The Parisian club has now secured the prestigious trophy on 14 separate times.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown between the French league champions and the Coupe de France holders after the French winger found the scoring in the opening stages.
However, Marseille struck twice late to seize a shock lead. Initially, Mason Greenwood scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker snatched a vital equaliser in the final seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to complete a convincing penalty victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past 13 years.
