PSG has now won the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and secure a fourth straight French Super Cup victory.
The European champions appeared to be coasting towards a straightforward win in the match between the French league champions and the French Cup winners after Ousmane Dembele found the net in the opening stages.
However, Marseille fired twice in the closing moments to take a surprise advantage. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital leveler in the final moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to complete a 4-1 shootout win.
The record winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last 13 years.
