The Parisian club has now claimed the prestigious trophy on 14 different occasions.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be sailing towards a comfortable win in the match featuring the French league champions and the Coupe de France holders after Ousmane Dembele found the scoring in the opening stages.
However, the southern French side struck two times in the closing moments to take a shock advantage. 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 remarkable turn of fortune, Goncalo Ramos grabbed a vital leveler in the dying seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, stopping decisive kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to complete a 4-1 shootout win.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the last 13 years.
