PSG has now secured the season-opening cup on 14 different occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward triumph in the showdown featuring the Ligue 1 winners and the French Cup holders after the French winger found the net early on.
However, Marseille fired twice late to seize a surprise lead. Initially, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos snatched a vital leveler in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for PSG to seal a convincing penalty victory.
The record champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this competition for the twelfth time in the last 13 seasons.
