GTX 1660 Ti and GTX 1660 min power levels?

What are the minimum power levels the cards will accept in Linux?

using command:

nvidia-smi -i 0 -pl ???

Where the ‘???’ are being replaced with the minimum values the card will accept?
I can’t find any data on this online!

It used to be 50%.

It actually takes less than a minute to find out the answer - try different values - there aren’t that many of them.

I don’t own the cards, and I don’t want to buy them to figure it out.
The 1030 is 25.5W, the 1050 is 65W, any RTX card is 125W, except for the 2080Ti (which is 110W).
