PSG has now won the season-opening trophy on fourteen separate times.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to get past Marseille in Kuwait and capture a fourth straight French Super Cup victory.
The Champions League holders appeared to be coasting towards a straightforward win in the showdown between the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the scoring early on.
However, Marseille struck two times late to take a surprise lead. First, the English forward converted from the spot-kick, before the defender inadvertently directed 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 penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping crucial attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a convincing shootout win.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past thirteen seasons.
