I think that all the PSUs come from China, even the good ones like seasonic.

I get 330-345 on a 6g oced (2088mhz core clock, 4498 memory clock)
And around 300 on the same card at stock speeds (its a msi gaming x, so it has some factory oc)

Hey I just created this account to say thanks, started mining 2 weeks ago because why not. I got a little boost from this version with a 1060 6gb, I never say anything higher than 345 sol/s previously, and in couple minutes already say a 349 sol/s. If I see a 350 i'll flip out.
