PSG has now claimed the prestigious trophy on fourteen different times.
The Parisian giants needed a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a comfortable win 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 struck two times in the closing moments to take a surprise advantage. Initially, Mason Greenwood scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital leveler in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, saving crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to seal a convincing shootout win.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this trophy for the 12th time in the past thirteen years.
