Reputable S15 PSU Repair or Advice

[weedle622]

We have 300 of the APW8_16.32V-20.04V PSU's that are dead, and Bitmain isn't selling them anymore.

30% of our S15 PSU's have died (or reboot after a few seconds) which seems extremely high compared to our other miners.

Does anyone have experience fixing the most common issues with S15 PSU's? We don't have the experience on site to do more advanced repairs.

Or has anyone worked with a reputable repair shop I should reach out to.

Thanks for any help

You should learn basic electronics first if you are going to repair PSU.

You can try to buy on Amazon or Aliexpress the only problem ordering PSU on both Amazon and Aliexpress is a bit expensive compared to Chinese shops on Alibaba.

Look at this on Alibaba

Or if you still looking for a repair shop I think, try to contact zeusBTC maybe they are near your area.

Have you tried to clean those PSUs? a very common problem is that the PSU gets hot and shutdown.

If the other miners are S9s or the like then it isn't a fair comparison, the APW8 is very sensitive to voltage while APW3 and APW7 are not, so this could all be caused by the wrong voltage input you feeding them with.
