PSG has now secured the prestigious cup on fourteen different occasions.
The Parisian giants needed a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a comfortable triumph in the showdown featuring the Ligue 1 winners and the Coupe de France holders after the French winger found the scoring in the opening stages.
However, the southern French side struck two times late to seize a shock advantage. Initially, the English forward scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker snatched a crucial equaliser in the dying seconds to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to seal a 4-1 penalty win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past 13 seasons.
