The Parisian club has now won the prestigious trophy on 14 different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be coasting towards a straightforward triumph in the showdown featuring the French league winners and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
Yet, Marseille struck twice late to take a shock advantage. First, Mason Greenwood converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a vital leveler in the final seconds to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to seal a 4-1 penalty win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the last thirteen seasons.
