I recieve my s4 b2 today, but its Dead On Arrival, I think the PSU is dead. My first disappointment after I purchase alot of bitmain miner.
Send RMA request lets how it goes...Btw can I use my normal PSU to run the machine?
Thanks

My first and almost certainly the last S4,
worked with EVGA G2 1300W and waited for new PSU over a week .
Max 1200W , Frequency 181,25M GH/S(avg) 1800 , at pool 1630

sorry to hear that, we had been in contact with the PSU supplier and the good PSU actually had been shipped out in succession these days.
please contact info@bitmaintech.com or ting.shao@bitmaintech.com about this. We will track it in the system and keep you updated.
