Me see 5 wires.  Screengrabs is from 1st set of splitters that come up in the link I sent. [IMAGE] I only nit picked about "...data power..." a little is because data and power are separate cables.
I have a Optiplex 9020. It has a 3.5  HDD as the main drive.  I'm going to get a 2.5 inch SSD drive and use that as the main boot drive and the HDD as a storage drive.  I need a data power splitter cable but which do I need. Does it need to be Dell genuine or is after market UK.  I note the existing cable has five leads but ones I'm finding on Google have four. Many thanks
