I'm building my first HTPC and came to problem. I have an ASUS H97M Plus motherboard and a Seasonic G-360 power supply. The motherboard has an 8-pin PCI-E female slot. The power supply has a 6-pin PCI-E male plug. Can I plug the 6 into the 8 receiver with plowing something up? The 8-pin has an offset clip anchor as if design to receive a 6-pin. Or should I purchase a 6-pin to 8-pin adapter? Thanks in advance for the help.
