PSG has now claimed the season-opening cup on 14 separate times.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown between the French league winners and the French Cup winners after Ousmane Dembele opened the net early on.
Yet, the southern French side fired two times in the closing moments to seize a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a crucial leveler in the dying moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a convincing shootout victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the last thirteen years.
