PSG has now claimed the prestigious cup on fourteen separate times.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward win in the match between the French league champions and the Coupe de France holders after the French winger opened the net in the opening stages.
However, the southern French side struck twice in the closing moments to seize a shock advantage. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a vital leveler in the final seconds to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to complete a convincing penalty win.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the last thirteen seasons.
