PSG has now claimed the prestigious trophy on fourteen different occasions.
The Parisian giants required a stoppage-time equaliser followed by a successful spot-kick decider to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward win in the showdown between the French league champions and the French Cup winners after Ousmane Dembele found the net in the opening stages.
However, the southern French side struck twice late to take a surprise lead. Initially, the English forward converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a vital equaliser in the final seconds to force the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for PSG to seal a 4-1 shootout win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now won this competition for the 12th time in the last thirteen years.
