problem with a bitmain power supply (APW3-12-1600-B2)

[pupok]

hello, before i made my S9 purchase i bought some S7 just to test everything and start learning

the s7 came with a  APW3-12-1600-B2 power supply

the thing is its acting weird

it does turn on and it does power on the antminer, but the antminer suddenly restart after , i know its the power supply because i tried other Psu with the antminer and its working perfectly

my question is

is there something i can do to try to fix it?

Well do you have 240 volts?


You said you used anther psu what was it?


I assume you have 240volts.

The s-7 uses less power then the s-9

Maybe the psu is short power.


What psu does work for you?

i have one APW3-12-1600-B2 (the one giving me problems after 8 months of use)
and i have several of this one https://shop.bitmain.com/productDetail.htm?pid=00020160905064759862LCcn24oJ0685

the one with problem is acting like is running out of power or something i tried other wall holes and still

If the miner works fine with another PSU then yes the PSU is failing.

Since I take it you do not even have a voltmeter to verify what the voltage out of the PSU is the following must be said:
Unless you work with building/repairing power electronics and know what you are doing DO NOT OPEN THE CASE OR ATTEMPT TO REPAIR IT YOURSELF!! Lethal voltages are present along with possible serious arc-flash hazard.
