PSG has now won the prestigious cup on fourteen separate occasions.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable win in the showdown between the Ligue 1 champions and the French Cup winners after the French winger opened the scoring in the opening stages.
Yet, the southern French side struck two times in the closing moments to seize a shock advantage. Initially, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital equaliser in the final moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to complete a convincing shootout victory.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this trophy for the twelfth time in the past thirteen seasons.
