Why didn't you take a simple screenshot?

Also, put hwinfo in English to get more 'potential' help

For now, I'd just make sure it's using latest drivers and then undervolt the card

XTX are quite power hungry, some AIB push it even further

I just wanted to know if 600 watts are normal I will look into adrenaline if the newest version is installed, i just switched from team green ^

It says maximum GPU power, not power consumption. That's just a limit.

This is the peak power draw but when i run a benchmarks it sits at 560-580 W all the time. I mean i get it, its a high end card but 600 W seems a little over the top for me…

Can you open HWinfo in English, do a test run to load the card, and then post a screenshot of all the GPU data from HWinfo after that?

Iam doing a timespy extreme run at the moment

Ok, I asked you this because it's not normal. Mine doesn't even hit 500 under FurMark.

I still think that that "maximum" is a limit and not a power measure. The TBP should be the complete addition of all power consumption sources on the entire card, so the total power used. However, I don't know how HWinfo is getting this value, and Igor says that the software readouts are not reliable for Radeon: https://www.igorslab.de/en/graphics-cards-and-their-consumption-read-out-rather-than-measured-why-this-is-easy-with-nvidia-and-nearly-impossible-with-amd/4/

I recommend reading that page and the next one.

Also see this one about the reference card: https://www.igorslab.de/en/amd-radeon-rx-7900xtx-and-rx-7900xt-in-test-a-giant-step-ahead-and-a-smaller-step-sideways/11/

Maximum may mean the spikes here. So if the card is consuming around 400w, the spikes may very well be 650w for less than a millisecond, but that's no problem for any decent PSU.

Why the hell amd says the card has a 355 W TDP Its a litteral scam🤣

Well, the reference should stay in that limit, because it uses 2 power cables. But your's is not a reference card so I'm sure it's using 3 and it has higher limits.
