Aces beat the PSL team by two goals to nil, with goals from former Kaizer Chiefs striker Kabamba Musasa and Essau Mtsweni.
The First Division side join Winners Park and Ikapa Sporting United as minnows who made it to the last 16.
Musasa was set up by Jacob Machaka's in the 36th minute. The midfielder beat three defenders before finding the striker unmarked in the box.
After prolonged pressure from Aces in the second half, Mtsweni made use of the muddy field to slide and knock the ball home six minutes from time.
The draw for the next round of the Cup will take place on Monday at 11.30am.
