Antminer S9 on 110v with APW3++

[tuaris]

I was expecting the S9 to arrive in Jan 2018 but it arrived much sooner (yay!  ).  
Problem is I'm not prepared yet to power it at 220v as is suggested for the APW3++ power supply.  For the moment I only have 110v.

If I were to attempt to power it using 110v would it result in damage to the miner/power supply?  Or would it simply run at a less efficient rate?

Dont do it, you will have problems. Even if you get it to start hashing on the PSU it will be overloading the power supply very badly. What you can do for now is hook it up to 2 of the hash boards and the controller and run it on 2 until you get the proper outlet setup for it.

It may work, but you can also burn your power supply, with some extra bad luck your miner could go down with it. The failure rate of these machines is already high (meaning they are pretty low quality) so I wouldn't push it beyond specs. If you really can't wait for your 220v installation you could buy a 1600W 110V PSU (and then resell it, return it, whatever).
Edit: And yes, use only two boards is an option too, that's how I'm running mine but just because one board lasted only 4 days...

power  two boards  and the controller.


do not power the center board.

you will  get 9th instead of 13.5 th the psu can do that.

Great, thanks all.
One last quick question.  The included documentation says the total current at the wall for an S9 is 20A.  Is that correct, it seems a bit high?  Wouldn't it be 14A?  Or am I missing something (ie. power factor is not 1)?

It pulls around 6.5-7 amp at 220 so around 14 on 110 is right. If its pulling 20 amps id say grab a fire extinguisher lol

yall are wrong. the power supply does both input voltages plug it into 110 it runs fine. this is from bitmains page.
2. The APW3++ can deliver a maximum power of only 1200W if it is connected to a 110V mains power supply. To obtain the rated power of 1600W, the APW3++ must be connected to a 220-240V mains power supply. Please check the mains power supply that is the standard in your region before ordering.  you can go to lowes and buy a 6-20R receptacle and 6-20P plug if you want to wire it up for 220v its smaller than a dryer plug in.
 I have been told that it will most of the times still hash at 13.5 ths even on 110v.
this is out of the s9 manual.
 The miner does not contain a DC/DC converter; therefore, higher input voltage will cause higher
Mining efficiency .

No, these guys are right it is you who's wrong. While yes, the PSU will run off 110v (the PSU is pretty much a multi purpose PSU) it will not provide adequate power to run an S9. If the S9 does power up it will be at a lower hashrate. Just read the forum and you'll find plenty of people who's S9s wont even start with the APW3++ on 110v.

I bolded the part about you having been told, so you haven't actually done what you are recommending?

You are too excited to start mining, just sit and relax a sec, or you will damage or shorten the life of your miner.

Just wait for your electrician to come in and install a 220V connection for you.
