PSG has now claimed the season-opening trophy on 14 separate occasions.
Paris Saint-Germain required a dramatic equaliser followed by a successful spot-kick decider to get past Marseille in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward win in the match featuring the French league champions and the French Cup winners after the French winger found the scoring early on.
However, the southern French side fired two times late to take a surprise lead. First, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a crucial leveler in the dying moments to force the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 penalty win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the last 13 years.
