The Parisian club has now claimed the prestigious cup on 14 separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a straightforward win in the showdown featuring the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele opened the net early on.
However, Marseille struck twice late to take a surprise lead. First, the English forward converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker grabbed a crucial equaliser in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, stopping crucial attempts from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to seal a 4-1 shootout victory.
The record champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the past 13 seasons.
