PC won't turn on.

[IronSolaire]

My pc won't turn on, and I haven't a clue as to why...

I recently learnt that I had pigtailed my GPU using the y-pcie cable and that it would be safer to use two discrete pcie cables. I made the swap and now it won't turn on.

 

I made sure to turn off the pc and the psu. I unplugged the psu too before working on it.

 

SPECIFICATIONS:

Aorus X570 Elite

AMD Ryzen 7 5800x

Gigabyte 3070ti

Corsair RM850x 80plus Gold PSU

Kingston Fury 2x8 GB RAM

Corsair 4000D Airflow

Undo the changes and try again. Make sure all connectors are properly inserted. Does the PSU have a separate power switch? Make sure that's ON.

Make sure that your cables from the PSU to the GPU say “VGA” . Depending on how your cables are keyed, you might have accidentally connected a CPU cable instead of a GPU cable.

 

The GPU “VGA” cables will have a 6+2 split end, and CPU cables have a 4+4 split end.

Tried this. Didn't work. Made sure the PSU switch was on.

None of the cables in the box say VGA. Some are 6+2 PCIE connectors and others are CPU 8 pin connectors...

the cpu 8 pin connector you can probably split to two 4 pin connectors.. 

the 6+2 are the correct ones, check that all connectors on the PSU side are connected properly.. then GPU CPU 8 and 24 pin.. or what key they use.. 

check that your power button are connected correctly, it should be keyed, pw_sw and usually the top left two pins on that multi cluster. at bottom right of your board.  worst case, you can just short those two pins with a screwdriver quick to see if it starts up.

You will only want to use the cables that say PCIe. Are you getting any lights on the motherboard or signs that the system is getting power at all? 

Did you use the included cables that came with the PSU? If you used another vendors cables it would not be compatible. Make sure they are Corsair cables.
