I am running my Ryzen 5 7600 and RTX 3080 off a Superflower Leadex III 550W. So when my GPU is under full load and drawing 360, 370W it gets pretty scary considering that's 2/3 of my PSU capacity.
But when I try the undervolt curve in the picture (850mV/1852MHz) and run 3DMark TimeSpy Demo and use MSI Afterburner to monitor the GPU core clock, voltage and power, the power draw remains the same at 360, 370W at 100% utilisation. I thought by reducing the clock speed and voltage below stock I can severely reduce the power draw. Am I doing something wrong?
I read that setting power limits is not advised as it can cause stutters at full load, so I'm not sure what else I can do.
These 2 videos from Optimum and Cynikaly show 100W lower power draw, why can't I achieve the same thing? Any advice is appreciated, thanks 🙏

Looks about right in MSI AB…check out this LTT video for UV on a 4090 to see if you’ve applied something incorrectly: [https://youtu.be/yU4CFhtS95Q?t=827](https://youtu.be/yU4CFhtS95Q?t=827)
I don’t know if lowering the power limit will immediately cause stutters…theoretically it should just reduce the overall performance.
In the end you may want to consider simply grabbing a larger PSU. [HWBusters.net](http://HWBusters.net) is a good place to find excellent PSU reviews.
You likely forgot to hit apply.
