PSG has now won the prestigious trophy on fourteen different occasions.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable win in the match between the Ligue 1 champions and the French Cup holders after the French winger opened the net early on.
However, Marseille fired twice late to take a surprise advantage. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a vital leveler in the dying moments to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a convincing penalty victory.
Now 14-time champions 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 last thirteen years.
