PSG has now secured the prestigious trophy on fourteen different occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable triumph in the showdown between the Ligue 1 winners and the Coupe de France holders after the French winger opened the net in the opening stages.
Yet, the southern French side fired twice late to take a shock lead. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos grabbed a crucial leveler in the final moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a 4-1 shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the past 13 seasons.
