PSG has now secured the prestigious cup on fourteen different times.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable triumph in the showdown between the Ligue 1 champions and the Coupe de France holders after the French winger found the scoring early on.
Yet, the southern French side fired twice in the closing moments to seize a surprise lead. First, Mason Greenwood scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital equaliser in the final moments to send the contest into a deciding shootout. The Parisian shot-stopper 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 the young talent all converted successfully for PSG to seal a 4-1 shootout win.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the last 13 seasons.
