I was playing Ark Survival Ascended when my system locked up. No response from the mouse or keyboard, screen frozen, sound loop about 1 second long. I let it sit for a minute, thinking maybe it’ll break out of it, and eventually had to force the power off with the power button.

I restarted my system, and now my performance in games is really bad, I’m getting about 20fps where I used to get 80-100, sometimes it gets so bad it goes into the single digits. I get stuttering sound as well and some pretty bad input lag. In Ark, I can see the textures slowly pop in over time, which normally happens in a matter of a second or two.

Looking at CoreCtrl, if I set it to high performance mode, the GPU’s power usage peaks around 150 Watts instead of 300+.

I’m running Nobara on a 7900X3D and an RX 7900XT with 32GB RAM.

Not sure how to go about diagnosing my issue here. I haven’t made any software changes, so I’m a little lost as to why this would happen.

    The cable is only rated for so much power, which could be too much for double 8 pins. Having two operated cables ensures it can handle the load.

    I personally used a single cable that carried double 8 pin. At some point, I had issues with my system crashing under GPU load. After investigating, I found that the GPU wasn’t getting the power it needed from the PSU. Looking at the cable, it had started to melt the plastic with the connector in the PSU. I replaced the cable and it was fine, but now I only use one cable per 8 pin connector.
