The Parisian club has now claimed the prestigious cup on 14 different times.
The Parisian giants required a stoppage-time leveler followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward win in the match between the Ligue 1 champions and the Coupe de France holders after the French winger found the net early on.
Yet, the southern French side struck two times in the closing moments to take a surprise lead. Initially, the English forward converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial equaliser in the final seconds to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing penalty win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this competition for the twelfth time in the last 13 seasons.
