Topic: S9 powering... USA (Read 976 times)
ready to just bite the damn bullet!!!
Bitmain STILL doing the BCC right now?
??
??They never stopped - this batch still hasn't sold out yet, which tells you a little bit about the demand for BCC.
Usually their crypto only sales last a lot longer than the wire ones anyway.

What is the price now ? roi in how many time ?
Thanks .
The price of an S9 right now is currently $1265 direct, with no btc accepted (shitcoin cash is though, probably to force prices of BCH up) with shipping in November. ROI is something you must calculate yourself, as only you know your electrical cost and other factors like PSUs. Nobody’s going to give you all the answers. Mining calculators are available online to approximate things but they dont often factor in difficulty increases. Thanks .

Just throwing this out there....its not that hard to get a 220 circuit wired up to run a better power supply. Its not like the USA is limited to 110 power only....
yeah 1x 30 amp 220 circuit in your garage will allow 4 s-9's or 4 avalon 741's with power to spare
a 30 amp circuit using 10 gauge wire derates to 80% or 24 amps for 24/7/365 use
so 220 volts x 24 = 5280 watts on the low end
and 240 volts x 24 = 5760 watts on the high end
a used pdu on eBay is about 40-50 bucks

4 of these psu's use code slush about 500

4 of these cables 20 dollars

this wall receptacle 9 dollars

so under 600
plus you need the circuit installed either diy (dangerous do not complain if you die doing it)
or hire an electrician to put in a 30 amp 240 circuit breaker using 10 ga wire and using the plug on eBay above -
cost varies the longer the run it cost more as 10 gauge is not cheap

that makes perfect sense.
I think I'll start buying here.

I have just bought a GPU on Ebay. You can look out for AmityLabs for a nice one.
I recommend always to use server level PSU's, they are made to last and to be 24/7 on.
There are A LOT of model and certifications, I would recommend you the platinum level one, they have the best quality output and you will spend less money because they are more efficient.
that makes perfect sense.

i think bitmain PSU could handle D3 in USA.
buying bitmain psu's for usa locations is just plain stupid.
I can give a dozen good psu sellers located in the usa.
I can not give a dozen good asic sellers located in the usa.
so
I buy my asic's in china
I buy my psu's in the usa
I know it is possible to show buying a psu from bitmain makes sense in a few cases it may.
But I never purchased a single one for them. and unless they want to send them for free I don't want them.
here is a case
i buy 24 from them cost me 3000 plus and I will be paying import tax so at least 100 more = 3100 plus
and they do 1200 at 120 or 1600 at 240 so if you have 240 you could run 24 s-9's
I can go to parallel miner buy 6 of these http://www.parallelminer.com/product/power-supply-kit-for-2-antminer-d3-dash-miners-94-platinum-high-efficiency-200-240v/
for 736. place 4 separate orders a day apart total of 24 pieces for under 3000 so I save money and I have 2400 watts x 24 = 57600 vs 38400 watts. and delta makes dead solid psu's
Just don't buy psu's from bitmain if you are in the usa. and have 240 volts. or 120 volts
I understand that, but I also read that you can put 2 PSU's (110 or otherwise) on 1 Miner correct?
can I run 2 of the PSU's on 110? is that ok to do?
do you live in the usa?
buy these
http://www.parallelminer.com/product/platinum-94-1500-watt-power-supply-kit-for-antminer-d3-dash-110v120v/
use slush for 5% off
buying a psu from bitmain is not a good idea if you live in the usa
or buy 2 of these from sidehack
http://www.parallelminer.com/product/94-platinum-1200w-power-supply-kit-for-baikal-giant-miner-x10-110120v/
sidehack has good gear
this is the way to go . I recommend 110v to OP, why? because he clearly don't understand the difference between 120 and 220v.
to have two 110v PSU's don't make 220v. it doesn't work like that.
The miners and the PSU are two different things. Miners use DC and PSU needs AC. They transform the AC to DC. Some PSU have a switch so you can select 110 or 220.
good luck
D3 yes, S9 no
i think bitmain PSU could handle D3 in USA.
Awesome I just messaged him................. Miner hosting too!!! great find, thank so much guys
