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 mine alt coins with https://simplemining.net...
I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

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.
