I'm looking for help with a build that will not run.

In short, with the PC powered on, the CPU cooling fan runs and the hard drive runs but there is no light from the optical mouse and the keyboard LED's won't come on. There's also no video.


The components:

Gigabyte GA-78LMTUSB3 mother board

XFX TS550 power supply

Crucial Ballistix Sport 8GB Kit (4GBx2) DDR3 1600 (PC3-12800) 240-Pin UDIMM Memory

AMD FD6300WMHKBOX FX-6300 CPU

I suspect I made an error in installing the power supply, possibly with the ATX 8-pin connector. Power supply documentation is sparse.

Any suggestions of what I did wrong?
