While the Swans played in bursts, the Power made the most of their opportunities to break open the game in the second quarter and maintain the difference to win 4.16.11 (143) to 1.10.9 (78).
The only souring note for the Power was the first-quarter report of forward Daniel Motlop for a bump on Swan Jesse White.
The big youngster was caught high by Motlop and left dazed, but recovered to play out the game. It was a different story for his teammate Ryan Brabazon, who was stretchered off in the third term with concussion.
The Swans were without Barry Hall, Michael O'Loughlin, Leo Barry, Lewis Roberts-Thomson, Henry Playfair and Patrick Veszpremi, with Canadian experiment Mike Pyke and ruck prospect Jake Orreal making quiet debuts.
For the almost full-strength Power, Warren Tredrea looked fit and strong to slot three goals, while his successor as captain Domenic Cassisi put in an impressive 19-possession performance.
Rookie Wade Thompson was a highlight for the Power with an exciting three goals, while Swan Rhyce Shaw did well for his new side with some dash from defence.
The Power started slowly with the Swans controlling the first 10 minutes of the game.
The Swans drew first blood with Craig Bolton booting a supergoal from an Adam Goodes handpass, before elevated rookie Matt O'Dwyer followed up with a six-pointer.
The Power recovered to round out the term with four straight – the first of which a supergoal from Danyle Pearce.
Thompson kicked the last goal of the quarter – and his first in AFL football – to give the Power an 11-point lead at the first break.
The Swans started the second term well and snared the first two goals through Mark McVeigh and Goodes, which briefly gave them the lead.
However, it was the last time the red and white would hold the advantage, with the Power piling on two supergoals and five six-pointers throughout the rest of the term.
Daniel Motlop snared two that opened the floodgates, before former Tiger Danny Meyer ran and delivered from outside the 50m arc for a super-goal.
Warren Tredrea was gifted another at the 12-minute mark when White forgot the NAB Cup ruling that dictates play on for backward kicks and was caught.
Josh Carr missed his chance to kick his first Power goal since 2004, but Justin Westhoff and Brett Ebert added majors, and Tom Logan another nine pointer, to give Port Adelaide a 48-point buffer heading into the second half.
Jude Bolton - wearing a helmet after a first-quarter clash left him with a cut head - opened the third with a goal before the Power kicked into gear to add three to its tally.
However, a strong finish to the quarter with Mark McVeigh, Ryan O'Keefe and Darren Jolly figuring on the scoreboard got the Swans within 36 points.
Ruckman Brendon Lade put an end to that run with a supergoal as the siren neared, which left the Swans with a 46-point gap to chase.
The Swans started the final term well but were again blown away once the Power got a run on, with the final difference the biggest NAB Cup margin so far this year.
Port Adelaide now faces Geelong next weekend while the Swans will play the Demons in Melbourne.
