The Parisian club has now claimed the prestigious trophy on 14 different times.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward triumph in the showdown between the Ligue 1 winners and the French Cup winners after the French winger opened the scoring in the opening stages.
However, the southern French side fired two times in the closing moments to seize a shock lead. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos snatched a crucial equaliser in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this trophy for the twelfth time in the last thirteen years.
