Can you give us more details ?
How did you diagnose your PSU ? . What is the exact problem of the old board (no display or not powering on ? )
Is the replacement motherboard powering on or completely dead ?

It could be an add on card. To properly test a motherboard, just put only CPU and RAM in it. Then connect the SMPS and check if it works.

True. Just because it will start on its own does not prove it will deliver the required voltage under load. Try the other PSU.

I can't find anything online to show me the motherboard. How does the power button attach ? just two wires ? can we bypass the button to eliminate that.
remove everything except CPU (soldered in on this machine) , Ram, will it start ? Fans come on ?

got the picture but it is not labled. Where does the power button connect. if it is a two wire connection you can remove the wires from the pins on the motherboard and jump the two motherboard pins with a small screwdriver. just touch and then remove. If the board fires up then the problem is the button. If it does not then it is either the board, the cpu or the ram.
On this model the Cpu is soldered into the board, did your new board come with a new CPU also ?
You have known working ram in the other unit. You could put one stick of that in non working unit to test also.
And it is possible that your new board is no good.
