ISS program manager Mike Suffredini said a meeting had concluded "with a go for SpaceX-3."
"We had already determined that we were ready for the launch early last week, however, Friday afternoon one of our external MDMs failed," he said, referring to a backup command computer relay box.
There are around 10 MDMs on the space station, controlling automated systems on the base. A spacewalk will be required to repair the computer.
NASA was keen for the SpaceX rocket to fire its cargo to the base as quickly as possible.
"SpaceX is carrying on board a number of critical systems, including a new spacesuit, components to fix the existing spacesuits, a couple of very critical research experiments in the trunk and quite a bit of logistics for our crew members on board," Suffredini said.
"So we need to get it onboard as soon as we practically can," Suffredini said.
Owned by Internet entrepreneur Elon Musk, SpaceX became the first commercial entity to reach the space station with its Dragon cargo ship in 2012.
The company has a $1.6 billion contract with NASA for a series of future supply missions.
The Dragon, a reusable, gumdrop-shaped capsule, became the first commercial spacecraft to reach the ISS in 2012.
