Seems like 800-900 W might be the threshold and most optimal in terms of temperature and efficiency. I tried 1200, it overheated and restarted -- same result even at 1000.

Totally agree…and from everything I’ve seen in forums and Reddit seems like that’s the sweet spot. Lower (eg 650 W which I’ve tried) really chops the hashrate down, and you have diminishing returns at higher wattage. Getting 10 TH/sec at 800-900 seems the best, especially keeping it running happy for longer!
