I've got a 9070XT Steel Legend graphics card, and during stress tests, I noticed something odd. On Windows, the power draw caps at 304 watts with all stock settings and no tuning. However, when I run the same test on Fedora Kinoite, it jumps to 396 watts, which really surprised me. I understand that you can use LACT to limit power consumption. But I'm wondering why there's such a big difference in reported power usage between the two operating systems. Is it because OCCT measures power consumption differently on Linux? Or is the stock power draw on Linux just that much higher?

💡 Smokey Tip: When posting about technical issues, always mention your distro, hardware details, and any error messages you encounter. It helps in getting better assistance! 🙂
Have you checked the power profile in both operating systems? Windows tends to default to a 'balanced' profile, while Linux might also be set to 'balanced' by default. Changing the power profile could impact your power draw significantly. Just a thought!
Could it be that Linux is showing Total Board Power instead? I've seen that jump over 500W on Windows, so maybe that's the discrepancy? It might be worth investigating.
You might want to report this on the FreeDesktop GitLab issues page. It could be a bug, or they might clarify why the power usage is so different between the two systems. Sharing your experience could help others too!
I haven't manually checked Kinoite's setting, but I found online that it also defaults to 'balanced'. It makes me wonder if there’s something else at play here.
