Been using AMD GPUs and hence AMD Adrenalin for a while and so far I can just drag a voltage slider in the app to undervolt my GPU but I recently upgraded to a used RTX 3080. Pretty scary to see it suck 300W alone when my Superflower Leadex III only has 550W to spread across the entire PC. When I downloaded MSI Afterburner I'm confused on what to do with this graph concerning voltage and frequency, and what points to shift.

So how would I go about reducing the power draw of my RTX 3080, without just setting a hard power limit? I would like to try and retain it's stock performance while reducing the power draw/thermals/fan speed etc.

Any advice?
