PSG has now won the season-opening trophy on fourteen separate times.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be coasting towards a comfortable win in the match featuring the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele opened the net early on.
However, Marseille fired twice in the closing moments to take a shock lead. First, the English forward converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker snatched a crucial leveler in the final moments to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for PSG to seal a 4-1 penalty win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past 13 years.
