[SOLVED] How do I install a second 8-pin connector into PSU?

[Cubed Candy]

My old GPU only needed one 8-pin connector so I need to install a second. The only problem being I am not sure how to get to my PSU to plug the second one in.

Please...keep all this to the relevant thread.
This one for the PSU, the other for the GPU.

Sorry, can you answer my question on the other thread though?
