PSG has now won the season-opening trophy on fourteen separate occasions.
The Parisian giants needed a stoppage-time equaliser followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward triumph in the showdown between the French league champions and the Coupe de France holders after the French winger opened the scoring early on.
Yet, the southern French side fired two times in the closing moments to take a surprise advantage. Initially, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker grabbed a crucial leveler in the dying seconds to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving decisive kicks from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for PSG to complete a 4-1 shootout victory.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this competition for the twelfth time in the last 13 seasons.
