3080 ROG Strix broken ? Short cut ?

[Tracteurer]

Hello, a few days ago, I was playing when you suddenly, my pc turns off. It didn't make me I had done that before. So I try to turn it back on but I just hear a little noise from the power supply, like a click. When I unplug the graphics card, the pc runs and everything works, when I put another graphics card, everything works. After several tests, I realized that when I remove one of the 3x 8pin cables, the graphics card and the pc work. Is it a short circuit? If so, can I fix it? It did the same thing in a friend pc. Thank you in advance for your help and advice. The graphics card is an ASUS rog strix 3080 ROG-STRIX-RTX3080-10G-GAMING

Hi @Tracteurer 

The PSU detecting improper current balance due to a poor cable may be the cause. Do you have the OEM cables for the PSU?

[Tracteurer]

I tried with the 8 pins cables coming with the power supply and it didn’t work.

Do you think the performance bios broke ?

Doubt it's anything to do with the VBIOS. Try switching to Quiet BIOS, though. If the PSU is "clicking" and the system does not power on with all three cables, it still indicates some form of power issue.

Do you think the graphic card is broken or it a power supply problem ?

Hard to say vicariously. If there's no discolouration on the 8-pin connector and the GPU powers up fine with two cables, it's more likely to be the PSU rail.

What PSU is it?

RM850X

If the GPU is exhibiting the same behaviour in two systems, open a support ticket with service for your region
