PSG has now secured the prestigious trophy on 14 separate times.
The Parisian giants required a dramatic leveler followed by a perfect spot-kick decider to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward triumph in the showdown between the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side struck two times in the closing moments to take a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of events, the Portuguese striker snatched a crucial equaliser in the final seconds to force the contest into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for PSG to complete a 4-1 penalty win.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the past thirteen years.
