My motherboard is a Gigabyte GA-H97-Gaming 3, PSU is an XFX TS 550W, and my Case is a Rosewill Challenger. I have my build extremely neat but i can not find a way to hide my CPU 8 pin because it is to short and my Case does not have a hole in the back around where the i/o shield is. I was things of maybe going under the motherboard with it and come out at the top lest where the I/O shield is and connect it, will that hurt my motherboard? But i was wondering will my 2X4 pin connector work the same as my 8 pin? Because my 2X4 pin is much longer so i may be able to do more with. Here is the link to the three parts if needed below, thanks guys!
