The Parisian club has now claimed the prestigious cup on 14 separate times.
Paris Saint-Germain required a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable triumph in the match featuring the French league winners and the French Cup holders after Ousmane Dembele found the net early on.
Yet, the southern French side struck two times late to seize a surprise advantage. Initially, the English forward scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker snatched a vital leveler in the final seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for PSG to complete a 4-1 penalty win.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the last thirteen seasons.
