something on running two server supplies at lower wattage to run one miners boards separately as discussed earlier on If you run an ssr relay from pin 50(gnd) and 52(3.3v)or 54(5v) of the bbb to switch the second supply on when the controllers powered should you loose power to the controller it will shut down the second supply too or the second supply can fail and the controllers supply will still keep working as normal (you will still hash on the controllers supply board in this scenario) no more hashing while the fans are dead ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fprojects.wyliodrin.com%2Fwiki%2F_media%2Fpins_layout%2Fbeaglebone_pins_layout.png&t=665&c=5ghRj21CVznZbg) for ac cords http://www.ebay.com/itm/272248158722for server supply on/off pin jumpers http://www.ebay.com/itm/351340978967

Ok I will bet you do have at least one or two 220 outlets in your Canadian home.
If you have an electric oven it's 220 if you have a larger window Ac unit it's possibly 220 your electric water heater is also 220 but that one is most likely hard wired and if you have a electric washer and dryer they also are 220. Now all you have to do is go to Home Depot and get a 220 plug and make a plug that will fit into your existing 220 outlets.
Be careful 220 is very dangerous that's why we use 110 in America only half of us would still be alive if we used 220, no I'm not calling Americans dumb let's call it curiously stupid! ("Hey hold my beer and watch this") famous red neck last words... Antminer S9 - How to power in Canada? June 06, 2016, 08:20:56 PM Reply with quote #1 So the new, amazing Antminer S9 just came out... And I really want to buy it! But the S9 needs to be powered at 1375W, and with 9 PCI-e connectors (3/board). The recommended power supply is the APW3. The APW3 needs over 220V to run, but I live in Canada, and in Canada there is only 110V outlets. Currently I'm running 2 S5 antminers on one EVGA SuperNOVA 1300 G2, which has just the right number of connectors, which is 8. So now I'm either looking for a PSU that can do 1600W and has 9 PCI-e connectors and hope it will be enough, could use 2 PSUs to power one miner, or get a 110V -> 220V transformer and hope it doesn't blow any boards or circuits.
Please help me out you wonderful people Smiley

If you use the controller PSU to kick on the secondary, that violates Bitmain's recommendation to have the controller PSU always come on last. You'd have to momentary turn on the secondary PSU bypassing your mains switch, then let the controller PSU latch it on. If you want to play by Bitmain's recommendation anyway, so it's still the same problem noted in the first page comments.

ahh that puts a fork in under warranty machines i guess but bogus in my book since the controller gets it power from the hash board first thats connected to the supply so in all fairness the one boards powered before it anyway it only takes milliseconds for the ssr to turn on anyway ... to the naked eye they come on at the same time i doubt the board has time to even boot yet to poll the hash boards

I'm pretty sure the controller doesn't get power from the hashboards. The peripheral circuits of the hashboards (like the PIC and DPOT that set the string voltage) actually draw power from the controller, not the other way around. Worst case with a PSU common to hashboards and controller is they get powered at the same time.

no it definately does get the supply from the hash board using the small ribbon cable to the one board
remember the only connections from the psu are to the hash boards
they either step it down to 3.3v and 5v on each hash board or the bbb does it after it(12v) gets to the hashboard then to the bbb
from what i can see the top section opposite end of the small ribbon by the antminer board rev beside the pci-e plug is the voltage regulator step down circuit that provides the small ribbon the bbb.s power or host shield board , could be for the board itself for temp sensor power

There is a separate PCIe power socket on the fan/control breakout board that hosts the controller board.

ahh yeah i forgot were talking s9 lol i been thinking s5, my bad
doh
it would still get power at the exact time as the remaining pci-e cables from the same supply, that also supply the hash board
like i said it puts a fork in a warrantied wachine been so used to buying used stuff ..no waranty reminds self to check topic when i think of a solution next time before commenting

*shameless plug*
Another option for powering many units with limited panel space is going with a 240V (double breaker) 50A breaker, with appropriate cable run to a PDU and 4x 2880W PSU's. You could run 7x B3 S9's by code, possibly 8 in practice from that one circuit and not worry about powering on PSU's in the right order.

It's not a plug unless you point out your signature links ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) Which I endorse as a good solution, btw. 4*2880 or 6*2000 is my normal granularity as well, but I usually do a 60A breaker w/ 6GA supply lines - 4x2880 on a 50A breaker, even only running 7x Batch 3 S9s, could violate code if the voltage is much below 240V: On a DPS-2880 the at-the-wall will be closer to 1300 than 1275, and closer to 1350 once the 2880 fans are included; 7*1350 = 9.45kW 220V * 50A = 11kW; 9.45/11 = 86% With the cost differential so low for 50A/8GA vs 60A/6GA the latter has been my preference.

So I was just doing some browsing... If I went with the APW3-12-1600-B2 on 220V to power an S9... How many would I need? One has 5 6pin connectors. So you need two of those PSUs to power one S9 right?
Also I got confused,, the site said "Separate power supply to control board: there is one additional 6pin PCI-e connector on the IO board which must be connected to the PSU to get power.". So does that mean you need a third PSU just for the board??? Or do you just put your one left over cable into it?
What powersupply would you recommend? (Preferably under $250)

And if I went with the bitmain, I would need 2 of them to power 1 miner right?

1. Hire an electrician to install a 220V 208V (phase to phase) circuit. or 2. EVGA SuperNOVA 1600 power supply. See submodels with different effiencys (from gold to titanium) below. https://i.imgur.com/gDqem40.jpg this is your vest bet.

Ok I will bet you do have at least one or two 220 outlets in your Canadian home.
I support this from the 905 area code http://helium.powerprice.info/meterResidential L-L voltage is 240V :: 2 phase at 180 degrees. You have that to your Oven and Dryer plugs. If you buy a new house, it has another one in the garage for green vehicle charging stations.

+1, all my high voltage PSU's specify 200V as minimum, just like Bitmain. In regards to the PSU's I offer, I find the 2880Wbetter for 2x S9's than the DPS-4K. It puts the PSU at an efficient yet healthy state of load, very reliable, compact and easy to mount with 24" cables. Only challenge is noise and 200V AC input. The only difference 220V will make vs 240V is it will require slightly higher amperage (~9%) to provide the same wattage.

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.
