South Africa lost in the semifinal of the Singapore tournament on the weekend to Fiji, before claiming bronze when they beat Argentina 28-0 in the third-place playoff.
Finishing third saw them overtake New Zealand in second place on the series standings.
But that is not disheartening the coach, who says: “The margins in Sevens are so small and when we play Fiji or New Zealand, it is always just one try that proves the difference.
“So that Fiji tackle on the corner flag on Stephen Dippenaar preventing him from scoring what probably would have been the match-winner shows how tight the margins are. I cannot blame the players for lack of effort.
“Whenever they take the field, they really play for that jersey and each other. They left nothing out there.
“I believe firmly we are on the right track to be a very successful team.”
Of their win over Argentina, Powell says: “They [Argentina] really came for us in that first half and we managed to keep them out.
“I wanted to give the guys mostly playing off the bench some proper game time and they responded well to that challenge. The extra two points we collected by winning that final is also very important and helped us back into second overall.”
