No image popping up on monitor on boot

[Birdfeather]

Hey guys, I just bought a computer (with your help!), and I just finished building it. However, when I turn it on, no image pops up on the monitor. I was curious if you guys thought it might be because of a wiring mistake I may have made.

The GPU came with its own set of PCI-E wires, but I used the ones that came with the motherboard because they plugged directly into the PSU from the GPU. I'm curious if you guys think that was the mistake? The fans on the GPU are still working despite this but maybe it's just...wrong? Here's a picture of the PCI-E cables the GPU came with

I didn't want to use them because if I did I wouldn't have had enough of the plugs for the case's fans.

I noticed the prongs for the PCI-E cable that came with the GPU didn't look the same as the ones that came with the motherboard.

Here's some more pictures of the overall cable work.

I really appreciate any help I can get once again, thanks a lot.

+1 Connect the monitor to your video card, should be set to go.
I'd be surprised if something else is wrong.

P.S. Cable Management!

Should be fine. when you put in a video card the onboard one is disable
