PSG has now won the season-opening trophy on fourteen different occasions.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be sailing towards a comfortable triumph in the showdown between the French league winners and the Coupe de France holders after the French winger opened the scoring early on.
Yet, Marseille fired twice in the closing moments to take a shock advantage. Initially, the English forward converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a crucial equaliser in the final seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to seal a 4-1 shootout victory.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the last 13 seasons.
