The Parisian club has now claimed the prestigious trophy on fourteen separate times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward triumph in the match between the Ligue 1 winners and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
However, the southern French side fired twice in the closing moments to take a surprise lead. First, Mason Greenwood scored from the spot-kick, before the defender inadvertently 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 final seconds to force the match into a deciding 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 Desire Doue all scored with composure for PSG to complete a convincing shootout win.
Now 14-time winners Paris Saint-Germain, who faced 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 thirteen years.
