The Parisian club has now won the prestigious trophy on fourteen different times.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable win in the match featuring the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele opened the net early on.
Yet, the southern French side struck two times late to seize a shock lead. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial leveler in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to complete a 4-1 shootout victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the last thirteen seasons.
