PSG has now won the season-opening trophy on 14 different occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect spot-kick decider to overcome their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable win in the match between the Ligue 1 champions and the Coupe de France winners after the French winger found the scoring early on.
However, the southern French side fired two times late to take a surprise lead. First, the English forward converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos snatched a vital leveler in the final moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a convincing shootout victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last 13 years.
