Hi,
Just want to ask a question that is not clear on everything that I have read. If you don't switch off the external power what do you take the risk for? Could you burn something or the card will just continue to work (spin the fan) after you turn off the Mac Pro? Where is the dangerous part?
Thanks!
It's not so much dangerous as wasteful.
If you connect any Mac Power lead to the aux supply's sense input, it will power up and down automatically with the Mac.
