Hello All!

I have over then last week or so now got the system to boot directly to a HDD
This is in a cradle with a USB connection plugged in to the Pi (3B+).

I want to streamline this a bit so all is in one box and have placed an order 
with
Aliexpress for :

Raspberry Pi 3 B+ HDD storage expansion board X830 3.5" Sata.
[ This allows a 3.5" drive sata drive to connect to a Pi via Sata -> USB 
connection. ]

Raspberry Pi X830 3.5" Sata storage board matching metal case/enclosure +

You need both lines of these links.

The problem seem to be what is needed for the Power adaptor as there are quite 
a few.
As the x830 shows one saying 14-40vdc, 3A then offfering a 19V 2A which 
needless to say only
has an EU or US plug using a DC Power Plug Size : 5.5*2.5mm.

In the questions section on the Metal case some one asks if a laptop adaptor 
giving 19V
3.42A is ok and they report yes.

So the question is what one as I feel that the basic one 19V 2A is under 
powered as I would
like it to run both the x830 / HDD and the pi.

The HDD does mention using 5V (0.5A) and 12V (0.7A).
The caddy is 12V at 2A but that is only running the caddy.

Any one have any recommendations as my brain is hurting ?

The docs on the X830 and for that matter the Pi is not detailed enough for me 
to work it out
or I am just getting too old,
