PSG has now secured 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 capture a fourth straight Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable win in the showdown featuring the Ligue 1 winners and the Coupe de France holders after the French winger found the net early on.
Yet, Marseille fired twice late to seize a shock advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a vital equaliser in the final seconds to force the contest into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the hero, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to complete a convincing shootout win.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the past thirteen seasons.
