The Parisian club has now won the prestigious cup on 14 different occasions.
Paris Saint-Germain required a dramatic equaliser followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable triumph in the match featuring the French league winners and the Coupe de France winners after the French winger found the net in the opening stages.
Yet, the southern French side fired two times in the closing moments to seize a surprise advantage. First, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital leveler in the dying seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to complete a 4-1 shootout win.
The record champions PSG, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this competition for the 12th time in the last thirteen years.
