1070's max power isn't 250W, not sure where you got that from. It's
150W. Thus 65% would make it run at 98W. Yours runs at 161. You'd never be able to run it at above 180W, let alone 250.
250W is 1080Ti's max power.
Like it says on the top of the specifications in your link, the 150 W power limit is for the
reference cards. The Zotac AMP! Extreme 1070 is a dual 8-pin card with a max power of 250 W.
https://www.zotac.com/us/product/graphics_card/zotac-geforce-gtx-1070-amp-extreme#spec Quite a few 1070 models have a default 180 watt TDP.
MSI makes at least 1 and I think 2 with a 240 watt TDP in their "Gaming" series.
This is WHY I keep trying to tell folks "specify watts, NOT PERCENT" on TDP numbers as % means NOTHING unless you specify the specific card model and even THEN it's confusing.
