The Parisian club has now secured the prestigious trophy on 14 different times.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a straightforward win in the showdown between the French league champions and the Coupe de France winners after the French winger opened the net early on.
However, Marseille fired two times late to seize a shock lead. First, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a crucial equaliser in the final moments to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for PSG to seal a 4-1 shootout victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past 13 seasons.
