So, if you use one of those lightweight 4.5 A PSUs, I guess you can safely extract 2 A from the floppy port if necessary. |

There are EMI components in the power lines for the external disk drive which would limit the amount of current that can be drawn safely. The Commodore documentation lists 540mA as the limit for continuous use, or 870mA as a surge. So while it's probably possible to draw more than that, I would advise against it.
