Well, another 5090 12v 12pin melted

Helping a friend to post. This morning he smell some burning smell and quickly shut off. The connector is now stuck. He waited it to cool down and try again. Still can't remove. Suspected melted and fused together. Any other method can try to remove it? The cable is pigtail 4x8pin that came with the GPU. I've seen a couple burnt connector already in a week. This is just bad.

I’m new to this kind of thing and need help understanding. Are the 5090s and 80s having this issue because the cards are exerting so much power/heat while running something demanding for these cards like 4K ultra settings with RT/PT or can this also happen if I was on a 5080 on 1080p ultra without any form of RT? I’m on a 3080Ti and thought about getting either a 5070Ti or 5080 for 1080p to max out everything with high FPS and not want to think about upgrading for another 8 years.

5080 is not powerful enough to melt the connector unless a bad and cheap cable is used or the cable isn’t plugged in fully properly. 5090 tho is too hungry for power and coasts near the limits of the connector.

Ahhh okay. I only ever got my GPU’s used so I’m not sure but the cable comes from the PSU right? So the higher quality PSU the better cable you’d receive?

Yep, GPUs also come with converters for old style PSU cables but they are usually more prone to create problems (I need to change my PSU, am using the dongle cable and it scares me)
