PSG has now won the season-opening cup on 14 separate times.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable triumph in the showdown featuring the French league winners and the French Cup winners after Ousmane Dembele found the net in the opening stages.
However, Marseille fired twice late to seize a surprise advantage. Initially, the English forward converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial leveler in the dying moments to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to seal a convincing penalty win.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the past 13 years.
