The Parisian club has now secured the season-opening cup on fourteen different occasions.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and capture a fourth straight French Super Cup victory.
The Champions League holders appeared to be coasting towards a straightforward win in the showdown between the Ligue 1 champions and the Coupe de France holders after the French winger found the net in the opening stages.
Yet, Marseille struck two times late to take a shock lead. First, the English forward scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a crucial equaliser in the dying moments to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
