PSG has now secured the season-opening trophy on fourteen different times.
The Parisian giants required a dramatic leveler followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight French Super Cup title.
The European champions seemed to be sailing towards a comfortable triumph in the match featuring the French league champions and the Coupe de France holders after Ousmane Dembele found the net early on.
However, Marseille fired twice late to seize a shock advantage. First, the English forward converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial leveler in the final seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for PSG to complete a convincing shootout win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this trophy for the twelfth time in the past thirteen seasons.
