PSG has now claimed the season-opening cup on fourteen different occasions.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout to get past 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 triumph in the match between the Ligue 1 champions and the French Cup holders after Ousmane Dembele opened the net early on.
Yet, the southern French side struck two times late to take a surprise lead. First, the English forward converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a vital equaliser in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to seal a convincing penalty win.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the last 13 years.
