I recently acquired an RX 7900 XTX Taichi, and it performed very well in competitive games. However, when I try to play heavier games like God of War: Ragnarok, the game runs smoothly for about an hour and then starts stuttering a lot. I did some research and found that it could be the power supply since the one I had was 850W, and the GPU’s average power consumption was around 400W, with a maximum of 411W. I upgraded to a 1000W power supply, and while the GPU's average consumption remained the same, the maximum increased to 574W. I’d like to know if this power consumption is normal.

PC Specs:
CPU: R9 5900X
GPU: RX 7900 XTX
RAM: 32GB Kingston Fury RGB
PSU: RM1000X
HDD: 4TB, 500GB
SSD NVMe: 500GB, 1TB
Case: NZXT H9 Flow, 9 Fans

That level of power dissipation does seem high to me, but how are you measuring it?  A watt meter on your power line would only provide insight to the whole load, not just the GPU.  Are you using Adrenalin to monitor total board power of the GPU?

I might note that since the GPU's maximum power consumption increased from 411 watts to 574 watts, that probably indicates that your old PSU was not able to support the GPU load from heavy gaming.  You made the right choice to upgrade your PSU.

I'm using HWMonitor to measure.

There's something else I forgot to mention earlier: the stuttering continues even after upgrading the PSU. I've already tried disabling XMP, uninstalled MSI Afterburner, undervolted the GPU, and rolled back the driver to version 24.5.1 (I'm currently using the latest version). After all these attempts, I replaced the PSU, and considering the increase in GPU power consumption, I believe the issue is still related to power supply. That's why I wanted to know if those 570+ watt spikes are normal.

Hopefully somebody with more knowledge of the ability of the 7900 XTX can respond directly to that question.

I am using a xcx 7900xtx. 

On my gps. I have my gps bios set to the oc mode and then oc in adrenaline as well. I average 425w stable and barely spikes to 450. 

I have a platinum 1000w psu. Are you on a single rail or duel rail psu?  If on a duel rail, put your board power on one rail, one pci port on that rail, then the other two connectors on the other rail. See if that helps

My Saphire Pulse 7900 XTX was hitting spikes up to 650w. Idk if it's normal. That was with the HX1000 1000w platinum PSU.

This was measured with GPU-Z.
