XFX 680i with GX-450 PSU No Power Up

I'm trying to power on a new setup, but am getting a brief moment of fan power, then it dies. No beeps, just a second of fan power, blue LED on mobo lights up, then off.

Going to try out swapping the Power and Reset switch connections on the mobo tonight, but I also noticed something strange when looking through the documentation. The GX 450 PSU specifies CPU Power as being a dedicated 12VDC line, however when I look at the 680i LT User Manual, the 12VDC and GND locations are swapped. I would have thought these types of connections are fairly standard ... since it's a similar board to EVGA, I looked at there documentation and it is the same. Did I fry my mobo/CPU?
There have been a few topics concerning swapping the location of a 4-pin CPU Power header, but nothing about this particular PSU.

Kinda simple, yellow wires on the clip side of the connector mean cpu power, wether 4 pin or 8 pin or 4+4 pin

Black wires on the clip side of the connector mean PCIe power, wether 6 pin , 6+2 pin or 8 pin

The CPU Power connector is as it should, but the XFX 680i manual actually has the GND and 12VDC reversed which through me for a loop. I think I have an old PSU somewhere which should be ok to boot. I'll try to boot without mem and GPU to see if things change.
Does anyone know what significance the LED colors indicate? Right now, only the blue LED lights up and I see a brief orange LED, but no green.

Changed mobo's and processor boots up at least ...

The LEDs briefly turn on with blue being on prior to power up. Sounds like the mobo is dead, but XFX has since stopped communicating once I asked for an RMA.
