"...hooked up everything correctly..." "...he stuck a PCI-E 6 pin cord into the remaining 8 pin cpu atx female port..." If that's true then it's not the same problem the OP had. Obviously if he did what is stated in the second statement then the first statement is not true. Anyway if you are asking for help/advice then start your own topic instead of resurrecting/hijacking this topic.
I think you read into my post a little too much.You are correct but BEFORE he plugged up the PCI-E to the extra CPU atx, the exact same issue was occurring. I might have questioned it if there was anything even minimally different after the new PSU, but it's the exact same. The old PSU obviously malfunctioned but the system itself seemed to show no signs of change.
Anyway if you are asking for help/advice then start your own topic instead of resurrecting/hijacking this topic.
Recommend a new detailed thread of your own including all of the systems components. The MPower and the MPower Max are not the same board as the OP to begin with. They do not share the same UEFI/BIOS's, etc..
