The Parisian club has now claimed the prestigious cup on fourteen different occasions.
Paris Saint-Germain required a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a straightforward win in the match featuring the Ligue 1 winners and the Coupe de France holders after the French winger found the net early on.
However, the southern French side struck two times late to seize a shock advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a crucial leveler in the dying seconds to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving decisive kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a convincing penalty win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the last 13 years.
