The Mac Plus power supply has its flakinesses, but it's not nearly as
bad as its reputation suggests.  Most "power supply failures" are
actually video failures, but since the video circuitry is on the power
supply board, the power supply gets blamed.  Even if the 1MB SIMMs used
a little more power, which they don't, the supply has some capacity in
reserve.

This will use significantly more power, but most such setups come with
an auxiliary power supply to run the extra logic.
