Good point. May be you can put some light on this situation ? Like what is actual D3 operational power draw from 220 line so I can calculate power requirements for 60 units.

I mean for Bitmain power supply to produce 133 AMPS on output it needs like Gauge 12 wires or something.

Anyhow. Help out if you can.

Thank you so much. I am in NY tri-state area so that's exactly what you'r talking about. I guess I more worry about exact numbers. Like that 930 I saw in the video, but IS IT 930 ? May be it's more a lot more or may be less. After all PSU is rated 1600WATTS running @ 220v why would they make is so OP if it only really needs to be 1000WATT rated @ 220v unless they're really good maker and doing something like 1.5x of maximum power needed for longevity of PSU, then it make sense.

Right now I am looking for 300 AMP service but I hope once everything is there and installed , I wont bite my nails asking myself questions I should be asking now. Like I said according to my calculations I shouldn't need more than 300 AMPS. Now, phases. is it 1 or 3 THAT what I need confirming. Well and whole calculations as a whole.

Thanks for answer.

I've been researching for past 2 months and I really need some help guys. Let me explain.

From what I understand ACTUAL draw from the wall by D3 using APW3++ Power supply and unit 220v line is around 930 WATTS. (Is this correct ? I am talking about REAL LIFE power draw here)
If this is not correct someone can please point out what is REAL LIFE power pull from the 220v line.

Let's say I am correct and APW3++ that is rated 1600 WATTS @ 220volt only pulls 930 WATTS can anyone tell me what type of service do I need to have for 10 units and for 50 units. separately.

I hear all type of thins. 1 Phase 300 amps, 3 phase 300 amps, 3 phase 100 amps. So what is it ? I got in touch with licensed electrician and provided spec from BITMAIN of APW3++ unit and D3 unit and guess what. I received almost 6 diffirent plans and types or lines I need. This is madness.

If possible, if anyone knows can you tell me in reality what do I need to run damn D3 units. 10 and 50 please, because I am about to give up, wait for unit to arrive, take KILL A WATT and measure myself because it seems people are clueless, even BITMAIN, no help at all.

P.S.

Video of D3 pulling 930WATTS @ 220v (it's in Geramany they don't have 110) is here: https://www.youtube.com/watch?v=-Z8v5BFxcmo

so if this video is correct, let's say round up WATTS to 1000 instead of 930 and then multiply it by 10 ? So 1000 WATTS x 10 units = 10000 WATTS of power @ 220v for 10x D3 units AKA: 45.454545455 AMPS. So it's around 50 AMPS for 10 units. IS that accurate ?

Let's say it is 45 AMPS. But is it 1 phase or 3 phase or As you can see I did research but now everything is a one giant confusion. IF anyone can confirm my calculations that'll be nice.

Thank you so much.
