The Parisian club has now secured the season-opening cup on fourteen different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect spot-kick decider to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The European champions seemed to be coasting towards a straightforward triumph in the showdown featuring the French league champions and the French Cup holders after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side fired twice in the closing moments to seize a surprise advantage. Initially, the English forward scored 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 snatched a vital equaliser in the final seconds to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a 4-1 shootout win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the last 13 years.
