The Parisian club has now secured the prestigious cup on 14 separate occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a comfortable win in the showdown featuring the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side fired two times in the closing moments to seize a surprise lead. First, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a vital equaliser in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a 4-1 shootout win.
The record winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the last thirteen years.
