The Parisian club has now claimed the prestigious cup on 14 different times.
The Parisian giants needed a dramatic equaliser followed by a successful spot-kick decider to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward win in the match featuring the French league champions and the French Cup winners after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side fired two times in the closing moments to seize a shock advantage. First, the English forward converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos snatched a crucial leveler in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to complete a convincing penalty win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past 13 seasons.
