I am looking to use the Penta SATA Hat on a Rock Pi 4A+ and I have a couple of questions.
I want to power five 3.5" drives in this case:
This case is also pictured on the wiki but you cannot see the rear side on the wiki:
On the wiki it says I can power 3.5" HDDs with a 12V/6A DC barrel jack adapter. I would strongly prefer this over using an ATX supply. But on the allnetchina link above, you can see the rear of the 5 drive enclosure, and there are 2 x Molex connectors and the description says you need an ATX PSU.
So I am not sure how to have an enclosure where I do not also need an ATX PSU. The wiki says I can power 3.5" drives with the DC barrel jack, but the 5 bay enclosure does not seem to support powering the drives this way. How can I power five 3.5" drives with just the DC barrel jack? Will the Rock Pi 4A+ also be powered through this cable when plugged in, or only the Penta Hat + drives?
