PSG has now won the season-opening cup on fourteen separate times.
The Parisian giants required a stoppage-time equaliser followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be sailing towards a comfortable win in the match featuring the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele found the net early on.
Yet, the southern French side struck twice in the closing moments to take a shock lead. Initially, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a crucial leveler in the dying moments to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the hero, saving crucial attempts from O'Riley and Hamed 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 shootout victory.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the twelfth time in the last 13 years.
