I found the following rigs from ASIC Miner Value. They all have a power consumption of less than 1920 W. (120v x 20 amp = 2400 W, with 80% rule = 1920 W)

Innosilicon A10 Pro+ ETH (750Mh) 1350W

Innosilicon A10 Pro ETH (500Mh) 960W

Bitmain Antminer DR5 (34Th) 1800W

Does it mean that these rigs can run on 120v 120 amp circuits? It seems too good to be true seeing that the profit for these rigs are so high. Am I missing something?

My apartment only has 120v 20 amps circuits. Is it possible to convert them to 220v? It is an unit within a 20 story building.
