PSG has now won the prestigious cup on fourteen separate times.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward triumph in the showdown between the Ligue 1 champions and the Coupe de France winners after the French winger found the scoring early on.
However, Marseille fired twice late to seize a surprise lead. First, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately 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 final seconds to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored with composure for Paris Saint-Germain to seal a 4-1 shootout win.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this competition for the 12th time in the past thirteen years.
