Powerlines FC (0) 0 - Mamelodi Sundowns (10) 24
Sundowns showed professionalism throughout the match, with no showboating even though they led 10-0 at half time.
The Pretoria side had six different scorers on the day as they compiled a total more in harmony with the rugby matches usually played at the GWK stadium.
Nyasha Mushekwi scored six goals before being substituted by Lebohang Mokoena late in the second half.
Hlompho Kekana, who had opened the scoring for Sundowns as early as the eighth minute, passed his career goal tally for Sundowns in one match - clinically netting seven goals.
Kimberley home boy Richard Henyekane also put five goals past Powerlines goalkeeper Thabang Louw, who, to his credit, did make a few saves to prevent the scoreline from reaching half a century, though he was let down by his defence.
Samuel Julies came off the bench for Sundowns to get in on the act, scoring two goals and spending the better part of the second half trying to get a hat-trick.
Elias Pelembe was more of a provider in the first half of the cup encounter, but got on the score sheet twice. Mokoena himself scored two goals minutes after replacing Mushekwi.
This was a record scoreline in a cup competition of this format. In 1976, Amazulu thumped Bizana All Stars 16-0, but Sundowns were determined to smash all records.
They also surpassed their own milestone as a club, having had 7-1 victories against QwaQwa Stars (1988), Santos (1998) and Vaal Professionals (1999) as their biggest wins in the team's history.
Downs coach Johan Neeskens said the visitors had opted not to sit back in the latter stages, out of respect for their hosts, the spectators and the competition.
"We must respect all teams in the Nedbank Cup," Neeskens said. "We must always play the best we can and score as many goals as possible. We also need to entertain the fans."
Powerlines coach Cornelius Brandt said his side would hold their heads high despite their thumping defeat.
"Our heart and our spirit are not broken," Brandt said. "This is Mamelodi Sundowns and they're a good team. The clubs in our league will suffer after the experience we got from this game."
Brandt said he had tried to motivate his players during the break but they were up against a wall.
"I asked them to calm down and to relax," he said. "It seems the stage was too big for them and they fell away."
In the only other cup game yesterday, Supersport United beat Batau FC 4-2 on penalties after the scores were locked at 1-1 after extra time.
The draw for the round of 16 will take place next Monday. - Additional reporting by Sapa
