Antminer S9 - How to power in Canada?

[fanatic26]

You all realize that as long as you arent running firmware from last year your board wont blow up if its powered and idle right? Running two power supplies is no big deal, i had to run a good 100 S7s with multiple power supplies and never had a problem. Its no different than the beagle crashing, the boards just sit there idle.

P.S. Dont listen to all the people that say upgrading firmware is dangerous. As long as you have half a brain and use the proper firmware for your system it will work just fine.

Hey guys I read the posts here and am trying to piece together myself how to rig up my first S9 & APW3+ PSU. I also live in Canada, and have a 240 V Nema 6-30 straight blade receptacle in my garage (same kind used for ovens / washer etc).

I'm trying to figure out how to best adapt this receptacle to plug in the APW3+ PSU with the standard C13 power cord.

Any idea's on appropriate adapters? I would prefer not to have to rip out the receptacle, but I will if I have to.

Go to home depot or whoever and buy a male 6-30 plug. Take normal C13 cable, cut off the 5-15 (normal 110v) plug and wire cord to the 6-30 plug. Works but take care to use the heaviest gauge computer cord you can find since you are using a 30A outlet...

Best/safest way is to search Amazon for a 4-outlet 208/240v PDU that can plug into the 6-30 and break out into 4 outlets each protected for lower current. While there also get a couple IEC-C13 male/female cords as that is what the PDU outlet sockets will be.

Fun discussions.
As an electrician I know all the sneaky ways to find 220 in a home, lol
And have helped people setup for such things in the past.

Please note, that even the EVGA etc. PSU's that run at 120, WILL all run at 208+ and are actually slightly more efficient, and draw less amps over the wiring so is safer.
I always recommend 208 if it's even remotely possible. Regardless of PSU.

You CAN... wire a standard 20amp 120v plug to output 208, which saves money as you can than use the stock high quality PSU power cable that comes witht he EVGA.

Just note that that isn't code, and if you forget and plug other items into said plug, they may go poof.

Although a surprisingly large amount of stuff can run on both 120 and 208.

Pixel I'm also in Manitoba, feel free to give me a shout if you need anything.

Hey guys so i notice noone has poster here in a while but from what i gather from reading these posts i can run a EVGA 1600 PSU on 120V to power a single S9 without having to mess with my service?

But if i did have to mess with the service i would have to run a double 15A Breaker on 120V line to power the AP3 psu for the antminer S9?

The is no such thing as "double 15A Breaker on 120V line".
When a 2-pole breaker is installed in your panel it provides 220VAC - not 120v. Incoming single phase power to a house comes in as a 220v service with a Neutral.

Go across the 2 lines you get 220VAC, go across either line and Neutral you get the 120V...

I see what you mean, 3 phase 220 then, which would also require bigger wire i would assume? and how many of the antminer S9's could i plug into each receptacle ?

3-phase? No, residential power in North America is single-phase power changed to split-phase 220v (110V-Neut-110V) by the Utility transformers on the poles. It is still just 1 phase, just that the pole transformer has a center tap providing the Neutral (which is also tied to ground at the panel) and that is what feeds the house. ref https://en.wikipedia.org/wiki/Split-phase_electric_power

Three-phase is entirely different and will either be 3 hot lines with a Neutral (Wye) or 2 hot lines with the 3rd also tied to ground  - no Neutral per-se (grounded Delta).

5 pages and NO CLEAR STRAIGHT ANSWER...

I have 4 S9's...due any day..and 4 more due in oct..

I will use the recommended PSU...APW3++.....

I understand why and agree intend to use 220V..BUT WHAT AMPERAGE for the breakers...
standard here is 220v/30amp...
There is no way in hell a 1600watt PSU needs 30 amps

(I previously ran a GPU farm with each rig having it's own 110v/20amp...no problems
But this is a whole new ball game...

[NotFuzzyWarm]

sigh... A simple Google search would tell you that:
Amps = watts/volts.
For safety margin add 20% to the answer.

[mustangy]

easy basic calculation
no clear answer
1400 w (almost a s9)
at 110v 12.7amp
at 220v 6.36amp
so you can figure out the rest

There are no clear answers because everyone has a different setup! What other items are on the same circuit, what is the gauge of wire being used, etc? There are a myriad of questions that need to be answered before one can make an informed recommendation. I would suggest consulting a local electrician to examine your setup and make sure you are running things safely. My setup is as follows, but that does not mean it will work for you or that it is even applicable to your situation.

I have a dedicated 100 amp sub panel with a 35 amp breaker. From the breaker I used 8 gauge romex copper wire to run to the power outlet that feeds the 4 port PDU. Electricians have told me that generally speaking the real world capacity of electrical equipment should be 80% of what it says on paper. Using that formula I theoretically should be able to have 6,720 watts worth of a 240v equipment running across that line with no problem. Now, im not an electrician and I could have made a mistake, but this setup has been working for me for the better part of a year. Nothing has melted or caught fire yet.

If you are running all of your S9's on the same circuit you will need a different breaker than if you plan on running them all on separate circuits. If you ran each s9 on a separate 240v circuit then a 10amp breaker should be sufficient for your needs.

thanks a lot
fusion0389
would you please add images of
which pdu
and what 8 gauges cable with setup
i m doing almost same setup 40amp braker per 4 antminer s9 10amp each 4 port pdu
and as you said 8 awg cable is look like enough for 4 miners at 208v
would you mind add pictures of those or dm please thanks again you save a lot time now my electrican is clear about what to do.

I am new to mining Just ordered my 3 S9's for new batch:

Well I have Electric dryer outlet ( 220~240 volt / 30 amp breaker - 4 prong Socket )
I want to run at least 2 S9's on it
Should I order this

and connect my PSU' to it ?

Or

I need step down transformer which is around 5000 watt to 110v output

and connect my PSU's to output socket ?

Which one is the better option ?

If some one has better idea Please suggest me.
