The Parisian club has now claimed the prestigious trophy on fourteen different times.
The Parisian giants required a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward win in the match between the French league winners and the Coupe de France winners after the French winger found the scoring in the opening stages.
Yet, the southern French side struck two times in the closing moments to take a shock advantage. Initially, the English forward scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a vital leveler in the dying moments to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving decisive attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 shootout win.
Now 14-time winners 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 competition for the 12th time in the past 13 seasons.
