Here's a video I made today showing comparison of T-9 11.5 vs. S-9 12.0 variable frequency power draw at the wall. Uses more power, but runs cooler.

At 210 VAC
T-9 uses 1352 W, hashes at 11.5, highest chip temp 80C

S-9 uses 1329 W, hashes at 12.0, highest chip temp 94C

Thanks for the video Jack. How strange the S9 is using so much more power than the stated specs on the web site. I think they quoted something like 1079w for the 12th S9 so that is significantly above the spec.

Really looks like the T9 may be a winner then just based on the cooler temps and the power use looks like it isn't as bad as was stated in the spec for that unit. Good to know! The T9 may turn out to be a good unit! Please keep us posted.

Well, in the first video I made I compared it to a 550 fixed frequency S-9 at 11.85 TH. The older 550 speed S-9 used only 1178 watts. I think when Bitmain changed to variable frequency they didn't update the specs on the S-9
