I also have a corsair PSU with Corsair Link enabled, and it reports about 70W more consumption than my wattmeter. So, Corsair link ~ 900, wattmeter 820.
Which one should i trust?
What input voltage your wattmeter and your Corsair Link is reading?
I have the same question. Does the Corsair link give similar reading to the one from the wattmeter?
