The Parisian club has now claimed the season-opening cup on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in the Gulf and secure a fourth straight French Super Cup victory.
The European champions seemed to be coasting towards a comfortable triumph in the showdown between the French league champions and the French Cup holders after the French winger found the scoring in the opening stages.
Yet, the southern French side struck two times late to take a surprise lead. First, the English forward converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a crucial leveler in the final moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 penalty win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past 13 years.
