Hi,

I would like to know if someone that have bought S4 miners had same problems as me.

I bought on black friday 32 units, first week working 3 PSU got waisted, after that some more till 7.

I replaced through RMA 6 of the 7 units, one unit was a fan problem, Bitmain told me they would send me a fan, but they did not. No answer from them.

Right now I have got, again, 6 more units with faulty PSU.

Since the first day I had got 4 boards with broken chips, but I couldn't make Bitmain to replace them, I am still under 90 days of warranty.

I had to pay for all the PSU shipment as well.

I opened all units to check them and I could see units full of dust near to be waisted.


Anyone with same problems?
