I was able to do a search and could not find a suitable adapter from Dell themselves in our range. Since manufacturers like Dell like to use their own motherboards and connectors, I recommend contacting the manufacturer directly to see if they have a special adapter for your application. Otherwise we have 8pin to SATA power adapters such as the following:
