The Parisian club has now claimed the prestigious trophy on fourteen different times.
The Parisian giants required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable win in the match between the Ligue 1 champions and the Coupe de France holders after the French winger found the net in the opening stages.
Yet, the southern French side struck two times late to seize a surprise lead. First, Mason Greenwood scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a vital leveler in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted successfully for Paris Saint-Germain to seal a 4-1 shootout win.
The record 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 past thirteen seasons.
