The Parisian club has now secured the prestigious cup on 14 separate occasions.
The Parisian giants needed a dramatic equaliser followed by a successful spot-kick decider to get past Marseille in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The Champions League holders appeared to be coasting towards a comfortable triumph in the match between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele found the scoring early on.
Yet, the southern French side struck twice in the closing moments to take a surprise lead. First, the English forward converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a crucial leveler in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to seal a 4-1 penalty victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past thirteen seasons.
