The Parisian club has now won the prestigious trophy on 14 different times.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the showdown featuring the French league winners and the Coupe de France holders after the French winger opened the scoring in the opening stages.
However, Marseille struck twice late to take a surprise lead. First, Mason Greenwood converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a vital equaliser in the final moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this competition for the twelfth time in the past 13 seasons.
