Cable connectors burning on both end - is the 3090 or the cable the reason?

[Micha]

Hello,

a few days ago it smelled like burnt plastic when rendering, so I shut down and restarted the computer. The computer was running fine again, everything seems to be ok? But in the last days my screen goes black from time to time and today I found the cause - a cable of the 3090 shows burn marks. The connector on the power supply was melted and dark on the graphics card. So this one cable got too much power.

What should I do now? Should I send the 3090 to a technical check or is it "normal" that the high current can burn weak cable connectors? The PSU is a good one from Enermax and working since years.

I am curious about your experiences. (Muhammed_Hamed , have you ever experienced something like this?)

Hey Micha,

This is not a surprise in the type of machines, I had this happen multiple times as well. Don't worry much, replace any damaged cables. It is best if you check all of them
After that you can stress test your GPUs for some hours to make sure everything is fine again, on both stability and temperatures

Best,
Muhammed
