pc not booting with right pci-e power connected to gpu

After i turned of my computer because it froze up, i tried to turn it back on again. It didn't. After troubleshooting everything(checking if psu was working, pc started without gpu connected, etc) i finnaly think i found what the problem is. The right pci-e 8 pin slot on the gpu. When i plug in 1 of my pci-e cables, the pc boots. after turning it off and removing the cable from the slot and putting it in the right slot, it doesn't boot and my power supply gives a little pop(i think it is a short, don't know how though). With the gpu pluged in, it doesn't turn on, because it NEEDS both power cables to run. I have a gigabyte aorus 1080ti. Please help me with this issue, if i can't fix i will have to buy a gpu pretty fast, since i will be getting a ryzen 9 5950x tomorrow. Thanks in advance

does the system work with a different dual 8 pin GPU? Also I'm a bit confused:

if it's booting without the second 8 pin, why does it need both cables?

 

if the 1080 doesn't work in a different PC, you might have a short in the card.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus threadUserbenchmark (Et al.) is trash explained, PSU misconceptions, protections explainedgroup reg is bad

The card has some debug led's, which turn on when one of the pci-e connectors isn't connected. When i connect one of the power cables, the integrated graphics also don't show me anything, which is a bit weird. I am currently updating the bios of the motherboard, let's hope this fixes it, I don't have high hopes though

My pc does start with 1 cable plugged in, but i don't get any output to my display via the igpu or 1080ti

That's because it needs both to work as a video card.
It has enough power to tell the motherboard that it is a video card, so the iGPU is disabled, but not enough to output video.

So i tested it again, The igpu is still seen as the main gpu, and when i look in the bios, both pci-e slots i tried show nothing in the slot when the gpu is in it. I guess I'm gonna have to buy a new gpu. I will try the 1080ti in my new pc tomorrow, but i don't have high hopes for it

If that doesn't work, try the oven method.

If you don't have one, check attics.

i can try that tomorrow, don't really feel comfortable putting it in the oven, but if it is already broken for sure, there isn't really much to lose
