ATX PSU to 2.5 or 2.1/5.5mm 12V coaxial plug power cables

[iceman14304]

Im looking for a molex to barrel plug connector and id like to pm Cablez and ask if he makes one similar to that however I do not have the permission to PM, can anyone tell me where I can find a cable such as this? Does it even exist? Im looking to power a lighting kit that runs on a laptop PSU and id like to have it plugged directly into my PC PSU instead.
