Power Tower also exists at Valleyfair! amusement park but in a slightly different form than the one at Cedar Point. The Minnesota version of this thrill ride has three legs and a triangular pyramidal crown and claims to be the tallest combination tower (has at least one of rapid drop and one of rapid ascent) ride in the nation. This record is controversial because the Cedar Point towers have a taller crown at 300 ft while the Valleyfair! tower crown is at 275 ft, but the actual ride at Cedar Point will only allow a 240 foot drop or ejection whereas the experience at Valleyfair! will reach 250 ft. Due to popularity and ride timing for the Turbo Drop towers, they outnumber the Space Shot Tower 2-to-1 in Minnesota. Both Power Towers were built by S&S Power of Logan, Utah.

The Valleyfair! tower is isolated on an island in the middle of the park and also gives a nice view of the corkscrew roller coaster below. And a suspension bridge entry/exit also provides theming to the ride.

While many people believe that the Valleyfair! executives simply stole the ride name from Cedar Point for convenience and marketing costs, there are some interesting points which may debunk this theory. In September 1999, Valleyfair! employees were offered a contest that would award a free t-shirt to the employee who could conjure the best name for the new unnamed ride (whose specifics had already been revealed to park employees at that point). Idiotically, an employee entered the ride name Power Tower after the similar ride that already existed at Cedar Point. This employee managed to win the contest, and a seasonal rides supervisor added the tagline "250 feet of extreme scream" which allowed a more edgy image for the ride. Furthermore, Valleyfair! improved the ride logo with a new fantastic font and moved the explosion lines to the perimeter of the logo.
