The Parisian club has now won the season-opening cup on fourteen different occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a fourth straight French Super Cup victory.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown featuring the French league winners and the Coupe de France winners after the French winger opened the net early on.
However, the southern French side fired two times in the closing moments to seize a shock lead. Initially, the English forward converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a crucial equaliser in the dying moments to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to complete a 4-1 shootout win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past 13 years.
