BITMAIN AntMiner APW3-12-1600 PSU Series

[Sweminer777]

So if it runs 11.5v or 12.6 it wont make any changes it will just stay always at 4050 then in other words

The Buck Converter in Batches 6,8 & 9 will regulate the voltage to whatever Bitmain has set it to. Not sure what you mean by 4050?

I just got an antminer psu, so i am guessing its not on the max volt i think th ey come 11.9 ?  .

I meant if i regulate up the psu to 12.6 it won't matter as the hash wont go upp ?.

Correct, hash will only be increased by pushing up the frequency, but need to check HW errors & temperatures.

Yeah, i will try to max the volt, and ill come back , as at it is sitting, if i go 606, my hash drops to half .

but feeders bitmain what are they?
bronze, gold, platinum?

Ok so i  was turning the knob but it dont have a stop, it go all the way around.

*i noticed that the Screw is not totally ciruclar.

Were should i place the " LINE" that is there.

I dont have a meter on me right now, and its to late to pick one up.

I would put it in the middle of it's travel. The "Flat" needs to be aligned with the 2 pins at the ends of the pot as opposed to the single pin opposite them. If in doubt wait until you have a meter to measure the voltage.

Upp like the red line is what you mean right , if i understand you correcct?

At this moment it is at the Purple mark, and i tried 612, and is actually more stable than before and less errors.

Ill wait for your response to disamble again


On the side atm it is running abit colder aswel less 5c on the temps . hmmm

I cannot positively confirm as I do not have one here to check. I would wait until you have a meter and set it properly rather than guessing.

do not buy this crap unless you have really good fire insurance.

totally uncalled for useless comment. Thanks for contributing to an otherwise decent discussion

Did one catch fire recently?

Hello everyone! I registered to ask this question because Bitmaintech lets me wait more than 40 days for an answer to my support ticket....

This is my question: How many Antminer S7 units can I connect to one unit of this PSU? Physically it seems that you could connect at least 2 pieces of S7 to one PSU. Does this really work or is it unwise (overloading, fire hazard etc...)?

Thanks in advance for your answers!

Bitmain clearly says that ONE APW3-12-1600 PSU for ONE ANTMINER S7. And there is no extra PCI-E connectors.

I have to ask what is your voltage in your place to mine.

You need 205 voltage or higher to use this psu.

where do you live?  as usa is 120 voltage.

Yup only one S7 can be powered by a APW3-12-1600 PSU. There just enough connectors and power capacity for a single S7.

Didn't they come with 12 at one point?



Image in the first post says 6 pairs of 6.

[philipma1957]

Typo IIRC

I THINK IT WAS ALWAYS 10

So more false advertising that they don't want to correct.  Gotcha!

[NotFuzzyWarm]

The first 2 I got from Bitmain have 12 PCIe connectors. Also no provision for DC on/off unless there is a header inside. Now they all come with 10 PCIe and a DC on/off pigtail  plug w/jumper on it.
