for power what would you build to generate some profitable bitcoins?

Probably a KNC miner (if you can get one at a good price) or an Antminer S1.  The Avalon's put out a ton of heat and consume a lot of amps, even though you have "free power", your circuits are going to be limited to 15 amps for standard outlets and 20 amps for kitchen appliances, which means if you place too many amps (watts / 120), your going to pop your breaker. You also have to consider the heat, right now it's winter in NY, so probably not a big deal, but in the summer you could be dealing with a big issue when your AC kicks on.

Pretty much what clover said. The Ants are loud, I have 5 of them in my office at home. They are nice space heaters as well. Most of the new stuff coming out now, Dragon 1 TH/s and more soon, will pull less watts. 5 Ants OC'd to 200 GH/s pull about 450 watts each instead of 1000 watts from the Dragon. I am gonna hold what I have for now and wait till some of the newer stuff starts dropping in a few months.

Good luck!

Just a heads up, but unless you live in an ancient building where all units share a single meter (unlikely) your coop board will notice a power spike from your unit, probably assume you are growing pot and running big lights, and have the police kick down your door

OK... so maybe that's a worst case scenario, but be prepared for a letter from the board if you plan to mine seriously...

[minereu.com]

even if electricity is free for you, you still need to worry about power consumption.  Check how much amp your power line can support before your rigs trigger fire.

[hollaent]

Thanks guys for the replys, "Cloverme" im defintly going to look into that wattage info. "daddyfatsax" Dragon1 im going to look into. Thats if its still avail. "windpath" its an old building so i dont think they can see what im doing but ill ask the maintence workers they would know better than me. and "minereu" yup your right i might invest in an electrician to figure out whats the most i can put into these jacks b4 i go huge scale.

[Skaterdiejosh]

You just need to figure out couple 20 amp circuits in your unit . Should be at least a couple for all your outlets in the apartment. Just make sure you only run a max of 2000 watts per one ...

[smooth]

Depends on your budget. If you are thinking about maybe getting "an" S1, then I'm assuming your budget is less than $1000. That being the case, don't worry about power at all. (You won't even max out one regular 15 amp outlet with anything you can buy for <= $1K.) S1 is probably the best bang for the buck right now.

Avalon3 1TH/s or A1 is lower power comsuption now.

 here  do this  above ^


 or just buy this kit


https://www.minersource.net/products/bitmain-s1-dual-blade-180gh-400w-asic-miner-1-2-3

  and a switch from newegg


http://www.newegg.com/Product/Product.aspx?Item=N82E16833156387   

 this will pull under 770 watts   it will hash 360 gh undeclocked

the gear will be in your house by wed or thur.    ships from colorado.

since your power is free just mine it.  use this calculator for pay back

http://bitcoinwisdom.com/bitcoin/calculator


I punched in 20 % diff.increase

 1 cent and 1 watt

1800 cash setup

and I have usd  profit in 5 months  . 

over clock  and you have 400  gh giving you  usd profit in 4 months

[smooth]

The switch is a bit overkill unless you have other equipment to hook up. You can get a decent 5-port switch for $30.

Get a Kill-A-Watt and map out your breakers so no one circuit gets overloaded.

Even if the electricity is technically free, if they notice a sudden huge surge coming from your place they will probably say something like "Dude... Srsly?"

What are your plans for dealing with the heat?  I'd suggest running extension cords to one empty room and have the windows open with box fans going.  Trying to AC cool the room will just waste power and be ineffective.

This YouTube channel "Studentoftheretard" has an EXCELLENT 7 minute long video on electricity management in a grow room, which is directly applicable to the needs of a room full of mining PCs.

[techgeek]

It really depends on the budget you have at the moment. But starting off to know electricity is not a main concern for you since most is, I`d start with the new Ant Miners that do 180-200ghz. The setup can be through wireless as well.

The reason I dont point out Coin Terra 2 TH is because due to people mentioned problems on performance not delivered of the 2TH. They even tweaked it which mentions the performance 1.2, and they paid a huge premium on the loss as well.

I`ll link the here once I find it again.

As far as Cost for GH/S ANtminer will probably be the best choice for a LONG time to come.  That's because its a Chinese company that doesn't have an office in the middle of San Francisco to maintain (Hashfast -_-).

55nm will be the cheapest cost for the forseeable (AT LEAST 3-5 months) future, just because a lot of chip makers are fabbed to make 55nm quite easily, and only the big boys are making 28nm and 20nm.  The only benefit to those is power consumption, really, I mean sure they hash more, but lets say 5 55nm hash at the same speed as 1 28nm, but a 28nm cost 10x.... my maths aren't fully correct, but from what I've seen, power costs ignored, and opportunity costs realized, you'd get may more BTC for your $

Suppose you have a 75 watt panel and you use up 62 amps of it for mining that is 7500watts. At .1 kw/h your landlord would get a $750 electrical bill and probably kill you. Realistically on a 15 amp breaker you can run 1700watts +-. That gives you plenty of room to mix and match asic rigs.

I wouldn't go crazy as it is better not to get the landlord after you and you could still make some great profits.

Not necessarily. In some older buildings there aren't even individual meters for each unit, so the landlord has no idea of anything other than the bill for the whole building (which will likely be much more than $750). I have no idea if that is the case for OP.
