I wonder if anyone has an idea on this: I've opened up an old PC (P4) and found a strange device attached to one of the molex power connectors. It's basically a small black box 1 by 2" maybe. That was completely sealed.
After peeling off the enclosure (it was glued shut really tight) I've found that the insides are enclosed in some sort of plastic. It's like they poured the plastic into it as liquid and it set around the components fully enveloping them including the entire PCB. It is solid now, there is no way to get to the pcb to see the traces or components on it without causing major damage.
The only components that are not fully enclosed in the plastic mold, are two Thrystors. (BT151 and BT152).
What the hell could this be, and what is it's function?
It has no outputs, no other connections of any kind, it's only external connection is the molex power connector.
Since it is so secretive of it's insides my first thought was: CIA listening device :-D
My second thought was that it's some sort of overvoltage protection.
I'm no expert at electronics but I assume that would have to be connected in line with the components to function. Not parallel to them, right?
