I am trying to ressurect an Alien DSD105 DVR I have obtained, but it has no power supply. Phil at SystemQ has been trying to get one for me, but no luck so far. The problem is that it uses an unusual 4-pin connector from a 12V/60W external power 'brick' so a standard co-axial PSU won't do.

Does anyone know what the pin-outs are for this connector? (or perhaps know of a power supply lying unused)

Picture from the manual attached showing connector (number 13)

Any help would be much appreciated.

One possible way to figure out the pins is to meter them out to known points within the DVR. For example you know the ground pin on the HDD connector, that may find you the common pins, likewise there is a 12v pin on the HDD connector and so forth.

Thanks for that - I hadn't considered using the Molex connector.

My concern was that it was a dual voltage power supply and it would be tricky to identify which pin supplied what, however, after stripping the circuit board out it was very obvious that it is in fact a single 12V supply, just doubling up the pins for supply and earth.

Thanks again for your helpful comments.
