PSG has now won the prestigious cup on fourteen separate times.
Paris Saint-Germain required a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown featuring the Ligue 1 winners and the French Cup holders after Ousmane Dembele found the net in the opening stages.
Yet, Marseille fired twice late to seize a shock lead. First, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos snatched a vital leveler in the dying moments to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping decisive attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a convincing shootout win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this competition for the twelfth time in the past thirteen seasons.
