The Parisian club has now claimed the prestigious cup on fourteen separate times.
Paris Saint-Germain required a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in Kuwait and capture a fourth straight French Super Cup victory.
The European champions appeared to be sailing towards a straightforward triumph in the match between the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the scoring early on.
Yet, the southern French side fired twice late to take a shock advantage. Initially, the English forward scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a vital leveler in the final seconds to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a 4-1 shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the last thirteen seasons.
