not a complete expert but i think you should be able to put it in the other cpu pin slot and it should only fit on one side

The connectors are keyed, you can't really mess it up. The 6+2 pins and the 4+4 EPS connectors all can be connected to the same spots and are 8 pins. The peripheral and SATA are 6 pins. 24 pin motherboard connector - self explanatory. This is how they are divided:

I'm pairing a Corsair RM650 with a ROG Strix b550-f gaming WiFi which has 8+4 pin cpu power plugs. I know the extra 4 pin plug isn't strictly necessary but might just plug it in anyway in case I want to OC at some point. My PSU came with both an 8 pin and divisible 8 pin (4+4) cpu power cables.

 

Into which plug on the PSU does the second CPU cable go? On the bottom row, are both the plugs on the right for CPU cables and if so, which do I plug the 8 and 4 pin into or does it not matter?

 

(Sorry if this is a stupid question, first time builder!)

 

Thanks!

Follow the image @Analogshared.

Within those four connectors in the red shape, it doesn't matter which connector your use for your 8 pin CPU/4 pin CPU/6+2 pin PCIe cable.

Even for LN2 on a 5950x. The extra 4-pin is essentially pointless. So you could just leave it empty
