Woo! 2400 watts. That's a big one. I'm definitely not gonna push the PSU to that limit. Maybe a few hundred watts at most, at first.
But yes, I installed a 100 amp subpanel just for mining with one 15 amp 240v circuit and one 15 amp 120v circuit. It's only 15 amps cause I only planned on using a small ASIC. And then only using a couple GPUs doesn't pull that much either.
