Hello. New to mining and this forum. Would appreciate some help...
Got an Antminer S9 rig delivered today (December 2017) and the Bitmain APW3++ PSU.
I also borrowed an Antminer S7 from a friend together with his Bitmain APW3 PSU.
Both are brand new out of the box (for some reason my friend never bothered to hook up the S7 rig).
I placed a meter against the wall socket and turned the S9 machine on and the power draw goes up to 3100W. I thought I had a faulty S9 but when I tested the S7, I get the same result. Both rigs are consuming around 3100W EACH.
On Youtube, I see videos of guys showing that the power consumption should be 1300W-1400W per rig. I am wondering why both my rigs are drawing so much power.
I tried swapping the PSUs around and no luck. It seems unlikely that I would be so "lucky" to get two faulty rigs.
I checked the meter against a standard 1100W heater and it gave me the correct reading so I do not believe the meter is faulty.
I am wondering is it because I am in Australia and we are using 240V? Any Aussies out there with the same issues?
