So a rated 3500 watt unit will sometimes do 3650 watts.
you are 100% correct! I ordered several S21's but only 1 from the jan batch. I can say, with the utmost certainty, it pulls on average 3.621 kW @ the wall. Your prediction is extremely accurate lol.
All the same - the miner averages about 204 TH/S which is solid. Hoping to be able to undervolt/underclock it for even greater efficiency (wouldn't sacrifice more than 10% HR - but if I can drop it .5-1.5 J/TH like I was able with my 19K Pros - i'll be happy.
You are very lucky newer got under 3900w
https://www.youtube.com/watch?v=NWVqNSx4YUI. 300 x 24 = 7200 watts a day.
35 cents a day at five cent power.
70 cents a day at 10 cent power.
A small commercial mine like mine has 70 pieces
we are near 5 cents.
so we lose 25 usd a day in power. or 9125 dollars a year.
It is a lot for us.
Totally get that, Phil. I am also a very small farm owner (smaller than you!) I have about 30 Machines running full time at 1 location, and about 8 at another. It, undoubtedly, hurts... I just had to pay a $5,961 power bill this afternoon. But - Even tuning my 19K Pro's down to about 98 TH/S utilizing the ePIC UMC's Voltage Optimizer, the S21 in LPM is still more efficient.
Is it like - absolutely revolutionary? No. Is it an improvement from what I was using prior? Absolutely. Also - comparing it to the MicroBT or Canaan offerings, it still seems to be the clear go-to choise from my perspective.
I actually just received a 188T S21 from Altair yesterday that I got up and hashing today - am VERY pleased to announce that thus far, it is pulling 3.38 kW @ 192 TH/S (average). I only have 2 S21's - will be taking delivery of several more in the next month or so. Will certainly update this thread with some power figures next time I drive up to my farm.
