However, I seriously doubt the PicoPSU DC Jack (Female 2.5mm 5.5mm) can handle > 5A. The one attached to the detachable harness looks really "cheap" compared to the ones I have from DigiKey.
For example, these from DigiKey can handle 5A and are constructed way better :
So the question is how safe is it to use the provided DC Jack on the picoPSU ?
Should we be concerned about exceeding the 5A rating on the DC Jack ?

A 120W 12V adapter would be 10A so that would exceed the spec for the jack and possibly create a hazard (melt? fire?). If I can find it I'll post it.
Found it. "Input current should not exceed 8A. For current higher loads, we suggest using a 2x2 mini-FIT JR as an input connector." It's actually in the 150W picoPSU manual and it's talking about the wiring harness with the 2.5mm*5.5mm barrel jack. So, maybe it's 8A, not 8.5A which I'd assumed since the largest single pin AC adapter they sell is 102W.
