Power fluctuations on RTX 3080 Ti

I just added an RTX 3080 Ti to my rig and am getting around ~72-77 MH/s with the OC settings here.

Mining ETH with Nbminer

The issue is that the power draw on this card has been hopping in between ~115 - 280W quite often (see first vs. second pic). The hashrate stays around the same, but the power draw fluctuations have me concerned. Is there something specifically I should look into for this card? Any advice appreciated.
