The Parisian club has now claimed the season-opening trophy on fourteen separate times.
Paris Saint-Germain needed 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 European champions appeared to be sailing towards a straightforward win in the match featuring the French league winners and the Coupe de France holders after the French winger opened the scoring in the opening stages.
However, the southern French side struck two times in the closing moments to seize a surprise lead. First, the English forward converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a crucial leveler in the final moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving decisive attempts from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for PSG to seal a 4-1 shootout victory.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the last thirteen years.
