12 volt plug-in PSUs

AncientMariner
A friend has just asked me a question re 12 volt plug-in PSUs where the answer seems obvious, but then again?


His question is that as he has a multitude of 12 volt PSU's supplying numerous devices, is there any problem in using a suitably rated 12 volt PSU with a multi-way splitter cable such as those sold on eBay,  subject of course that all have the same polarity and 2.1 5.5 mm connectors?  My unsure concerns being whether there is a risk of difference voltages between exposed metal work (if any) on the connected device. Also the overall efficiency depending upon how many devices are connected.

    If you are feeding severable items of a larger overall system then ensure all PSU's are fed from the same phase andake sure the negatives are commoned. Other than that I think you're going to be fine.
