PSG has now secured the season-opening cup on 14 separate times.
The Parisian giants needed a stoppage-time equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward win in the match between the Ligue 1 champions and the French Cup holders after the French winger opened the net in the opening stages.
Yet, Marseille struck two times in the closing moments to seize a shock lead. First, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a crucial leveler in the dying moments to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, stopping decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for PSG to complete a 4-1 shootout win.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the past 13 years.
