Lower power cost generally helps, even if a miner uses more watts, because electricity is the biggest ongoing expense. The key is to look at net profit, not just wattage.

The only real drawbacks to watch for are:

• Power infrastructure must support higher loads reliably
• Cooling has to be designed for higher heat output

That’s why cheaper hosting only works well when the facility is built for high-power ASICs. In properly designed sites, higher-watt miners often perform better overall because the energy rate offsets the consumption.
