PSG has now claimed the prestigious cup on 14 different times.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward triumph in the match featuring the Ligue 1 champions and the Coupe de France holders after the French winger found the net in the opening stages.
Yet, Marseille struck two times late to take a surprise advantage. First, the English forward converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a crucial leveler in the dying seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping crucial attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this competition for the 12th time in the past thirteen seasons.
