PSG has now won the prestigious trophy on fourteen different times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and secure a fourth straight French Super Cup title.
The Champions League holders seemed to be sailing towards a straightforward triumph in the match between the French league champions and the French Cup holders after the French winger found the net in the opening stages.
Yet, the southern French side fired two times in the closing moments to take a surprise lead. First, the English forward converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a crucial leveler in the final moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to complete a convincing penalty win.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this trophy for the 12th time in the past thirteen seasons.
