The Parisian club has now won the prestigious trophy on fourteen separate occasions.
The Parisian giants required a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable triumph in the showdown between the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
However, Marseille struck two times in the closing moments to take a shock lead. Initially, 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 turn of events, the Portuguese striker snatched a crucial equaliser in the dying seconds to force the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for PSG to seal a convincing shootout win.
The record winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the last 13 years.
