T15/s15 do not have much support or no modded firmware support if I were you instead buy a used s9 because it's more flexible you can use other firmware like Braiins OS and then use auto-tune to set it mine at that power.
no not if you have 220-240 volt power.
the s15 set to low on stock bitmain firmware.
destroys the s9
20th at 900 watts low s15
9 th at 720 watts low s9 with special firmware.
one is under 50 watts a th the s15
other is 80 watts a th the s9
Now you must have 220-240 volt power to do this.
Edit an old s17 set to low will do 1300 watts and 40th
see below 39.76th and 1330 watts braiins+ BTW you could drop lower like 1200 or 1100 or even 1000
The psu fans are a bit loud on this unit but it would likely work for you.
