That is true. Though, if memory serves me well, I think I was using one decent power supply and one cheap in the lab, and both Pandas were failing randomly.

Matt, if you could have a look at my rack shelf (it's the top one with the chromebook in it), there should be a power supply with a velcro on it. I only used the cheap one on my second Panda, because that was the one I was using to set it up on my desk.

Furthermore, mine were not the only Pandas failing when running toolchain testing and benchmarking...

There are plenty of other
components on the board, any of which could be causing the problem,
including the peripherals that you plugged in.

Just network and a USB thumb drive. Shouldn't be problematic.

I don't have a PSU at home nor a decent power supply here, so I can't perform this test, but I'm not really sure it will make a difference based on what happened in the lab rack.
