PSG has now won the season-opening trophy on 14 separate 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 record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be coasting towards a comfortable win in the showdown featuring the Ligue 1 winners and the French Cup winners after the French winger found the scoring early on.
Yet, the southern French side struck twice in the closing moments to take a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos snatched a vital leveler in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to seal a convincing penalty win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the last 13 years.
