Question Graphics card with PCIe Extension Cable issue

[benkingery]

Hello:

I have a son that is DYING to play some pretty beefy games. I have a decent core unit (i7 processor, with 16 GB Memory, 256 SSD, 64 bit OS). But the graphics card was a little lacking, so the game is super choppy. I'm new to all this, so to test, I bought him a GTX 560 GPU. When it arrived, I realized it wasn't going to fit inside the PC case, so we started looking at PCI extension cables.

So, we just got our 20 CM extension cable, plugged the GPU in, computer fires up normally, but there is no video output. So I figured maybe I need to install drivers for the GPU, so I power down the computer, re-install the old Graphics card onto the PCI extension cable, and fire the computer back up and STILL NO VIDEO OUTPUT...

So, I remove the pci extension cable, reinstall the original graphics card inside the original PCI slot, and it fires up normally and fine.

At this point I surmise it has to do with the PCI extension cable, but I have no idea why it wouldn't work.

Can anyone on here give me some ideas for how to troubleshoot this???

Thanks in advance.

It's a PCIE3 16x 20 cm cable. Bought it on Amazon.

The pins on the motherboard side of the cable match up perfectly to my existing graphics card. And on the female side (where the GPU plugs into), the GTX 560 fits perfectly into the slot.

Not very hard to guess at the issue, you tried two cards with that extender, neither worked. Card without extender work.
Educated guess, the extender is bad, exchange it.

What are the full specs of the computer, including motherboard brand model and power supply brand and model? This some store bought PC like a Dell/HP?
