The Parisian club has now claimed the prestigious cup on 14 different times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable win in the match featuring the French league champions and the French Cup winners after the French winger found the net early on.
Yet, the southern French side fired two times late to seize a surprise advantage. First, Mason Greenwood converted 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, the Portuguese striker snatched a vital leveler in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving decisive kicks from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the last 13 seasons.
