Thise PSU units are too weak to start with, I recommend you get a stronger PSU for that amp.

The PSU shuts down automatically if there is a short or overcurrent condition.
First make sure whether this is the case, disconnect the amp and see what happens.

iv just noticed here that wen i turnd on the psu {wen it worked} the fan was going all the time . but it says that the fan is automatic meaning it turns on and off acording to the pempture of the cpu...could this spell a bad psu.

Nope, that's ok, I think.
Anyway, BW will replace it free of charge.
