I have a 950W T5820 that I want to add a Nvidia Titan card to in addition to the original Quadro which requires additional power connectors.  The required cable has a male 10-pin connector on one end and 6 and 8-pin(6+2) on the other end (according to tech support) . Tech support gave me their part number as P94J9.  The spare parts people however can't find such a cable.  I see on ebay there are very similar looking cables for HP systems and if the 10-pin connector is standard perhaps one might work.

Does anyone know if these cables are available from Dell?  I'm in Australia.

Thanks.
