PSG has now secured the season-opening trophy on 14 separate times.
Paris Saint-Germain required a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward win in the match between the French league champions and the Coupe de France winners after Ousmane Dembele opened the scoring early on.
Yet, the southern French side struck two times late to take a shock lead. Initially, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial leveler in the dying seconds to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to seal a 4-1 penalty victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this trophy for the 12th time in the last thirteen years.
