The Parisian club has now won the prestigious cup on fourteen different times.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be coasting towards a comfortable triumph in the showdown featuring the French league winners and the Coupe de France winners after Ousmane Dembele opened the net early on.
However, Marseille struck twice in the closing moments to seize a shock advantage. Initially, Mason Greenwood scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a crucial equaliser in the dying moments to force the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted successfully for Paris Saint-Germain to complete a 4-1 shootout victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the last thirteen seasons.
