PSG has now secured the prestigious cup on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable triumph in the showdown featuring the French league champions and the French Cup holders after the French winger opened the net early on.
However, Marseille struck two times in the closing moments to seize a shock advantage. First, the English forward scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital equaliser in the dying seconds to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a 4-1 penalty win.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this competition for the twelfth time in the last thirteen seasons.
