PSG has now won the season-opening cup on fourteen separate occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a fourth straight French Super Cup victory.
The Champions League holders seemed to be sailing towards a comfortable triumph in the match featuring the Ligue 1 champions and the French Cup holders after the French winger opened the scoring in the opening stages.
However, Marseille struck twice in the closing moments to take a surprise advantage. First, 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 grabbed a vital leveler in the final seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 penalty win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
