Gpu stop lighting up after connecting 2cd pci while pc on

[NtiX]

I recently got a new gpu. When I’ve connected. Only with one pci 8x every thing would start only the message would show up “Please power down the pc and connect the second pci cable” and I so I found 2x4 pci what was coming from the inside of the power supply and I connected it but the pc wanted start so I pulled out the 2x4 and pc turned on. When I tried the second time I thought the pc was off and when I putted it In there was a electrical cracking sound and after that the pc would turn on the the gpu want even light up. Can someone tell me what happens to my gpu?

What GPU?

What power supply?

What mobo?

Basically, it sounds like you killed the GPU by plugging in a power connector while it was on, causing arcing and damage.

You shouldn't have been able to plug an 8-pin EPS motherboard power cable into the GPU.
You can do it if you push hard, though.

They look similar, but are not the same pin-out or socket arrangement.

I would think that would have killed more than just the GPU, though.
