The Parisian club has now won the prestigious trophy on fourteen different times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight French Super Cup victory.
The European champions appeared to be sailing towards a straightforward win in the match featuring the French league winners and the Coupe de France holders after the French winger found the net early on.
Yet, the southern French side fired twice in the closing moments to seize a shock lead. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos snatched a vital leveler 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.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 penalty win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this trophy for the 12th time in the past 13 years.
