Currently I have one S9(13.5) running on Kano and I have room for at least one more S9 by my calculations . (I briefly looked at the Dragonmint 16T but the extra cost for the power doesn't seem worth it to me) I do wonder like most, if something will be released soon that would make me wish I waited a hair longer but I'm not a patient person Wink

I'm not the best with technical electrical conversions so please anyone if you are, let me know!

I had a dedicated 220 outlet (12 gauge wire) ran by an electrician and he added a 20amp breaker. I think my current S9 is roughly 1400 watts which in turn translates to 7 amps. He said the wire is good for up to 25amps so we could swap the breaker out if needed. I'm pretty sure I can easily add at least one more miner to my stable for Kano.

The more efficient the power supply you use, the higher chance of you being able to run 3 on 220V 20A is.

First - are you sure its 220V? Current electrical national electrical code for single phase is 120V/240V I always see 235-240V at the wall. Three phase or really old electrical co-ops will/may give other, lower "2 leg" voltages. It makes a difference in your case:

Lower voltage:
1400W / 220V = 6.36A then (3 x 6.36) + 2.0(10% of breaker size as safety factor) = 21.08 amps )-:

Higher voltage:
1400W / 240V = 5.83A then (3 x 5.83) + 2.0(10% of breaker size as safety factor) = 19.49 amps (-:

As you can tell - you could run three WITHOUT changing the breaker if it is 240.

Couple of caveats:
I am not a electrician
Only you and your electrician know if this actually makes sense for your circumstance.
If you upgrade to 25AMP, make sure your plug is rated for 25Amp too.

Hope this helps!
