The feature is that non-reference, especially factory-overclocked GPUs tend to have, quite often, increased power limits by default, from manufacturer. The default for reference AMD 6900XT is 255W, which results in 293W when +15% limit is applied, hence the advertized 300W max TDP. You can study the most basic settings of all 6900XT BIOSes HERE.
Yours in turn has default 281W TDP, which gives a result of roughly 315W (it's actually 314.72), so sli-i-ightly higher than reference.
If you want precise manual configuration, I would recommend getting an MPT (MorePowerTool) from HERE (official developer source, don't get it from other websites; Windows will warn you that it's malicious, but that is as expected since it is used to manually tweak the depths of your system), getting a snapshot of your VBIOS via GPU-Z, uploading it into MPT and setting your preferred limits in the "Power" section.
