The thread took an interesting and relevant turn to replacement AC adapters. I will copy some of this info to a new section in the OP.
The powerbricks that drive D-Links are rather warm to the touch, so I pointer one of the fans to blow over them. If the worst comes to worst, and they start dying, I have the following contingency plan:
I have 3 old PSUs lying around.
Two ATX ones, where you have to short the green wire for them to start. Their 5V rails are rated 28A and 30A respectively.
I also have one AT PSU from the olden 486 days, where the PSU is turned on my the means of a physical switch (which was operated through a series of levers in the case)
This has an 18A 5V rail.
My plan is to connect the cables from any eventual failed powerbrick to the 5V output on the Molex connectors, observing polarity. It works for motherboards, harddisks and all that stuff that gets connected directly to the PSU, so it should work for a hub. Or am I wrong? SolidBitShop, that's a question for you.
Another note. When people start connecting those barrel connectors, pay attention to polarity that the hub expects. So have (+) on the inner connector, other can have (-).
