PSG has now secured the season-opening cup on fourteen different occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight French Super Cup title.
The European champions appeared to be coasting towards a straightforward triumph in the showdown between the French league winners and the French Cup holders after Ousmane Dembele found the net in the opening stages.
However, Marseille struck two times in the closing moments to seize a shock advantage. Initially, the English forward converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial equaliser in the final seconds to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a 4-1 shootout victory.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this competition for the 12th time in the last thirteen seasons.
