Yeah thats a possible issue.
But now Im wondering exactly how does a working a1 work since you plug it in? I forgot their normal behaviour!:(
should it start with very low speed (big)fans? didnt they start with maximum speed and then turn down?
the 4 LEDs on the control board representing 4 hash boards dont do anyyy blinking until the pool is connected??
and the mining program on the control page doesnt show up until the pool is connected?
Im afraid the problem be the psu's 😢
could anyone having A1 answer me🤕
