Roderick Mangubat and Rayjund Trespicio sparked People Support's blazing run as they fired 28 and 20 points, respectively.
The impressive performance of Mangubat, who hauled 19 markers in the opening period, rolled off People Support to a 38-34 lead at halftime.
Convergy's Mark Lerio tried to catch up with People Support's run and gun game by taking matters into his own hands but efforts proved futile as Trespecio's two triples in the final quarter helped stir the win.
People Support now sports a 1-2 win-loss card in the ongoing second round, jumping from a poor 0-4 finish in the first round.
