It is unknown if the armor was destroyed or not.
The armor ran on a power source that Doctor Octopus created by copying the Arc Reactor specifications stolen from Stark Industries. But, because Iron Man didn't put 'the good stuff' in the specifications, the power source could not self-sustain itself.
