An argument for 40–50W on the ROG Flow Z13 (Ryzen AI Max+ 395)
I’ve been messing around with power limits on my Z13 for the past couple of weeks, and honestly I think people are way too obsessed with running this thing at 60W+.
Sure, you can squeeze out a few more FPS, but after a certain point you’re just trading a ton of extra heat and fan noise for a pretty small performance gain.
I’ve settled on this setup and don’t really see myself changing it:

For me, this is exactly where the Z13 shines.
It’s cool enough that I never think about temperatures.
The fans are noticeable, but they’re nowhere near jet engine territory.
The tablet itself never gets uncomfortably hot.
And I’m still getting 60–90 FPS in modern AAA games depending on whether I use FSR or Frame Generation.
I know there are people running 60–70W profiles, but I’m genuinely curious, are you actually noticing a meaningful difference while playing?
Looking at frame counters is one thing, but in actual gameplay, I don’t think I’d notice an extra 5–10 FPS nearly as much as I’d notice the extra heat and fan noise.
Beyond 50W, it feels like you’re hitting diminishing returns pretty quickly.
Anyone else end up around the same power limits?
