I have some questions about the BitMain AntMiner S7

[goldchain]

Hi to all Bitcointalkers,

For your information, I just bought an used BitMain AntMiner S7 with about US$600. Below here's the specification for the AntMiner S7:

Bitmain S7Hash Rate: 4.05-4.86 TH/s ( depends on batch)
Power Consumption: 1210 W (at the wall, with APW3, 93% efficiency, 25C ambient temp)
Power Efficiency: 0.25 J/GH (at the wall, with APW3, 93% efficiency, 25°C ambient temp)
Rated Voltage: 12.0V+5%, should not be less than 12.0V
Chips per unit: 162x BM1385
Dimensions: 301mm(L)*123mm(W)*155mm(H)
Cooling: 2x 120mm fan
Weight: 4kg
Operating Temperature: 0 °C to 40 °C
Network Connection: Ethernet

The seller told me that I can expect to mine around 0.039 Bitcoin/month with this AntMiner S7 (not sure it's true or not, since the difficulty is getting harder and harder...)

I was wondering, how to calculate the electricity for power consumption? Let's say, if a 1kWh costs me US$0.15 here, what is the estimate cost I need to pay monthly, if I open the AntMiner S7 24/7?

Looking for some genuine feedbacks, thank you very much.

It takes literally less than a minute to google ‘electrical cost calculator’ or pull up a mining calculator and see your electrical expenses for a miner. Ask the forums for more technical questions than this. Hint: Rapidtables has one.

Oh, thank you very much for the suggestion. Maybe, the best way for me to find out is to run the BitMain AntMiner S7 for a whole month (I just started it up this morning)

I will get back and update this thread, once I get the final outcome
