I have just finished my first custom loop and my pc and my GPU is not being detected. It has two little white LEDs but that's when the 2x 8 pin wires are disconnected, they turn off when I plug them in.

The strange thing is that the RGB doesn't turn on only when I unplug and the plug the connector back.

I have searched the BIOS, updated windows, disabled the on board graphics.

Could it be a psu issues but my motherboard is not showing that the GPU is not connected.

My setup is :
8700
MSI Z390 gaming pro carbon
Aorus waterforce 1080 ti
16gb corsair ram
corsair 1000 rm

Any info would be grateful.

Are you using two separate 'independent' 8 pin connectors/wires into the GFX card - i.e. not both split off the same PCIe cable?

It shouldn't matter with a quality PSU but as you have the option i would definitely try this.

Alternatively, if you are using two independent PCIe cables try alternating between spare PCIe cables (i.e. using connectors on same cable) and alternating outlets - just in case you have a faulty outlet or cable/connector.

Thanks for the reply, I'm using 2 separate 8pin wires and I have tested them but change the wires as I have 4 sets. Switching between different slots on the psu and the GPU, if that makes sense.

There is not much information on the Aorus website about the little white leds? I will try and upload some photos.

EDIT:
Also could try the following to rule them out (if you haven't already tried):
  • try alternate PCIe slot
  • clear CMOS/or even update BIOS
  • Make sure you're plugged directly into the wall and not an extension cable
  • skeleton setup - 1 stick, no hdds etc
  • Check that the motherboard is firmly fixed to risers - no movement.
  • Check around PCIe slot for anything unusual - even within it.
  • I would suggest running a simple setup outside of the case and jump starting the system - but suspect your custom loop makes this problematic.
  • Re-seat card a couple of times - may be a contact problem that automagically corrects itself with a few reseats.
 
From above list - have you tried alternate slot?

I would also try re-seating a couple of times. It's an easy test and can sometimes magically fix all.

  • try alternate PCIe slot CAN"T AS THERE IS ONLY ENOUGH SPACE FOR THE FIRST SLOT.
  • clear CMOS/or even update BIOS. DONE.
  • Make sure you're plugged directly into the wall and not an extension cable NOT TRIED THIS, DOES IT REALLY MATTER?
  • skeleton setup - 1 stick, no hdds etc SAME AS ABOVE
  • Check that the motherboard is firmly fixed to risers - no movement. NO MOVEMENT
  • Check around PCIe slot for anything unusual - even within it. CHECKED AND GOT MY ROCKET BLOWER OUT.
  • I would suggest running a simple setup outside of the case and jump starting the system - but suspect your custom loop makes this problematic. I WISH.
  • Re-seat card a couple of times - may be a contact problem that automagically corrects itself with a few reseats. DONE LOADS.

Sorry about the caps just wanted to reply to your suggestion.

Do the plug in the wall really effect the psu? Also the skeleton setup what's the advantage? Never heard that one before.

Thanks again.

  • Plugging directly into the wall is a very valid test - if that's not possible try a different extension cable. You can have the best PSU but it's still very dependent on the quality of the supply - extension cables can cause lots of strange anomalies if faulty'
  • Skeleton setup reduces amount of other components that MAY be causing the problem. Reducing the amount of components attached to the system is part of the process of hopefully ruling them out. I had a SATA lead that stopped a system form getting past post :/
  • 1 stick of memory and alternating slots (and sticks) - same as above plus faulty memory can sometimes display it's problems in weird and increasingly annoying ways. Again, a quick simple test and hopefully rules it out/or in.

Well the plug in the wall didn't work :(

At least it's something ruled out - it can be a slow, laborious process troubleshooting :/

You could try disconnecting the front panel header and shorting the power pins to start the system once you have your minimal setup.
 
To be honest I think the gpu is dead, it's the only thing that is second hand, I need to find more info on the white leds where you connect the 2x 8pin wires to the GPU. Also the seller on eBay was very fast to say they will give me a refund without really asking any questions, apart from saying sorry.

It's probably still under warranty and Gigabyte has UK RMA - maybe worth considering if seller helps with return.

I have a vertical raiser cable. Would that work?

If you mean a PCIe vertical riser kit/bracket then potentially - would the smaller connector from the extension allow you to test the other PCIe slot?
 
Led should be off when plugged in and system turned on.
When they are flashing, poor supply or power, if left on then no power getting to the cards.

RGB is controlled via software and can turn off if not installed
