Hey guys, quick question. What's the power draw like if I run an S19 at 90TH but only connect one or two hashboards? I think with just one board it should hit around 30TH and need about 1100w, right? What do you think about the power save mode? Any ideas on how it performs?
Power Usage of S19 with Limited Hashboards

For low power mode, I’d say the hashrate drops to about 10% efficiency. So with just one hashboard working, you're looking at something like 24-27TH/s and around 800-990w in terms of power. If you're trying to optimize power usage, check out Braiins OS. I heard people managed to squeeze better performance by adjusting the power target. Setting it to 800w might bring you around 26-28TH/s, but that's just my guess.
Just to add, your power consumption will depend on the model you have. Typically, each hashboard pulls about a third of the total power. So if your miner's target is set at, say, 1677W, cutting off two hashboards would drop the draw to around 559W. But keep in mind, your power target stays at 1677, not 559. To maximize efficiency, aim to keep the chip temp at 60°C, but some say 55°C is ideal. Always good to do a bit of testing!
