That issue was for the first release drivers and for people who didn't pay attention to the power draw of the GPU in their system(plus the entire system's power draw) and/or for people with dodgy PSU's.
To be blunt, the GPU underneath is the same for all AIB partners. The only differences are their implementation of power delivery, higher quality components on VRM and different cooling assemblies. If the drivers are the issue, the issue would be for all AIB partners.
