The Parisian club has now claimed the prestigious cup on fourteen separate times.
The Parisian giants needed a stoppage-time leveler followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The Champions League holders appeared to be coasting towards a comfortable win in the match featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele found the scoring early on.
Yet, Marseille fired two times late to seize a shock lead. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker snatched a crucial leveler in the final moments to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for PSG to complete a convincing penalty win.
The record winners PSG, who met 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 last 13 seasons.
