PSG has now secured the season-opening trophy on 14 separate times.
Paris Saint-Germain needed a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in the Gulf and capture a fourth straight French Super Cup victory.
The European champions seemed to be sailing towards a straightforward win in the showdown between the French league champions and the French Cup winners after Ousmane Dembele found the scoring early on.
Yet, the southern French side fired twice late to take a shock advantage. Initially, the English forward scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a vital equaliser in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing shootout victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the last 13 seasons.
