I dunno, a standard residential US circuit is max 15A at 120V, or 1800W. A GTX980 is 165W and the highest powered Xeon I could find was 165W. A Xeon + 4 GPUs + power supply loss comes to around 1050W and between the motherboard, RAM, SSDs, HDDs, monitors, speakers, cooling and such I'm sure you can push it high enough that it causes issues but I really can't see that coming from a laptop, even with peripherals.
