The 2060 uses anywhere between 170 and 190 Watts, depending on manufacturer and card type.
Most of my card's configuration caps off at 225Watts, but even under 100% load and stock speeds, they're not using more than 190Watts (some don't use more than 175Watt).
It depends from card to card.
Also, most of my 2060s cap off on the bottom at 125Watts, which seems universal for most 2060, 2070 and 2080 cards. I could be wrong here, but it's my experience.
There may be an exception in that the 2070 has been given the same power control as the 2080, but due to lower transistor count, can do the same with lower power (as the 2080 caps off at 125Watts as well).
I will know soon enough, as my first 2070 will arrive in 2 days.
The 2060 has less control over its power modules. It's working range is much smaller.
Go to the GTX series, and you have even less control.
Eg: the 1050 only goes from 60-65W, to 75W stock, to 120W max, but generally never uses more than 75 watts under full load and overclock.
So basically, on the 1050, you can only control the lower 10-15 watts with nvidia-smi, since it won't ever hit anywhere near 120Watts under serious (air or watercooled) overclocking (unless we're talking about liquid cooled nitrogen perhaps; but even then...). I've never seen my GTX 1050 use over 73Watts.
It is my experience with cards, that increasing them about 5Watts from the lowest setting (125Watts to 130Watts), increases overall system power consumption by an actual 9 Watts, which accounts for an increase of 8%, yet the speed increase is over 10%.
So my suggestion to you, is to keep it running at 5-10W above the minimum settings. At 125Watts the cards throttle too much.
