PSG has now secured the prestigious trophy on fourteen separate occasions.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to get past their arch-rivals 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 match featuring the Ligue 1 champions and the Coupe de France winners after the French winger opened the scoring early on.
Yet, Marseille fired twice late to take a surprise lead. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a crucial equaliser in the final moments to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, stopping decisive kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for PSG to seal a 4-1 shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the past 13 seasons.
