PSG has now won the prestigious trophy on 14 separate occasions.
The Parisian giants required a stoppage-time leveler followed by a perfect spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match featuring the Ligue 1 winners and the Coupe de France winners after the French winger found the net 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 unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker grabbed a crucial leveler in the dying seconds to force the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a 4-1 shootout victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this competition for the twelfth time in the past thirteen years.
