PSG has now won the season-opening trophy on fourteen separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and capture a fourth straight French Super Cup title.
The European champions appeared to be coasting towards a comfortable triumph in the match between the French league winners and the French Cup holders after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side fired twice late to seize a surprise lead. Initially, Mason Greenwood 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 fortune, Goncalo Ramos grabbed a crucial leveler in the dying seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to seal a 4-1 shootout victory.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the past thirteen seasons.
