I'm looking at getting a 200W DC-DC power supply (here) for an HTPC. What I am confused about is do I need an AC-DC external power adapter that has an output of 200W in order to get 200W out of the DC-DC?
if you want to run it from AC (mains power) then you will need a AC to DC converter of the same wattage in order for it to function.
Thanks guys! Edit: Do you know where I can find a 200W or higher AC-DC power adapter? The highest I can find is 150W.
