Normally the SF850L should have 300W and the 1000W unit 450W. The units I tested had 600W but I cannot know if Corsair will change that in the other production batches, to meet Intel's requirements. 

I have question about load regulation at 12V for SF1000L. You wrote that that it was more than 1% but in table it look good. You also mentioned on Youtube that Corsair would send you another sample. The problem still exist?

I checked cybernetics test for both and for load regulation (230V) SF1000L looks almost the same (or better) then SF850L.

thanks

I didn't find the time to retest it, unfortunately. 

thank you

I tested SF1000L and in HWiNFO the value for +12V for most time (without gaming) is 12.076V

Sometimes it goes up to 12.172V and goes down to 12.076V. 

Is it something similar that you mentioned? Should it be consider as an issue?

Any impact on system, stability?

Mainboard sensors are far from accurate, so don't pay much attention to what they report.
