PSG has now claimed the season-opening trophy on fourteen separate occasions.
The Parisian giants required a dramatic leveler followed by a perfect penalty shootout to overcome their arch-rivals in the Gulf and secure a fourth straight French Super Cup title.
The Champions League holders appeared to be sailing towards a comfortable win in the showdown featuring the French league winners and the Coupe de France winners after the French winger found the net in the opening stages.
Yet, Marseille fired twice late to take a surprise lead. First, the English forward scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a crucial equaliser in the final seconds to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 penalty win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this competition for the 12th time in the last 13 years.
