Question Gigabyte 1080ti is weird

[Loic57]

Hey guys,

My new gtx card is weird.

I connected to my computer with one cable 6+2 (*2) and it does nothing. No light, no fan turning, ...

If I switch off the cable with 8 connectors, the fan starts to run and the gigabyte is blinking... But nothing on my screen....

If I try to plug my old 1080 instead of 1080ti no issues, it Works perfectly.... Any ideas ?


I have a Corsair cx600 watts.

You need to list your full system specs. How old is your PSU?
The CX series are the budget ones from Corsair and they are notorious for causing problems in various rigs. They should not be used in a gaming rigs.

I wanted to change m'y PSU... So maybe it will fix my issue, even if I have it since 4 years and it worked with my 770gtx, 1070gtx, and now my 1080.

I will change my PSU and come back after that !

You should also check other things while you wait for the new PSU.
Use DDU in safe mode to uninstall and reinstall your drivers.
Make sure you have the latest BIOS. If not, upgrade it.
Check the GPU in another PC to see if it works.

Was the GPU new or used? I know you wrote new, but you might bought it used so it's new to you.

You only plugged in one connector! 1080Ti has 2: an 8-pin and 6-pin. The fancier models have 2x 8-pins.

No, I plugged both connectors.

If I plug both, it does nothing to the card, no light, no fan turning and nothing on screen

If I plug only one connector (the one with 6 pins) I have the light and fan turning, but nothing on screen.

I'm about to buy this PSU : Aerocool P7850, to get the full P7 set

Don't buy Aerocool PSUs, poor quality.

Do not buy Aerocool. Almost all Seasonic models, Corsair except the CX and VS series, Leadex, Leadex II and Golden Green series from Super Flower.

3rd'ed?
Power supplies aren't just made for gaming oriented builds. There's also office PCs, and that Aerocool fits the latter.

Hi there,

I received my new PSU and it changes nothing, I think the issue comes from the GTX18080ti, I did a video to see what is happening exactly.

At the beginning of the video we can the light "gigabyte" is off with no fan turning, and when I unplug the 8pin connector, the fan starts to run and the light "gigabyte" is blinking.

Maybe my Z270X-Ultra gaming is not compatible with the graphic card ?

...
It's because you're plugging both 8 and 6-pin sockets on a SINGLE CABLE. You HAVE to use 2 DIFFERENT CABLES.

But why ? Why do I have a cable with 2 connectors If I need 2 ? Why this 2 in 1 cable stands for ?

 

[Phaaze88]

That 2-in-1 cable worked for older cards, and other less power hungry devices.
That will not work for this [still] beast of a card.

Ok I have now connected two câbles from the PSU to the card and I see the same result...


Édit : I think the card has an issue, I checked on others forum and everybody say I can connect my card with one or two cables, it changes nothing.
I tried all cables which are in my PSU box, without any effects
