PSG has now claimed the prestigious trophy on fourteen separate times.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a straightforward win in the match featuring the Ligue 1 winners and the French Cup holders after the French winger found the net in the opening stages.
Yet, Marseille struck two times late to take a surprise lead. First, the English forward converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a crucial leveler in the final moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to seal a 4-1 penalty victory.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this trophy for the 12th time in the last thirteen seasons.
