The Parisian club has now secured the prestigious trophy on 14 different times.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable triumph in the showdown featuring the French league winners and the French Cup winners after the French winger found the net in the opening stages.
However, the southern French side fired two times late to seize a shock lead. First, the English forward converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital leveler in the final moments to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for PSG to seal a 4-1 penalty win.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past thirteen seasons.
