PSG has now claimed the season-opening trophy on fourteen different times.
Paris Saint-Germain needed a dramatic equaliser followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and capture a record-extending fourth consecutive French Super Cup title.
The European champions appeared to be sailing towards a straightforward triumph in the match featuring the French league winners and the French Cup winners after Ousmane Dembele opened the net early on.
However, Marseille struck two times in the closing moments to seize a shock lead. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a vital leveler in the final moments to send the contest into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for PSG to seal a 4-1 shootout victory.
The record 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 past thirteen years.
