PSG has now secured the season-opening trophy on fourteen different times.
Paris Saint-Germain required a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be sailing towards a straightforward win in the showdown between the French league champions and the French Cup holders after Ousmane Dembele opened the net early on.
However, the southern French side struck two times in the closing moments to take a surprise advantage. First, Mason Greenwood converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a vital leveler in the final moments to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for PSG to seal a convincing shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last thirteen years.
