The Parisian club has now won the season-opening trophy on 14 different times.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful penalty shootout to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward win in the match between the Ligue 1 champions and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
Yet, Marseille fired twice late to take 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 remarkable turn of fortune, the Portuguese striker snatched a vital leveler in the final seconds to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to complete a convincing shootout victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past 13 years.
