The Parisian club has now claimed the prestigious trophy on 14 separate times.
The Parisian giants required a stoppage-time leveler followed by a perfect spot-kick decider to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward win in the match between the French league winners and the Coupe de France winners after the French winger found the scoring in the opening stages.
Yet, the southern French side struck two times in the closing moments to seize a shock lead. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker snatched a crucial equaliser in the dying seconds to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a 4-1 shootout victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the past 13 years.
