So those miner motherboards with the crap ton of PCIe x1 slots typically have a molex connector on the motherboard for each of those slots. Molex is famous for starting fires. I’m not sure I would ever go with a setup with molex connectors, but then I’m not sure you have another option. The issue is if they used PCIe power connectors instead, you often wouldn’t have enough of those left over for your GPU, so I get why they went with molex, it’s just a very old, and by modern standards crappy connector. Combined with the ~1800W per 15A circuit restriction (I wouldn’t load the circuit to 100%, so really ~1600W) I’m not sure you can achieve what you’re going for. If you’re really wanting to do this, consider adding a say 30A circuit near the circuit breaker of your home, usually the garage or basement and put the equipment there. I would get a dehumidifier in either location.
