PSG has now claimed the season-opening cup on fourteen separate times.
The Parisian giants required a stoppage-time leveler followed by a perfect spot-kick decider to overcome Marseille in the Gulf and capture a fourth straight French Super Cup victory.
The European champions appeared to be coasting towards a straightforward triumph in the match featuring the Ligue 1 winners and the Coupe de France holders after the French winger opened the scoring early on.
Yet, Marseille fired two times late to seize a surprise lead. First, Mason Greenwood 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 grabbed a vital leveler in the dying seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping decisive kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a convincing shootout victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the past thirteen years.
