PSG has now won the prestigious trophy on fourteen different occasions.
The Parisian giants needed a stoppage-time leveler followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and secure a fourth straight French Super Cup victory.
The European champions appeared to be coasting towards a straightforward triumph in the showdown between the French league champions and the French Cup holders after Ousmane Dembele opened the net early on.
Yet, the southern French side struck two times late to take a surprise lead. Initially, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a vital leveler in the dying moments to force the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to seal a 4-1 shootout win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the past thirteen years.
