Finally got around to setting up Printrbot. Got a good deal for Thansgiving.
Since it was a preassembled printer, expected to start up right away. The heated bed option comes with an ATX power supply instead of laptop power supply. Mine came with a 6-pin Molex connecter for the power supply. Note that the ATX power supply should have matching 6-pin. This caused a little bit of confusion since Printrbot docs so not explicitly say that.
Printrbot support came through and confirmed it. Happy with the response time it being Sunday and all.
