PSG has now claimed the season-opening trophy on 14 different times.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable triumph in the match featuring the French league champions and the French Cup winners after the French winger found the scoring early on.
Yet, the southern French side fired twice in the closing moments to seize a surprise lead. 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 breathtaking turn of fortune, the Portuguese striker snatched a crucial leveler in the dying seconds to force the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, 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 successfully for PSG to complete a convincing shootout win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the last 13 years.
