The Parisian club has now won the season-opening cup on fourteen separate occasions.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable triumph in the showdown between the Ligue 1 champions and the French Cup holders after the French winger found the scoring early on.
However, Marseille struck two times in the closing moments to take a shock advantage. Initially, the English forward 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 fortune, Goncalo Ramos grabbed a crucial leveler in the dying moments to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving decisive attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to seal a 4-1 penalty win.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the past thirteen seasons.
