The Parisian club has now secured the season-opening cup on 14 different times.
The Parisian giants required a stoppage-time equaliser followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and capture a fourth straight French Super Cup victory.
The European champions appeared to be coasting towards a comfortable triumph in the match between the French league winners and the French Cup holders after the French winger opened the net in the opening stages.
However, Marseille fired two times in the closing moments to take a shock lead. Initially, the English forward scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial leveler in the dying seconds to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to seal a 4-1 penalty victory.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the last thirteen years.
