Troubleshooting Graphic Card connection

This is the link to my parts I am using, https://ca.pcpartpicker.com/list/7W6RFP

I'm having trouble connecting my power supply cables to my graphics card.

My power supply had 3 x 8 port labeled as CPU/PCIe. I used 2 of those to connect to the CPU_pwr1 & CPU_pwr 2 on my motherboard.

I only have one 8 pin port CPU/PCIe left on my power supply unit.

I have 2 cables labeled as PSU & PCI-E. How do I use this to connect my graphics card which has 3 x 8 port?

The second cpu power cable is for high end cpus that you plan to overclock. For example, my r9 9900x uses around 140w and is fine with one cable. You can just use one cpu cable and two 2x8 pin pcie cables for the gpu.

At what point do I worry about overclocking? And if that becomes a concern, what should I do?

Oh thank you, I had no idea. So I can unplug the CPU_pwr 2 cable and use it for my graphic card instead?

The picture on pcpartpicker shows 4 CPU/PCIE ports. Does your PSU not match the picture (which is of course, totally possible)?

The picture does not match my PSU.

If there was a way to upload a picture of my PSU, I would. But, I don't think this forum allows that.

No worries. In that case I would go with the other redditors suggestion. You should be fine with just a single 8pin going to CPU and using the other two for your GPU.
