But by default, 70 or 80% power limits is impossible to set. You can only set offset from 100% you are ABLE to set.

-2% means power limit will be 98%. To get to 70 or 80 you need to set -30% or -20% offset respectively. But for most consumer GPUs negative offset hardly goes below -6% or -10%

Resulting power limits in watts will be X (nominal power limit = 100%) * (100+X)% where X is what you set in driver settings. For example nominal power limit is 100W. You set offset to -7%. meaning resulting power limit in watts will be 100*(100+(-7))%=93W
