PSG has now won the season-opening cup on fourteen separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown between the French league champions and the French Cup holders after the French winger found the net early on.
However, Marseille fired two times in the closing moments to take a surprise lead. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital leveler in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to seal a 4-1 penalty victory.
The record champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the past 13 years.
