The Parisian club has now claimed the prestigious cup on 14 different times.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be sailing towards a comfortable win in the showdown between the Ligue 1 winners and the French Cup holders after the French winger found the scoring in the opening stages.
Yet, Marseille fired two times late to take a shock lead. Initially, Mason Greenwood converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker snatched a crucial leveler in the dying seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for PSG to complete a 4-1 penalty win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the last 13 years.
