The Parisian club has now claimed the prestigious cup on 14 separate times.
The Parisian giants needed a stoppage-time leveler followed by a successful spot-kick decider to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable triumph in the match between the French league winners and the Coupe de France winners after the French winger found the net early on.
Yet, the southern French side fired twice late to seize a surprise advantage. Initially, the English forward scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos snatched a vital equaliser in the dying seconds to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, saving crucial kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted successfully for Paris Saint-Germain to seal a convincing penalty victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this trophy for the 12th time in the past thirteen seasons.
