Bitmain S7 Antminer Bitcoin mining farm ***update***

I was able to connect my other 2 S7’s plus an additional s5+, or rather a fragment of an s5 +. What you see is the center portion of an s5 +, that is running at 2.5 Terra hash and pulling 10 amps. So not quite as efficient as the s7’s. But still profitable at Bitcoin’s current price. So my Farm now has 19 S7’s the one S5+ plus and is hashing at around 94 Terra hash and only pulling 200 amps. I know I say only but that is a huge jump in efficiency from just 6 months ago where it would have taken between 2 to 3 times the the amperage to get the same hashrate.
