PSG has now secured the prestigious cup on fourteen separate occasions.
The Parisian giants needed a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable triumph in the match between the French league winners and the Coupe de France winners after the French winger opened the scoring early on.
However, the southern French side struck two times in the closing moments to seize a shock advantage. First, the English forward converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a vital leveler in the dying moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a convincing shootout win.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the past thirteen years.
