Olympics will be tough for Blitzboks
South Africa, who are seeded second at the event, were drawn alongside Australia, France as well as Spain and Powell believes that all the pools will be tough.
"I am pleased with our pool, but the reality is that you will have to respect every opponent, play every game at your best and use your opportunities. There will be no easy games and there are no easy pools.
"Even Brazil, who are seeded 12th, will be a very tough nut to crack as they will be playing in front of their home crowd. We need to prepare well because the other pools are also very competitive. As a team, we don't look too far ahead.
"We will focus on our first match on Day One, hoping to do well and to build from there," Powell said.
In the men's competition to be played from August 9-11, World Series champions Fiji are the top seeds in Pool A and are drawn with defending Olympic champions USA, as well as South American rivals Argentina and Brazil. Pool C will also be very competitive as New Zealand will play Great Britain, Kenya and Japan.
The top two teams from each pool plus the two best third-placed sides will advance to the quarter-finals.
