PSG has now secured the prestigious cup on 14 separate times.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable win in the showdown between the French league champions and the Coupe de France winners after the French winger opened the scoring early on.
However, Marseille struck twice late to seize a shock lead. First, the English forward converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker snatched a crucial leveler in the final moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial kicks from Matt 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 convincing penalty victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past 13 seasons.
