The Parisian club has now secured the season-opening cup on fourteen separate times.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a fourth straight French Super Cup title.
The European champions appeared to be coasting towards a straightforward triumph in the match featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele found the scoring early on.
However, Marseille struck twice late to seize a surprise lead. First, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of events, the Portuguese striker snatched a crucial leveler in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping decisive attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for PSG to seal a 4-1 shootout win.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this trophy for the 12th time in the past 13 seasons.
