PSG has now claimed the season-opening cup on 14 different times.
Paris Saint-Germain required a dramatic equaliser followed by a successful spot-kick decider to get past Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a straightforward triumph in the match between the Ligue 1 champions and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side fired two times in the closing moments to take a surprise advantage. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial leveler in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for Paris Saint-Germain to seal a 4-1 penalty win.
Now 14-time winners Paris Saint-Germain, 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.
