The Parisian club has now won the season-opening trophy on fourteen separate occasions.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be sailing towards a comfortable triumph in the match between the French league champions and the French Cup winners after the French winger opened the scoring in the opening stages.
However, Marseille fired two times late to seize a surprise advantage. First, the English forward converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a vital leveler in the final moments to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, saving crucial attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 penalty victory.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the past thirteen seasons.
