The Jackets (7-3) broke the game open midway through the second half, building a 45-32 lead at 16:32 into a 71-36 lead at 8:47 with a 26-4 run as they held GSU to two lay-ups in that eight minutes.
Four Yellow Jackets scored in double figures, topped by 6-foot-5 center Sasha Goodlett with 16 points on 7-of-11 shooting. Guard Tyaunna Marshall added 15 points.
Georgia State got 12 points from point guard Jerlisa Taylor, along with 11 points from guard Kendra Long, to go with 10 rebounds and nine points from forward Chan Harris.
Georgia State struggled with a 19.2% percent first half, making just five of 26 shots as visiting Tech took a 36-19 advantage into halftime.
"Obviously, the first half was flat-out horrible and you can't win shooting like that," said head coach Sharon Baldwin-Tener. "We couldn't even make free throws standing still (17-of-35, 48.6%) so we will continue to focus on shot selection and techniques."
"We played with some energy, forced some turnovers (18), blocked some shots (7) and got ourselves to the free throw line by being aggressive (35 free throws)," Baldwin-Tener added. "But, you have to make shots and score points to win, so that is our priority to get better at that right now."
Georgia State will leave Saturday for the Bahamas for the SunSplash Shootout with games on Monday and Tuesday nights in Nassau.
