PSG has now won the season-opening cup on fourteen separate times.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and capture a fourth straight French Super Cup title.
The Champions League holders appeared to be sailing towards a straightforward win in the match between the French league champions and the French Cup holders after the French winger found the net in the opening stages.
Yet, Marseille fired two times in the closing moments to seize a shock lead. Initially, the English forward scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a crucial leveler in the final seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving decisive attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all converted with composure for Paris Saint-Germain to seal a convincing shootout win.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the past 13 seasons.
