PSG has now claimed the prestigious trophy on 14 separate times.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable triumph in the showdown featuring the French league winners and the French Cup winners after the French winger opened the scoring in the opening stages.
However, the southern French side struck twice in the closing moments to seize a shock lead. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker grabbed a crucial equaliser in the final moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving crucial kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to complete a convincing shootout victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the past 13 years.
