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
